The whine you are referring to comes from the pinion depth as related to the ring gear. It happens on vehicles that have a damaged crush collar or a myriad of other problems in the diff assembly. This is only a basic explanation, as many other factors can also cause the typical whine on decel vs accel . Using bad ground up gears won't get you the result your looking for. Still great video guys.
The secret recipe is to add finely ground hot paprika, the Hungarian style. Also some Csabai sausages, roughly cut to pieces small enough just to fit through the hole. I would say about 0,7kg of paprika powder and 0,5 kg of Csabai sausages for that Lada differential. Also, no oil, but rather lard. About 1,3 kg should do the trick.
Hi Erik, I'll be in Hungary next week for a family trip in the region. I haven't been there since 1990 when the road was full of Trabants! How is driving there these days? Are the cops tricky and nasty or can you go as fast as you find safe like in Poland and Germany?

Paraffin is a great use for rear ends as there is nothing to stop up like a engine from the 70s from use of Castrol oil that had paraffin in it mabe even transmissions
Love you guys. THe crazy shit is excellent. Hope all goes well with current, dramas, send the best to all the crew from DOWN UNDER. Wish WE could have so much fun!! Thumbs up.
I remember an episode of The Andy Griffith Show where Barney Fife bought a worn out car from a little old lady who "only drove it to church on Sundays." One trick was to put sawdust in the rear end to quiet the noise for a few days, just long enough to sell it.
The dust should not be a dust...it should be something bit thicker... Have look for it in the pet shops. Than it will work... I know the story since my childhood and it real works.
God that was funny. That would have to be the worst sounding AND looking diff I think I've ever seen being put INTO a car. That noise. OMG there really was some carnage going on in that diff.
Holy smokes, that thing was absolutely annihilated, lol. Besides the ring and pinion missing chunks, I have to believe that the bearings are all pretty much hammered poo at this point as well. I don't think anything short of the hand of God would make that thing quiet again. Well, maybe the Doctor's sonic screwdriver could too, but even that would have a hard time. Hahahaha.... But whatever, it was a fun watch anyway. As it always is from this crew.
Vlad, great facial expressions during your initial test drive; you're looking a lot like Dr. Evil again! Voiceover guy, you're doing such a great job! I love the low-affect, Kermit the frog delivery! I'm quite curious. Your accent is clearly North American but your word choice makes me think you might be Canadian vs. USA-American. Am I right? What's your story? Please spill the beans! Stupid Idea #1: How nice would it sound if you guys were to randomly saw off several of the meshing gears? Fewer gears = less friction = less noise, right? Something tells me I may have this wrong. Stupid Idea #2: My wife's Lexus is a very quiet car. Your research in this video has me thinking that maybe I could make her car even quieter if I filled the differential with sawdust. It's a low-mileage, 2021 model - still under warranty. Would you agree that this is a terrifically good idea?
Also I don't know if I can Lucas, try 50% Lucas oil stabilizer with some powder graphite, mixed with some fine sawdust, it will work on a norm loud diff, yours is beyond control
it would be interesting to see is it possible to change rotation direction in a transmission. For example to put front mounted engine in a back of a VW beetle or Fiat 600.
My father said he blew a piston in a old car and back then money was not accessible as much as now but so what he did he said was took the wrist pin and rod and piston out then he said he put a price of log the size of the hole in then drove it in the cylinder then put it together and he said ya wouldn't know for a long enough .but that was before my time .but I'd really like you all to try it and see if it actually worked as he said .so give it a try and see how it acts he said he sold it and it sounded great and the person never knew and was driving it for years but ya try it yes?I really hope you do it would be interesting
On a carbureted engine with enough cylinders you can lose one like that and not have it be a big deal. I had a 3.0v6 in a Mercury Sable that had one cylinder with a head gasket failure leaking compression to atmosphere; it was usually a dead miss and a total waste of fuel. Because it was multi-port fuel injection, I disconnected the fuel injector on that cylinder and drove it quite happily on 5 for 40,000 miles or so. :) His solution simply deleted the cylinder entirely and would have a similar effect, though it would adversely affect engine balance because it's missing parts meant to be moving.
You did not put enough sawdust in and you should have used a more course grain sawdust. And try packing it full with graphite powder and heavy oil to make thick paste
I never heard about doing this to a differential, but I know the circle track racers around here would put sawdust in their transmission if it was slipping during a race.
Both can work in theory, graphite is a fairly good dry lubricant and lead babbit bearings have existed for centuries, although the lead needs some sort of oil in order to work properly
@@MAZEMIND is silica with alumina more abrasive than wood? well sparkplug ceramic is alumina and it can cut glass, so probably a tiny bit more abrasive
bad whine without sawdust, Grease or banana added is away a good check for when buying use cars maybe the Lada dift is too far gone. I am sure the diff will crush the lead shot verry well
the sawdust and lead powder / granulate leave a layer on the teeth and basicly muffles / deadends the noise created by the ringing of the steel it should work some but whont solve the actual problem
i remember when my differential exploded on the way to work in my chevy Colorado. it made this horrible noise and then the rear wheels locked up goin 50 mph. terrifying shit and cost me 4.5K.
Hi Garage 54 team. Can you make experiment and spray gasoline vapour in to the intake manifold of diesel engine? It's possible high revs and engine cannot shut down. So it's pretty dangerous experiment.
@@kinsmart7294 Well yea I can see it move, but I'm curious how it functions during normal use on a -40 degree day. Does it only open partially? Or does it open and close over and over and over etc.
