I have a 99 2 Door with push button 4x4. Every Chevy I’ve ever seen leaked out of the transfer case.
I’ve gone down the rabbit hole trying to figure out what’s going on. The usual fix is people replace the seal where the slip yoke enters the transfer case.
Only to keep replacing it. Others have figured out to try and make sure the plug in the slip yoke isn’t leaking. Still only to be disappointed.
What I recall from 20 years ago is that what fixed mine back then was replacing an o-ring on the transfer case output shaft.
Someone a friend knew did it, so I don’t recall exactly how to do it & can’t find a YouTube video on it.
I’m sure I could figure it out, I don’t remember it being difficult at all.
Pull drive shaft, remove tail housing, not sure after that.
What I’m also not sure of is what o-ring to buy.
My plan is to replace the o-ring, replace the seal on the tail housing, and check the yoke plug.
Just curious if anyone knows what o-ring to get & if they have any specific advice on the job I should know ahead of time.
Thanks.
