Since we are going to be swapping the GMC Sierra 4.3 V6 to a 5.3 V8 I decided the old rear end was not going to work. The old rear end was a open differential with a 3.42 gear ratio. I wanted a posi rear and my parts truck actually had a good G80 locking diff with a 3.73 gear ratio. In Todays video I show you how to pull it out of a donor truck, clean up and swap to another. In the process I also change the rear differential fluid in the g80 and upgrade to a ta rear end cover. The TA or rear end cover is WAY more sturdy and looks SO MUCH better. This process is the Same on GMC Sierra and Chevy Silverado.

The more videos I watch it still amazes me how similar we work as far as material and parts and meticulous methods. Things always cost me more and take longer as I’m just like you doing it right the first time
It does take me longer than others
"YET" love the sound of that!! can't wait to see what you have in mind. 👍
Lol
Yesss more sierra content
Yep yep
That time was well spent, do it clean and right the first time. Can’t wait for what’s coming down the line on all the projects.
Thank you. It's slow and steady progress
TWA Motorsports I hear that! I got my 03 Yukon Denali a couple months ago and it’s just now ready for paint. Got all the big projects and repairs out of the way first. It takes time but it’s worth it.
Absolutely
Hell yeah - great swap and saving money!! Part out that Silverado and save what you need for future projects!!
That is the plan.
Good choice of cover... they look real nice/beefy!
Excellent video! You covered everything I needed to know in plain clear English. Very helpful, thanks!
Thank you. Glad I could help
Awesome job Mr, TWA
i just changed the pulley for the steering pump and so a new rack and pinion on my TA. And capped the oem cooler , but i installed an external steering cooler behind the plastic dam under the radiator. Hope i get to drive it next week
👍
Your a good mechanic on your vehicles. I used to be a ASE mechanic before I joined the Navy. I still turn wrenches on my vehicles but I don't do it for living anymore. I'm an engineer at GE. I do side work on my friends vehicles still.
I don't want to do it for a living but like to tinker
I’m about to replace my rear end this weekend, seems pretty simple. Thanks for the video!
Thank you. It's not a bad swap at all
Great job as usual Travis. I love the truck content. Keep up the awesome videos.
Thank you Larry.
Very detailed work looks great, I'm re-watching the swap series
Thank you. It was a process
@@TWAMotorsports I can't see any comments on ur vids newer then 6 months ago? The newest comment button doesn't work anymore for me on any channels I watch, it's never done that before, kinda sucks
That's really weird
The diff cover looks great.
Thank you
Great video! I need to do this and I've never done it, so u helped a lot.
Thank you. Glad I could help
Another great how-to😎
Thanks for keeping them coming!
Thank you
looking forward to the LS swap i have 4.3 chevy looking into doing the same
I'm excited to do it
Hell of a good job, truck is turning our very nice!
Thank you
Man you always make your stuff look nice. Now you got me wanting to do the same to the underside of my truck. Looking forward to the burnout 😁
Thank you. Oh burnouts will happen lol
@@TWAMotorsports .... With that V8 I'm sure it will do good burnouts.
It better lol
Great job and another great video. And, don't ever feel bad about taking more time to do it right. Love that you did that. And, of you hurried it, you would have more time arguing with the "keyboard warriors." Ha ha! Again, good job!
Thank you. Yeah projects are getting harder these days lol
That looks awesome Travis! I did this to my 04 rear with spray paint products and so far so good. U want to use por15 on my Duramax chassis and frame though. I thought of buying the TA diff cover for my Trans Am to preserve that rear end lol. As always enjoy the videos!
Thank you. I will be using one on my ta also
As usual a Great video 👌😊 so much information I learn so much for you thanks for for all of your hard work and remember keep God first and everything else last 🙏😇
Thank you very much
Brave working/cleaning so close to the Vette!
I'm pretty careful
Your videos are so underrated and deserve more views
Thank you. Tell 100 people lol
The videos keep getting better and better! Keep it up loving the gm content 👌
Thank you sir.
