Well I did some searching but because my symptoms are really hard to explain (in google language) I am going to hit up the folks here.
This weekend I put my 96 ZJ (4.0 Laredo) in reverse to back out of a parking space and "thunk", it just came to a stop. I thought I actually hit something. Got out and checked nothing was back there. I put it in drive and pulled back into my space, no problem. Back to reverse no problem and drove it home (30 miles at highways speeds). This morning I was heading into work (cold out 28 degrees) back down my driveway (also I park on an incline and use my parking brake to relieve stress on tranny/tcase/drive shafts etc.) No worries there, put it into drive and it made some kind of weird metal-on-metal "sqeak/squeal". It definitely sounds like its coming from the rear end.
As I jump on the highway I begin to hear more noise (from the rear) a sort of hum or whirrr under stress (climbing up a hill at 60mph), then at times I would hear like a "chirp chirp chirp" then it would stop. Got to work and parked it and got a ride home.
No codes btw, my daily driver, no major wheeling or mods done. Bone stock.
So my initial thoughts:
- Drive line u joint at the diff?
- Would a u-joint stop me cold in reverse? Could they bind up that bad and still get me home?
- Low or no diff fluid?
- Bad wheel bearing?
- Totally fudged up rear end...grr?
- Eff'd up t-case or something more mid ship/tranny etc.?
Any idears? Education helps too! Thanks guys! If you are ever in Shelton, WA I got a cold one for 'ya.
