and it was always engaged in the ZJs. The Quadra-Trac II/Quadra-Drive is rear wheel drive only until there's a speed difference between the front and rear, which then causes the PC in the t-case to connect the front and rear together.
Yes, same system with the quadra-drive I think as they share the same transfer case, just adds front and rear limited slip differentials in the quadra-drive.
I have a 2000 Jeep GC WJ with Quadra Drive. I drive in snow/ice 90 percent of the time during winter months and have never found a condition that the WJ didn't perform flawlessly. I use Thunderer 265 which measure 32 inches, no studs, perform well in all conditions!
it works way faster than the video describes, it basically all happens at the same time... the front and rear limited slips and the transfer case. works damn good in michigan winters, you just have to get used to it, if the wheels are spinning and you arent going anywhere, give it a tad more gas and youre off. not quite the same way it works in a 2wd car lol
Narrow, steep, icy climb this weekend. Trail was too narrow to turn around and too steep. I went for it in 4-lo in 1st. It didn't even break traction. this is with no lift and Wranger TrailRunner ATs. I was amazed.
Picked up an 04 WJ with the Quadra Drive and the H.O. 4.7 that had turned into Dual Drive only, the T case was bad. Pulled it and put a 242HD Select Trac case in it, paired with the Vari Lok axles trails pretty good. The axles are kind of noisy when the Lok is engaging and it takes a bit of tire spin to get them to engage, but for factory parts and a 3.5" lift with 265/70-17 General Grabber X3 tires it surprises quite a few people.
This is awesome to hear about my sister has this exact jeep and I was looking this info up for her and it helps to know this ty for the you tube video😆
This sounds great in practice. But, i find it to lack when using. It doesn't allow to to retain momentum or gain momentum like you would do normally in say 4 hi. You engage 4hi before you lose traction on your back wheels so you don't slow down and get stuck. We have this system and the good old slectrac on a zj and the zj is way better in the snow. If things get real bad we put it in 4 low. Though 4 low works normally on quadra drive also.
My WJ Grand Cherokee was optioned from new with Quadra Drive II and love the traction. If your not sure what you have check the diff tags or get the VIN and ask for a build sheet from Chrysler.
i did seem to see that the 2nd generation version the quadra drive II works way much better like in the commander than in this grand cherokee model which used the first gen
Yeah in theory. I figure it would be worse. But in sometime it helps since it keeps your wheel speed down which i think is more of a factor with slipping is involved.
4 low in the snow? I would think that would cause more problems than help multiplying your torque would end up with less grip and more wheel spinning. In my XJ all I ever needed was 4-hi to get through anything on the roads. But yes, these AWD systems that apply the brakes to maintain grip do inhibit forward motion in the winter. I'm always turning off the ESP on my Audi to get a little bit of wheel speed to dig through the snow.
no most all wheel drive systems have an open center differential in place of a transfer case with no low range gear reduction. quadradrive and quadratrac has a transfer case that will lock when the rear wheels slip, acting like a part time 4wd transfer case. quadradrive has front and rear limited slip differentials, quadratrac does not. they both have a a low range which locks the center differential regardless of wheel slippage or not.
The viscous coupler in the transfer case works great, and easy to know when they start failing because your full time 4WD system starts feeling like its a part time 4WD system because the front end will start to bind when turning. Quadra drive and quadra trac both use the same transfer case, quadra-drive just adds the limited slip viscous couplers in the front and rear differentials...great system but many say the viscous couplers start wearing out around the 150k range. my 96 Grand Cherokee had 219k on it when the viscous coupler in the quadra-trac t-case started failing, that thing was pretty good offroad with open differentials so I'd hate to see what it would have done if I had the quadra-drive system.