I test drivetrain components for a living, I can tell you for a fact that a diff will chew up anything and everything including itself when given enough torque.
@@forrestcarroll9350 true. My pinion bearing went and one of the bearings came out along with part of the retainer... Sounded like a shotgun went off. No evidence of the pieces when I got home.ground up. When rebuilding, I tried to use denim doubled over a few times to jam the gears while tightening the pinion nut... Yeah.. It grounded that up in a hurry.
Sawdust In the gearbox used to be a common bodge, I think I just made the synchromesh work better in a worn gearbox, but only long enough to sell it lol
Pushing a pair of nylon tights in was supposed to be another bodge along these lines. They may have worked well enough to quieten it down so it could be sold.
Same here, but I also wanted them to pop the diff out so we could see if the lead had started to coat the gears, or if it had just mulched down to thicken the oil?
An old trick usually for automatic transmissions back in the 60's beforw selling the car. Unsuspecting buyers falls for the smooth running tranny for a few days before it breaks down
Thankfully it's pretty easy to drain the oil with sawdust inside and prove that it was a deliberate attempt to screw over the new owner in front of the court.
I was really hoping to see the diff. taken apart to see where the lead ended up.... too bad there was no transparant cover; maybe could have seen what happened right after start up. Great video still.
saw dust is much safer then powdered lead which could cause lead poisoning if it leaked out and got into a person no one's ever gotten saw dust poisoning🤣
Admittedly I took lead foil and ran it through a coffee grinder and packed the differential of my own ural motorcycle combined with grease to quiet it down for a few hundred kilometers to get where I needed. It worked like magic. I’ve heard of transmissions and differentials packed with sawdust. I did not know the lead trick was common. I thought I was clever at the time.
Yeah lets put saw dust or powdered lead in a transmission. U do realize a manual is a gearbox? Go head n dump stupid shit in a automatic n see what happens.
Yo should try that Xado stuff. Used one in my transmission when it was whining and it did absolutely nothing. Would be interesting to see an in depth, unbiased review of their products.
I can confirm that the banana and it's peel worked in my case. In 1970 I worked for a small construction company (3 workers plus owner). We had an early 60s Chevy pickup with a bad whine. The boss had me drain the rear end and add the peel of a one banana. Then mash up banana with a fork in the drained oil and use it to refill the diff. He had me use the truck for 2 days it went completely quiet. Then he sold it. He told me this would only work for a couple hundred miles. He said after that the oil/banana mix would turn into something that looked like black Jell-O sticking to the inside rear end housing and rear end was trashed.
Very efficient way to sicken, kill, or injure anyone that dares to tailgate you or stand around the vehicle after a drive. Mercury vapor is terrifyingly deadly. Fields metal might be a better bet, but damn would that be expensive!
I had a noisy 4.11 gearset in a Ford 9 inch and heard about the banana peel trick. So, I ground up a banana peel and stuffed it into the fill hole. After about 50 miles, the whine was gone! Now, I forget about doing this as years passed and destroyed it at the track. When I dropped the 3rd member, the smell was HORRIBLE as I was draining liquified rotten banana juice.
I like it that they can take cars out on to the road in various states of repair and registration in a relaxed state, rather than be paranoid about giving thug cops an excuse to send a large fine and loss of demerit points your way, as Australian drivers are accustomed to.
CV joint grease as top up instead of the oil does work with the beginnings of the whine. Did that and after 100 000 km the noise was still gone from the gearbox.
That’s what I was literally just thinking‘cause the sawdust only job is to thicken up the oil so I was thinking about packing it with like bearing grease or something like that
When they showed the undercarriage I was 100% expecting it to explode on the street. I was riding with one of my uncle's on the way to the scrap yard with about a 5000~ pound load of scrap metal, and literally a few hundred yards from the weighing scales just inside the yard. The differential exploded going around a bend just before the straight away to the yard. Then not even a month of being repaired, the transmission completely gave out at. You guessed it, the scrap yard. Where a big semi rig pulled him out of the way on the side of the road
I had a suuuuper rusty 300k mile truck with a terribly leaky power steering rack. It wouldn't hold fluid at all (it leaked out of the racks input shaft) I drove it around empty most of the time and muscled the wheel so I didn't have oil leaking all over my driveway... but before I traded it in (for scrap value, I just wanted to transfer the plates) I tried putting sawdust in the fluid to see if it would clog the leak. I put a few quarts of sawdust fluid in (3 tsp per qt of fine sawdust, and after it leaked enough out the leak slowed down dramatically! It went from emptying the res in 10 miles, to lasting a week! 😂
You need to add a few bananas to the sawdust/gear oil mix. A bit of grease from the grease gun is a must. This works fairly well in getting things quiet.
You guys did this all wrong, or. Started at the wrong end of the spectrum. This diff with shit gears would never survive due to being set up improperly. You need a unit that’s just outside of tolerable wear limits, that’s where saw dust work. Unfortunately the unit you tested on was an unrealistic application for this theory
The whine you are referring to comes from the pinion depth as related to the ring gear. It happens on vehicles that have a damaged crush collar or a myriad of other problems in the diff assembly. This is only a basic explanation, as many other factors can also cause the typical whine on decel vs accel . Using bad ground up gears won't get you the result your looking for. Still great video guys.
My thoughts as well.
This is pretty much what I was thinking, their diff is too far gone for this to work.
A worn pinion bearing will make a whine at speed too.
Could have better results if they have set the backlash on the pinion first,probably
It was a good video nonetheless!

