Well, just after I put in the new axles something else popped up:

The noise only occurs when the clutch is engaged and under heavy load (gas pedal pushed about 3/4- the metal.) Under normal driving I get hardly a chatter. Yes, I know the best solution is to just not drive it like that. I'm just considering driving up in the mountains & climbing steep hills.

It's sort of a whirring sound. Kind of metallic too. It mostly sounds like it's coming from towards the mid-rear of the car. My first thought was something driveshaft related.

I went through and checked the front diff, tranny, transfer case & rear diff, all stocked full of fresh fluid. Right behind the transfer case though are signs of a leak, and I think it might be coming through a seal at the back (http://www.ncttora.com/fsm/1990-1995...r/oilseals.pdf) perhaps related to the rear companion flange.

This is as far as I can stab at what's goin on here.... anyone else have an idea?

 

Also, only seems to be after the car warms up.

 

Picked up some more free time to scrounge through the forums and found this: https://www.yotatech.com/forums/f116...14/index2.html

Sound exactly like what I'm looking at. Springs a couple questions. Sounds like this 4.88 gearing is the way to go. But, I don't know where to get it or even what exactly he meant there, is this the Ring and Pinion he's talking about?

Where's the write-up he's talking about?

 

It could very well be your differential dying. When was the last time you did a full tune up of the fluids?

Ring and pinion, yes. 4.88 or 4.88:1 gear ratio means for every ONE(1) time the ring gear rotates, the pinion rotates 4.88 times.

 

Well, I just picked it up about a week ago. I checked all the fluids as soon as the noise started up though (Thursday). Clean as a whistle, they were all as clear as gear oil gets.