Just got a original 99 Grand Cherokee Laredo with 4.0 and it says Quadra Trac 1 below the transmission stick and mine doesn’t have a low range or a 4wd stick or selector. It just says Quadra Trac 1 on it. Mine is a Utility Grand Cherokee Laredo. Haven’t had it off-road yet but it’s rust free and in great shape
Quadra Drive is okay, but Selec-Trac is basically the best 4WD system out there. You can go into 4WD full time - which is basically AWD - or lock your axles and go into 4WD part time. Both are great systems, but Selec-Trac is the top shelf 4WD system for both needs.
Quadra-Drive does not have 4 Low, Quadra-Drive 2 does though. Not sure why Jeep thinks they need so many 4WD systems LOL...I have counted 17 different systems, yikes, that's way too many. 2-3 would have been plenty.
@@wildbill23c your both wrong select trac, as well as the nv247 based quadra 1 tcase both have 2.72:1 4low. Quadra-trac 1 doesn't have 4 low. Quadra drive is based on quadratrac 2 with nv247 using gerotor pumps. Quadra drive 2 using quadratrac 2 when it was switched to nv245 that has a center dif instead of a pump. So quadradrive is gerator pump based rwd, pump progressively locks variloc axles and the t case to go 4wd. Quadradrive 2 using a center a dif and acts as awd and locks the center as needed for 4wd and locks the axles electronically
@@SarabLoh hi their! U seem to know your 4x4 stuff! Can u help me? I have a 2001 jeep grand cherokee 4.7 auto. I'm in the process of changing the diff oil!

It won't hurt to add it, but I'd like to know what's correct!
@@wildbill23c Um.. Qudradrive Does have 4low. I own one. Ignorance in comment section on videos it's truly mind-boggling. Also some people seem to think qudratrac and qudradrive are one in the same.
No i have it on the lift but front diff feels nice and loose i can spin it fine but the transfer case is the one that feels like it jams up and also u joints on shaft are good 2 ..
No, just limited slip, the newer ones had only rear limited slip while the older models had front and rear limited slip. You can get aftermarket lockers of course though.
Rear differential Hi guys! Im new here...hope you can help. I have a 2004 jeep grand cherokee overland with factory tow pkg. Recently i got my rear differential replaced. Today went off roading for the first time after the rear diff swap and felt the 4wd system a little weird, meaning i was not feeling the quadradrive engaging as it should. Came home wondering if the new rear diff they installed was from another quadradrive or not. Is it possible for my wj quadradrive to eaven run if the new diff they installed was not from a quadradrive? Also how can i find out if its a quadradrive rear diff i got? Maybe a label or something stamped in the diff?
No then like any other four-wheel you can lock your 4-wheel low.or put the bitch in neutral and have your friend till you out LOL what are yourself out with a winch
I have an older Grand Cherokee that is in great condition for its age. I'm wondering if the Quadra Drive system could be retrofitted. A friend in another State inherited a Grand Cherokee involved in a major rollover and, except for the drivetrain and a few other bits, it was destroyed. Would it be a major job to transfer the parts over?
Its certainly possible. The quadra-drive system uses the quadra-trac 4WD transfer case, the only difference between the 2 systems is that quadra-drive also added limited slip front and rear differentials using a viscous coupler in the differentials to transfer power side to side, so all you would need would be the limited slip axles.
I have a 2011 grand Cherokee overland hemi. Qd2 and qlift. When I am in 4low are all 4 tires locked? Or do I just have limited slip rear end? The dealers don't seem to know anything about the systems.
Yes, low range 4WD locks both the front and rear axles to a 50/50 torque split...the viscous couplers in the front and rear differentials then send power between each wheel on that axle depending on traction, but in low range both the front and rear axles receive the same amount of torque.
Yo m8, recheck your facts, I own a 1998 Grand Cherokee LTD 5.9 and I DO have the Quadra-Trac,or Quadra-Drive, it's even witten on the plastic console part for the 4x4 handle. (Quadra-Trac). .
Yes but my front diff is making a winding noice i replaced it and it still makes that noice and i feel it braking on its own could it be a bearing in transfer case?