I heard the same
Wow really. Lol i love old mechanics they always have something up the sleeve.
My dad told me about that as well. Would be cool if they try it out
++ used that in my jeep but just few weeks then sound came back again
I bought a fiat cinquecento that had banna in gear box put in prob to sell it
I think this story goes back to the days before they were using hypoid gears in differentials. Like when diffs still used straight cut gears.
Heavier trucks and buses often use diff gears with less angle meaning that they have some kind of audible humming but no grinding like the shot diff.
I've heard of using sawdust, bananas, straight STP, or motor honey.
I've tried STP, had to insert it with a spoon to the diff lol. Noise was slightly reduced but not gone.
I've seen an African semitruck have its differential filled with bananas to help it since it was failing. It actually worked.
Paraffin is a great use for rear ends as there is nothing to stop up like a engine from the 70s from use of Castrol oil that had paraffin in it mabe even transmissions

Of course it's gonna whine if you don't setup the gear pattern from pinion to crown gear so amount of sawdust will shut that up!
wonder what molten lead would do fill it and spin it up before it solidifies
Heck,I saw this in an Andy griffin episode

This is one of the old used car tricks …
Sawdust in the diff and banana skins in the gearbox

Sawdust and Fishoil

You need to add a few bananas to the sawdust/gear oil mix. A bit of grease from the grease gun is a must. This works fairly well in getting things quiet.
Then sell the car.
😂😂😂😂😂😂 well said good sir
You guys did this all wrong, or. Started at the wrong end of the spectrum. This diff with shit gears would never survive due to being set up improperly. You need a unit that’s just outside of tolerable wear limits, that’s where saw dust work. Unfortunately the unit you tested on was an unrealistic application for this theory
As long as it whines it's working when the whine stops then you have to start worrying
Dishonest car sellers have been using techniques like this for years to make dying rattle traps sound better than they were.
Using a diff that is completely wasted is the issue. If it was just a whiner and added stuff it might help but that thing is horrendous to begin with.
