Title: Axle seals
Post by: GTRS Fiero on November 03, 2020, 05:19:10 pm: Since I'm going to replace the axles, and I think one seal is leaking, I want to replace the axle seals. Finding the seals is proving more difficult than expected. The part shows, for several transmissions, then says it won't fit my transmission.

I may possibly have found a right side axle seal.

Hopefully, they're correct. The passenger axle was possibly leaking, so this should be the right one.

Post by: GTRS Fiero on November 09, 2020, 07:03:11 pm: They're red and green, so they must fit! ;)

Post by: scottb on November 09, 2020, 07:10:08 pm: I would recommend a coating of gorilla snot (3m super weatherstrip adhesive) before installing. That will help to seal any potential leaks in the case. A hint is to get the adhesive cold before applying, makes it less stringy.

Post by: GTRS Fiero on November 09, 2020, 07:10:40 pm: It may take me that long to get them installed. If you can guarantee that the red and green seals, if installed next month, will guaranteed fit, I can guarantee it will be next month when they get installed. :D

Good idea.

Post by: GTRS Fiero on November 09, 2020, 07:19:32 pm: Lube the axle shaft? Or just the rubber at the joints?
Title: Re: Axle seals
Post by: Wreck It Ralph on November 09, 2020, 07:23:37 pm: Shaft and rubber. Prevents Tears in the rubber. You can also just mix petroleum jelly and transmission fluid. Slick as ice.

I've always used 3m super weatherstrip adhesive........ FYI, monkey snot is used on piping systems in the US Navy

Post by: GTRS Fiero on November 10, 2020, 05:48:32 pm: On the trip down there, I lost a quart of transmission fluid. I knew it was leaking a bit at the right axle seal, and certainly, there were a few drops, from time to time. When the axle seal comes out, I want to see why it was leaking.
Title: Re: Axle seals
Post by: Wreck It Ralph on November 10, 2020, 05:55:44 pm: Old rubber, shaky axle, bad differential. Or a combination
Title: Re: Axle seals
Post by: GTRS Fiero on November 10, 2020, 06:01:45 pm: Supposedly, the axle seals were replaced.
Title: Re: Axle seals
Post by: Wreck It Ralph on November 10, 2020, 06:48:11 pm: Hmmm.... have you checked for play in the cv axle? Or wrong seal or bad installer or didn’t actually do it.
Title: Re: Axle seals
Post by: GTRS Fiero on November 10, 2020, 06:50:27 pm: All TBD when axle comes out. The axle had been tight.

Post by: Wreck It Ralph on November 10, 2020, 06:58:37 pm: He may have cut the seal on install. I’ve done that way too many times when I did trannys for a living.
Title: Re: Axle seals
Post by: GTRS Fiero on November 10, 2020, 06:59:34 pm: Well, the leaks are slowly getting fixed. Hopefully, this fixes the last leak.
Title: Re: Axle seals
Post by: GTRS Fiero on November 16, 2020, 05:38:19 pm: The axle seals are in, and they fit. Time will tell about the leak.
Title: Re: Axle seals
Post by: GTRS Fiero on November 19, 2020, 05:48:05 pm: The leak had been a few drops, occasionally. 3 days, no leak.
Title: Re: Axle seals
Post by: GTRS Fiero on November 28, 2020, 09:55:10 pm: Great. It's leaking on the left side, now.
Title: Re: Axle seals
Post by: GTRS Fiero on February 14, 2021, 10:14:49 am: The problem ended up being a bad spot on the transmission pan. That gasket was replaced, and the bad spot fixed.