Rene Torres I have no 4WD at the time my axle shaft broke so I have to replace that. But In your case It's defiantly NOT the t-case It's something In the front differential.
I put one in from the junk yard opened it and serviced it look good but when i take the drive shaft off and spin the transfer case with hand it feels konda tight and then ot loosens up again i might take it apart soon
Quadra can go from highway to mud and lock all 4 wheels without selecting a 4wd mode or pushing a button to lock something, show me a vehicle that can do that in early 2000s, i know alot run open diff in the front so get a wheel off the ground and your screwed, quadra has the equivalent to 2 LSDs.....beat that kids
it wont...ran mine without a front driveshaft for months...will spin brodies like a mo fo....its hard on the tcase though because it tries to send power to a drive shaft that isnt there.
That's why you see so many 4x4's and AWD's off the road every snow storm, all that stuff makes people way too overconfident. The vehicle has the capability to fly down the ice covered road at highway speeds but the driver's driving capability does not.
hey guys i got a 2001 grand cherokee with wuadra trac 2 and was wondering if i remove my front drive shaft will it still work to use only the rear whells or will it try to send all the power to the front?
Says who? I have a 04 and 02 GC Limited H.O. and I have seen no bias between the front or rear except when conditions dictate..I have 3 videos I put up for a friend in Portland when he was considering a Highlander showing my 04 in snow..he bought a GC
@@ferrelx the Quadra drive is going to work very well in slippery conditions like mud, sand or snow, but if you’ve ever taken your jeep rock crawling and tried to put some real torque through the varilock you would see what I mean. There’s no comparison to actual lockers. And the front varilock being a much smaller Dana 30 is going to have smaller weaker clutch plates.
@@tliggexperience I completely understand your point..let me add this..when you start having the issues you are speaking of is when you add hp/tq and or ad a taller/heavier tire to the factory setup..I would even go as far as saying this applies to all rigs out there.. I will say this..when I changed out the rear dif on my 3/4 76 Power Wagon for a lock right locker I was surprised to see a clutch pack in the Dana 60..fast forward to couple years ago when I swapped over to Amsoil in my 04 I pulled the carrier out to see what this setup was all about..I was surprised to see the clutch assembly was nearly as large as the ones in the Dana 60.. So I don't think they would be the weak link here..most likely the axles like most other setups will let go before the clutch assembly goes..the 4.7 H.O. puts out 330 fpt @3600 rpm and in low range its a BEAST but some guys need more..sooooooo..you know the rest 👍
@@ferrelx I don’t doubt the clutch pack is big, it works really well for an lsd. I’ve never looked at mine but I’ll take your word for it. In spite of it, my jeep is bone stock with 28.5” tires and I’ve been twisted up in ruts uphill and had the rear varilock just slip and not cut it. But from a design standpoint if it didn’t do that then every time you tried to make a u-turn on pavement you’d skid the tires. It’s a good diff for most scenarios but there’s a reason rubicon’s come with proper selectable lockers.
@@tliggexperience I can only give you my experiences with my 02 and 04 Limited H.O.s..1st I run Amsoil as all my lubricant solutions in my rigs..Synthetic Tractor Hydraulic/Transmission Oil SAE 5W-30 in the transfer case and SEVERE GEAR 75W-90 in the Vari-Loc axles with AMSOIL Slip Lock Differential Additive in all 3..you refer to the setup as lsd's when the are not..lsd = limited slip differential that can't lock up due to design limitations..that's why most are wore out by a 100,000 miles..Vari-Loc is a progressive system that tightens all the way to full lock if necessary..edit: buggy ass youtube left half my comment off..i'm tired and going to bed..
BNelson M if all tires loose traction... What do you expect it to do... add a fifth tire? If you were to say you floored it and 1 tire did a burn out or both rear did, your statement would be valid. But all your comment did was prove it works
This is Garbage. On my 98 5.9 limited all 4 wheels seemed to always lock together. You cant beat tank-like traction. I wouldnt want any of the wheels just sitting there while the other spins and does all the work.