That diff cover and paint looks good.
Thank you Dustin
Love when you jam lot of a process in one video
Its killing me to keep up
NICEEEE !!! Like how the truck is turning out
Thank you
I heard flip kit and you got my sub 🤣🤣
Lol
Really liked this vid! Great content.
Thank you
Really enjoying the content. 👍 👀 forward to more.
Thank you
Nice video bro what year was that truck you took rear ended out. And what were those numbers again that you look in glove box
Think it was a 2001
Put a full Denali interior on the green truck
Some interior changes are coming
Loved it! Thats right, Take your time!
Thank you
This diff is better then the spring loaded diffs the block style for lock up is better for longevity and before you worry about differential transmission needs to be built first before anything the 4L60 Is super weak and doesn’t like anything over 6000 rpm shifts so if you plan on a camshaft or stall converter the transmission needs building or don’t shift past 5900
Yeah I know the transmission will be on borrowed time
Awesome... Keep the truck content coming!!!
Thank you
were axles standard based on certain model trucks? or could buyers upgrade? seems like the GT4 G80 would be a rare option except on HD 8 lug trucks
Not sure
Excellent video.
Thank you
So much help ❤❤❤
Thank you. Glad it helped
Literally here at the junkyard watching you're video again from last night 💯💯
@markcriollo5377 lol
I would be interested in hearing about what you do about correcting the speedometer after tire and or gear swaps. I put 20s on my tahoe and the speedo is off about 5 mph.
That will be done with hp tuners when the motor goes in.
Nice rig!
Thank you
Great video
Thank you
I did a LS swap also and my donor truck is a 2001 Chevy what was the numbers again that are in the glove box
3.73s. Can't remember code
Appreciate the insight
Hopefully it helps
1500 chevy silverado 2006 2wd WhatsApp part my truck fit can You
Help me please
None of what you asked makes sense to me
Hey man you probably mentioned in somewhere in the video.
Will a z71 rear end fit a rwd?
Yes
Im waiting for that swap sounds good 👌
I'm ready
Perfect timing on this video. Was thinking about doing one of those covers for my LT1 Camaro. Probably worth the $150 for a little bit of protection on these rather weak rear ends, no?
Absolutely worth it for added strength
What added Strength it just holds fluid if you want strength and protection better gears and axles will get you right a diff cover WILL NOT this guy is delusional it’s still a GM stock rear end.
Maybe so
love your content!!! Absolutely love it.
Thank you
are we doing warm over mods first or v8 in truck then we warm it over? G80 isnt bad for a street truck. i think the other is the G86 is the LSD which I think is a helical gear style? Im still a fan of 4.8 pistons 706 heads and a hot truck v2 cam with TBSS intake. pick your headers and some side exit exhaust
Several things to do honestly. Just a cam and headers for now.
G86 is a Eaton clutch plate LSD.
Travis, did you have the computer flashed for the different gear ratio? I assume you used your HP Tuners to make the change. Talked to my guy that does tunes and he said its a simple change in the computer. I was just wondering if the trans felt ok before you flashed it. I bought a G80 rear end that I am going to go through before I do the swap on my sons truck
Yes I did make those changes with hp tuners but before changing it all felt good.
I was just wondering if it would be ok to drive about 35 miles or so to get it flashed or if I would need to trailer it. Thats why I asked if the trans was ok if you drove it before the reflash @@TWAMotorsports
@brandon.buchanan81 you can drive it
Hi Travis the number part from your new differential is 2590268? I just start to do a swap in the rear axle but i dont have RPO codes in the glove box 😅
I have no idea on complete rear part number
Think I missed part about why swap was being done? Better gear ratio? Posi unit?
All of the above before the V8 goes in
Awesome bro I did the same on my 05 crewcab 373 is the way to go. What size of tire are you running on those 20
Thank you. 245/45
Hey bro I got a question I put some lowering spindles on my 2012 Chevy Tahoe but didn't drop it u know why ?
