97 F250 HD Rear Hub clunk

Hey guys,

Looks like rear end trouble, I have yet to take it apart, just looking for opinions.

Here's what I got:

I originally noticed a clunk from the rear while shifting from D to R and figured I was due for u joints, a couple weeks later I started to hear a slight squeal like worn brake shoes. A few days after this began I started hearing ticking especially on take off and taking corners. (still thought U joint)

I had my buddy shift from D to R while I took a look under the truck. When the truck is shifted while holding the brake I get a clunk from what appears to be the drivers side hub, but I also watch the shaft going into the diff and can see an unusual amount of play leading up to the clunk. I get slight vibration around 40-50mph also.

Either way this looks and sounds spendy.

So, what you guys think?

They make a crush sleeve eliminator. That is as long as your ring and pinion is not FUBAR

Re: 97 F250 HD Rear Hub clunk

Yeah i was ready about the eliminator. Do you know if the crush sleeve can just be replaced easily or does the pinion need to come out? I have maybe 10-15 miles on it since I noticed the noise....guess it could've been too late by them, hopefully wont need a new ring and pinion.

crush sleave goes in behind seal. but it cant just be replaced. It needs to be crushed to the correct amount, back lash checked, ........etc

Re: 97 F250 HD Rear Hub clunk

Well my truck is going in this Wednesday, I dont have time to rebuild the diff myself. I'd probably save $500+ in labor though. The worst part about this is that I'll be trailering my truck behind a duramax, ouch. I'll update with whatever they find.

Well well well...I guess I got excited for nothing. The rear end is perfect. The u joints were shot. I replaced both ends on the drive shaft, the roller bearings rusted solid and I actually had a broken lobe on the rear; lucky it didn't drop out on the road.
