How to fix a leaking left front axle seal, Chev/GM 4X4, part 2

How to fix a leaking left front axle seal, Chev/GM 4X4,  part 2

This is a followup video for a left front axle seal repair on a 2000 Suburban 4WD. This is the 8.25″ IFS front axle. If you are doing this for the first time you’ll also want to review that more complete video as well, shown here. https://youtu.be/X0wSjCZMBNE

In this video, lessons from the first repair 7 years ago are discussed, with a closer look at the front differential vent cap, that allows limited access to the front differential. The function and form of the threaded adjusters behind the vent cover is shown, designed to adjust ring gear backlash and carrier bearing preload.

For an excellent demonstration of how those threaded adjusters are used adjust front differential backlash in a front differential that is removed from the vehicle, Eric O from SouthMainAuto has a good video, here:https://youtu.be/Chu1Xi81PJI

For a really good professional rebuild demo on the 9.25 IFS, try this one https://youtu.be/ldqWZ3q2PF0 It goes into some details of what you can do if the stub shaft won’t come out, and they describe a special tool they designed and sell to remove the stub shaft after taking the diff off the truck.

For a more basic demonstration of how backlash is adjusted on the vehicle in a Chrysler limited slip rear differential, this video shows it pretty wellhttps://youtu.be/1ZAarOHmpD4

I remember back 7 years 🙂 mine was doing the same on my 02 2500hd but it was my fault for overfilling it so I check my manual and yes I filled it till it started to run back out and thats too high. Sure glad I didn't have to tear it apart. Cheers Dave .

Use a slide hammer ..

Discount Auto Repair says:

A lot of great tips .

george holmes says:

Put a pry bar behind it with some pressure and take a hammer and tap directly on the middle of the inner axle and it pops right out in a couple taps. Brother in law taught me that and it works like a charm every time

Archie White says:

Great videos Dave. Was looking for some guidance for a fix on a vehicle and thought I recognized you. This the same Dave that used to live in Lethbridge? If so, I hope all is well! Cheers, Archie.

Mr Vaulted says:

Stub axle , slide hammer , or regular hammer , tie some twine or line to an empty bolt hole, pull on it, steady pressure rotating axle hitting it, dead blow.

Great job , ENJOYED !!

Pedro Padilla says:

Very informative video my truck is starting to leak from that plastic vent deal thing. im gonna have replace the seal and everything.

James Hus says:

I took the stub axle out and used a slide hammer loaner from the local parts store. To use the slide hammer I made an extension out of some 1/2 threaded rod. I adapted the 5/8" NF thread to 1/2 NC by welding together a couple of nuts, 5/8 on one side and 1/2 on the other. I recently changed both front seals over the last few months and really appreciated your videos.

Informative video Dave and keep up the good work!

Napper – not a sponser
Seen a napper store in perth Australia had a chuckle

7 years ago, That's disgusting it should have lasted forever ha ha 😀
That little T tab looked too easy to break, i imagine a little heat would have made it less likely to snap.
But getting a tiny blowtorch to heat only the tab up would be hard to do.

Thomas Plewacki says:

If you ever get a definitive answer on the c clip/ axle removal please update.. I could never find the correct way except to drop the transfer case

SV Impavidus says:

Just wondering if the stub axle would come out easier with a slide hammer and rotation? Sail Safe mate. Ant, Cid & the pooch crew.

m ph says:

Nice. I did the right side on mine last year. Its leaking again, I thought I did everything properly. Oh well.

the GADGETS playlist says:

that's a fun job to begin with but extra fun crawling in there with a camera:)
well explained throughout, Dave

Ozzstar's Cars says:

It's nice to stop those pesky leaks, especially in this case. If that diff runs dry and let's loose it's going to be a big repair!