Already had them
No I bought them from summit racing ..
@@adolfosandoval7523 I mean you took off ones that had been installed before.
Yes I swap them with the two inch drop spindles n honestly I don't see no difference...u think I might need to change the shock's or something?
Where does the rubber hose that connects to the rearend go ..its.like 4ft long and looks to be a vent hose
It is a vent. Clips to frame
Looking for help. I own a 1974 Buick Electra 225 2 door custom with a 12 bolt rear end. I want to convert the rear end to disc brakes and can’t find a conversion kit. I’ve heard a Truck rear end would work. Any suggestions on a year that will convert?
I honestly don't know. Look up kore3 website
I don't know much about rear ends on the trucks but I am going to a 6.0 swap in the near future. Will I have to to a rear end swap with it also?
If it isn't at least a g80 which means positrack I would.
Doing a 6.0ls swap all refurbished every part brand new but they said when I get a 4180 I need to upgrade my rear ended plus ima add 4:10 gears so both my tires can spin is it worth it
👍
You could have put the gear oil in before you put the cover on, since you had it opening facing up. That way when your sealant dries, all you have to do is put the rear in back in. This will also test whether your front seal is good or not.
I could have. I put the gear oil in a few days later
In the 10 bolts with the fill plug high up on the pinion snout like this one, I put in ~2.5qts of lube.
Good info. Thank you
Great video bro keep it up!
Thank you
I know this video is old but Im hoping you get a chance to respond , did you have to get any type of tune to be able to run this swap?
No but shift points and speedo will be off if not.
Excellent, What mirrors are on that truck? I want to get rid of my elephant ears.
All parts on the truck are listed in video description
So would the rear end from a Tahoe fit my 1989 GMC Sierra? I have the 5.3 installed already just need a different rear end. Plus I wanted the disk brakes
No they are coil spring rear ends
Do an LED headlight & taillight conversion tutorial on the Sierra.
At some point I will.
Okay question, I have a 03 Silverado 1500 it’s a z71 with 3.73s will the guts out of a 94 2500 rear end with 3.73 posi trac work in my diff ?
It should
hey man i have a 06 sierra with the one tire fire with 3.42 gears and i wanna go to the junk yard and get a g80 to put in it i just have some questions does it just bolt right up including brake lines because i have drum and i’d be switching to disc. thank you
Yes it will bolt in and work. will need rear brake line possibly.
Did you have any issues with ride quality after the swap? I just swapped a G80 into my 05 z71, and the tires screech when I turn, and if Im turning into a parking space the truck gets kinda hesitant and doesn’t wanna move
No issues. You have a broken diff unfortunately
Hey man what are the torque specs for the driveshaft u joint 4 bolts that bolts it to the diff
15lb ft
Outstanding
Thank you
Do you have a list of possible donor disc brake rear ends that work on the 94 and older trucks? and how did you determine the gear ratio on the disc brake rear end?
I don't. Have to open the case to be sure on ratio unless original to the vehicle. Rpo codes in glove box should tell gear ratio if it hasn't been messed with.
@@TWAMotorsports thanks , I appreciate the reply …
You're welcome
Travis, is there a benefit to do the rear end swap on the V6 if i don't want to do the v8 swap? Like I said on your last video I just got an 03 silverado v6 but I've noticed it has rear disk brakes. I thought only the 4x4 models had rear disk. Am I wrong? The thing sits up way to high and I'm assuming the previous owners did a complete 4x4 suspension swap.
Its only a 2wd. Im aiming on doing an SS clone thats why i got the 2003.
That all had disc brakes for a few years. Maybe some small benefits with a v6 but not a ton
I wana see more of the chevy truck 👍
You will
Did you have to calibrate the speedometer after gear swap
I will do that when I finish the motor swap.
I got a 99 2dr tahoe with a possible bad rear.I have the gt4 but without the g80 option.Can I swap a gt4 g80 to it with out any issues?
