Hi, I have a 93 Suburban 5.7l, 4L60E
I came back after letting the truck sit for 3 weeks and there was large puddle under the tail shaft. I could see drips on the universal joint.
I normally drive the truck every 1 or 2 weeks to hardware store, etc. and I've never seen drips from tail shaft seal. I occasionally add some tranny fluid so it could be leaking when driving but I don't notice. I put cardboard under and saw it was continuing to drip slowly.
I started truck, moved it forward 5 inches and no more dripping even after a few days.
Two questions
1) Is replacing tail shaft seal as easy as removing drive shaft, prying out the seal and tapping in another?
2) Curious as to why the apparent intermittent dripping. Is this just the fact I have a bad real seal and I let it sit so long this time that fluid drained out of torque converter and raised the level to where it could get to rear seal? or could there be some weird rotational position thing where it leaks at some points and not others? If so - that would be concerning, I'd think as something would likely be workout inside...?
Thanks!
