Advice/suggestions on Pinion replacement

677 Views 8 Replies 6 Participants Last post by  JCRocks
Went to leave for work yesterday and felt a nice clunk/crunch about a block away from my house.... managed to get it home with an occasional terrible sound that seemed to be coming from the left rear tire... Put the jeep up on jack stands and rotated back tire to find alot of crunchy slop at a certain point during rotation. Pulled the diff cover to find chunks of metal in the housing about pea size on down... ring didn't appear to be missing any metal....

So... it has to be the pinion right?

Any imput would be great.... thanks, Don

Get a flash light and shine it inside watching the pinion spin. I would guess locker before pinion.
could be the shaft??

This might be a dumb question but...Can the locker just go without being locked?

I will try to see the pinion w/ a flashlight when I get home from wk....


** Also forgot to mention: when I had the wife drive it in a circle in front of my house the left rear tire would skip/lock slightly when turning hard left?
I would bet it is the stock locker. Mine blew the same when I made a 10mph 90degree right hand turn.

Yes. Check the helical gears inside the locker.

Man.... that's not what I wanted to hear...... did you go ARB?

**edited spelling
Same thing about 3 months ago. Upgraded to the ARB and 5.13s while I was at it.

Yes
Does it sound like this? See video

I pulled the carrier and found that I could not spin the pinion very well. It sticks in certain locations and takes a bit of force to get past those spots. I think the pinion bearings are shot in mine.

*** EDIT *** I just noticed you said there were chunks of metal. I did't have that so the issue may not be the same.