I wouldn't want this on my car, i want to turn it off and on when i need it, i wouldn't want to be driving up a steep hill for my car to decide, oh well you have traction, you dont need four wheel drive, then turn off 4 wheel drive on me.
That's a real spiffy system for a permanent awd setup in a car but utterly useless garbage on a real jeep. When I put my older jeep into 4wd, all four spin at the same rate which makes for much more predictable drive qualities. When I need the traction to get out of 2' of snow, I need all four wheels getting power right away, not whenever the computer thinks I need certain tires to spin.
lol thats not how quadra drive works thats the basic understanding of how all ALL WHEEL drive cars/suvs function the only difference between your over rated jeep and a mercury mountaineer is the mercury uses abs sensors to apply the brakes to control the wheel spin reduction system, which in my ASE master certification opinion is a much more reliable and cheaper system to repair incase of damage :)
Quadra-drive uses the same transfer case as the quadra-trac system uses, the only difference is quadra-drive adds the limited slip front and rear differentials...and the quadra-trac system splits the power 48% front and 52% rear, so really its not in a 2WD mode ever, it just varies the torque depending on traction conditions and can send 100% of the torque to the front differential or rear differential if needed...the viscous coupler found in the transfer case many say lasts about 150k, I had 219k on my 96 Grand Cherokee when it started to fail which just turns your full time 4WD system into a part-time system LOL. I assume you are talking about the newer Mountaineers? The older ones shared the same basic viscous coupler system like the Jeep quadra-trac. The newer mountaineers definitely use abs to help with traction. Both systems work great until they wear out ;).
Got an 03 WJ. Handles pretty much anything, really well.
Grand Cherokee keeps moving when all those fancy SUVs are stuck
I have 04 WJ and Quadra Drive is awesome thing on Jeep!!
and it was always engaged in the ZJs. The Quadra-Trac II/Quadra-Drive is rear wheel drive only until there's a speed difference between the front and rear, which then causes the PC in the t-case to connect the front and rear together.
1998 ZJ 5.9 had a first similar system... Quadra-trac with nv-249, but it only worked between front and rear axle, through viscotic clutch.

Quadra Drive and Quadra Trac are Different Setups
The transfer case is the same between the 2, the only difference is quadra-drive adds front and rear limited slip differentials.

It will try and send power to the front, and in some cases you may not move at all with the drive shaft removed.
So it turns out in reality the front varilock does almost nothing while the rear works reasonably well but not perfect

So I don't think they would be the weak link here..most likely the axles like most other setups will let go before the clutch assembly goes..the 4.7 H.O. puts out 330 fpt @3600 rpm and in low range its a BEAST but some guys need more..sooooooo..you know the rest 👍
@@ferrelx I don’t doubt the clutch pack is big, it works really well for an lsd. I’ve never looked at mine but I’ll take your word for it. In spite of it, my jeep is bone stock with 28.5” tires and I’ve been twisted up in ruts uphill and had the rear varilock just slip and not cut it. But from a design standpoint if it didn’t do that then every time you tried to make a u-turn on pavement you’d skid the tires. It’s a good diff for most scenarios but there’s a reason rubicon’s come with proper selectable lockers.
@@tliggexperience I can only give you my experiences with my 02 and 04 Limited H.O.s..1st I run Amsoil as all my lubricant solutions in my rigs..Synthetic Tractor Hydraulic/Transmission Oil
SAE 5W-30 in the transfer case and SEVERE GEAR 75W-90 in the Vari-Loc axles with AMSOIL Slip Lock Differential Additive in all 3..you refer to the setup as lsd's when the are not..lsd = limited slip differential that can't lock up due to design limitations..that's why most are wore out by a 100,000 miles..Vari-Loc is a progressive system that tightens all the way to full lock if necessary..edit: buggy ass youtube left half my comment off..i'm tired and going to bed..