Yes. Not issues with doing that.
would this work with swapping rearends on a disc brake truck to one with drums? are the parking brake cables the same?
I believe they are the same
@@TWAMotorsports reason i ask is because i will be doing the swap from 03 extended cab with discs onto a 06 single cab with drums.
Should work
Did you have to set the pinion angle?
No. Preset in saddles
What year is the parts truck
2001
Purpose of the bolt and jam nut in the cover?
It's to tighten the bearing load caps. Keeps pressure on the bearing caps so they don't flex.
What differntial swap upgrade do you recommend for a 2005 tahoe
Maybe one from Denali
The question I have is "why?" I'm currently trying to figure out what diffs came with what since my newest purchase does the 1 wheel. Is there a way to figure out which axles have a LSD?
Generally the glove box has codes. If you see g80 it has posi rear
@@TWAMotorsports Isn't the G80 a locker though, not really a posi? From what I understand GM put some idiotic mechanism in there that only really engages the other wheel when the first one has already been spinning a certain amount of RPM's more that its counterpart.
G80 is a locker style but considered a positrac
What is up guys!
Or ladys I guess
yesss another vid🎉
👍😎
will a 2015 gmc sierra diff fit a 2006?
I'm not sure
Sik bro!!!👍🏽🔥💯 whatchu gunna do with that rear end? Cuz I need a disc rear end?
It will stay under the donor so I can move it around
TWA Motorsports 😩
Sorry
TWA Motorsports it's all good bro 😎
Will this ta diff cover fit on a 2010 1500?
Yes
what did you use to prep it ?
Nothing. Just scuffed
Great video 👍👍👍🙏🙏💯💯
Thank you
Why did you swap the rear end? What gear ratio?
Like I said in the video for a 3.73 and posi
I lowered my 95 chevy c1500 with a djm flip kit and the passenger rear tire sticks out more than the driver side any help with that or is that how the truck is. Can the axel move ?
I'm not a fan of the adjustment in djm flip kit. Not sure as I never use them
@@TWAMotorsports I’ve been reading online that chevy has one side sticking out more than the other not sure if its true but mine is thanks for your reply
I have never experienced this
How did you do to change from 8 to 6?
Do understand that question
Nice video,do you like to test a DIY scan tool ?
Thank you. I could try
@@TWAMotorsports OK,we have sent a email 4 days ago,please check it .Thank you
So did you already have rotors in the back or was it drums?
Discs already
@@TWAMotorsports would you happen to know what needs to be done for swapping from drums to rotors or is it a direct swap?
Direct swap. Plus new lines
@@TWAMotorsports so brake lines need to be switched out?
On the rearend
Nice
Thank you
I eat cereal out of those blue cups!
Lol
That POR 15 will turn gray is you don't add a top coat.
Only if exposed to uv light.
Don"t trust those bags or lines, throw the jackstands back under if you're crawling under it
It wouldn't hit if the lines leaked
What brand your drop and price on it ?
All parts listed in description
Were the gear ratios the same?
No
@@TWAMotorsports is there a downside to them not being the same? I have a 05 Silverado crew cab with drums and I want to convert to disc. I have a rear end off a 03 Silverado disc brake setup. I don’t trailer anything. Thank you.
I am a fan of disc
How can you tell what rear end has a g80
Code in glove box like I stated in the video or remove cover and look
Do you have the link for the TA differential cover?
In the description like always 👍
Thank you sir must be going blind I didn’t see it at first! Awesome content can’t wait for the White Silverado and WS6 content.
You're welcome. Hopefully I can keep up lol
You got this brotha! I’ve been watching since the beginning Quality has been steadily getting better i know it’s probably a lot harder trying to work on a car and video but you have a handle on that and make it look easy! Lol
Get the lube locker gasket. They are reusable 👍
I just discovered those the other day. Wish I would have know before I did this though.
Next time. They are so much easier and cleaner to use
@@gearheadwrenching9072 I'm sure of that.
