Yup, gotta love that rotten chocolate milkshake in the diff carrier!
Found that myself!
Just one of those 'PO' things you have to take care of!
Thanks for all the suggestions. I didn't mean to hi-jack the thread, just pointing out what you can find when you start looking.
I actually did all that work last year. I slept with that thread on water-proofing (which I linked to above) under my pillow for a couple months to get the axle cleaned up. Excellent step-by-step instruction on how to tear-down and rebuild the axle.
A weekend job to do rotors and pads yielded a much longer journey to the center of my axle.
It ALWAYS happens, you start out to chance a $3 seal or 98¢ gasket, and wind up spending $500 and taking a MONTH to chase out what the PO did to things!
I start all my 'New Purchases' (New to ME!) with the basics,
Repacking wheel bearings, putting in new seals/gaskets, pulling the diff covers and having a clean up/inspection,
Pulling the old lubricant out of the transmission/transfer case and having a look at what comes out,
Tightening up the bolts that are still there, replacing the ones that are MIA,
Checking brakes, getting them working again,
General engine tune up, changing the coolant and flushing the radiator/block,
Replacing hoses and belts...
The stuff that EVERY neglected CJ has when you get it...
You know, I SHOULD just buy a new Jeep and get it over with, but I've worked on 'Junk' so long I wouldn't know how to act if SOMETHING wasn't broke or in need if IMMEDIATE ATTENTION!
