So my Jeep seems to have a Whine at about 60 mph under load, but also coasting... Im thinking I need to get my Diffs looked at.

After looking on JF, it looks like I may have a bad Ring and Pinion but I need to take it to someone who knows what the heck is going on... Anybody have experience with a Diff whine?

This feels expensive...

ONLY with a '79 Bronco. Damn thing had just 13 teeth left on a 39 tooth ring gear, but she was still rolling when I drove it into the shop! :eek:

Look on the bright side - if it's going bad, now's the PERFECT time to go to those 5.13's, in anticipation of your 9" lift & 40" M/T's! :cool:

LOL yeah right.. The more I search the more I am thinking Pinion Bearing.

Guess my tax return wont be going to a superchips after all...

When was it last serviced?? Probably pinion bearing, grab your rear drive shaft and see if you have any play horizontally or vertically

maybe 20k ago? Its due I know...

I will check for play today. I have a buddy that is offering to help with the repair so thats good. Where in the world can I buy the Pinion Bearing for a QDII - dealer only?

I'd say it's a bearing, not the actual ring and pinion

Talked to a friend, he said usually when the bearing goes out, fluid would be leaking... is that always the case? I dont think I have fluid leaking from either front or rear pumpkin

I recently purchased a junk yard QDII FRONT axle assembly. I purchased an overhaul kit from yukon gear. Everything came out really well. Not sure if you can purchase individual bearings and races from them but it's worth a shot to ask them.

Thanks dude! I think an overhaul kit is what I need anyways. I will look them up.

I looked some online but everything I was seeing other places after I put in my vehicle info was showing D44 stuff.

Edit - I think I found the info I needed

Chrysler 8.25" '05 & up. This version of the 8.25" uses metric ring gear bolts. The C213R is an open differential. The C213RE has a factory electronic locker.