I'm gonna call bs because I can spin all 4 from a launch in my 2002 grand Cherokee overland 4.7 v8 H.O.
BNelson M if all tires loose traction... What do you expect it to do... add a fifth tire?
If you were to say you floored it and 1 tire did a burn out or both rear did, your statement would be valid. But all your comment did was prove it works
this proves it works bud, but i seriously doubt the 4.7 can spin all 4 tires on anything but a wet surface
does anyone know if quadra drive is on 99 jeep cherokees?
paaaaaahzitraction
fonzitraction?
Sounds like if one thing goes wrong your bank accounts gunna hurt fixing this bs system
Not a bs system if it still works 16 years later
No thanks, Ill take a part time transfercase with air or electric lockers. To much shit going on in here IMO
same thing, fancy words
I don't understand why this is standard on all new grand cherokees.
skyfly51 they dont have that on the new grand cherokees it has so ekind of shitty 4wd
Its not standard, the standard is actually command-trac which is a part time 4WD system, then selec-trac, quadra-trac, and quadra-drive.
@cbk982 no
Have 2 04 wjs I ordered them with select trac 100 times better than Quadra Drive
This is Garbage. On my 98 5.9 limited all 4 wheels seemed to always lock together. You cant beat tank-like traction. I wouldnt want any of the wheels just sitting there while the other spins and does all the work.
Sooo... my grandma's Jeep is bullshit all wheel drive?
You'd be surprised how capable they are.
Had it on my 99 grand. Hated it! I would rather have select track. pull shifter and in full time 4 wheel drive. This is a lazy mans 4 wheel drive.
Or just put you TJ in 4 low o_O
If you like to do burnouts than 247 is not for you.
I wouldn't want this on my car, i want to turn it off and on when i need it, i wouldn't want to be driving up a steep hill for my car to decide, oh well you have traction, you dont need four wheel drive, then turn off 4 wheel drive on me.
That's why u have a 4LO option.
It doesn't turn off four wheel drive. It just sends torque to the required wheel. The grand cherokee has constant four wheel drive.
michael9678727 its not constant. Its constant readiness 4wd but not constant 4wd. Constant 4wd would be both axels engaged and moving at all times.
turshin That's why It has a 4LO option I love It I wouldn't dare go to the lame ass 242 case.
Keith Leeman so you're saying 4LO commands all 4 wheels to move at all times with No speed sensor BS?
That's a real spiffy system for a permanent awd setup in a car but utterly useless garbage on a real jeep. When I put my older jeep into 4wd, all four spin at the same rate which makes for much more predictable drive qualities. When I need the traction to get out of 2' of snow, I need all four wheels getting power right away, not whenever the computer thinks I need certain tires to spin.
lol thats not how quadra drive works thats the basic understanding of how all ALL WHEEL drive cars/suvs function the only difference between your over rated jeep and a mercury mountaineer is the mercury uses abs sensors to apply the brakes to control the wheel spin reduction system, which in my ASE master certification opinion is a much more reliable and cheaper system to repair incase of damage :)
Quadra-drive uses the same transfer case as the quadra-trac system uses, the only difference is quadra-drive adds the limited slip front and rear differentials...and the quadra-trac system splits the power 48% front and 52% rear, so really its not in a 2WD mode ever, it just varies the torque depending on traction conditions and can send 100% of the torque to the front differential or rear differential if needed...the viscous coupler found in the transfer case many say lasts about 150k, I had 219k on my 96 Grand Cherokee when it started to fail which just turns your full time 4WD system into a part-time system LOL.
I assume you are talking about the newer Mountaineers? The older ones shared the same basic viscous coupler system like the Jeep quadra-trac. The newer mountaineers definitely use abs to help with traction.
Both systems work great until they wear out ;).
