View Full Version : wtf IS that noise?

90 XJ with a D35 rear
I have this freakin noise that's driving me crazy and can't isolate it. Hoping someone has heard similar and found it...
when starting and stopping - it's a hollow sounding tock noise. Not a metallic clunk like a bad ujoint (rear ujoint was new last fall) but almost a wooden sounding tock - kinda faint but definite.
I was thinking gear slop but why does it do it right when I come to a stop? - it should take up the slop as soon as I start decelerating....
I got under there last night and the rear diff seems kinda sloppy but I
ve seen much worse....
couldn't find anything else

i thaught you where putting in the 8.8?

I am but just haven't got around to it yet - too many other things keep taking up my time. If there is something wrong with my d35 then i'll just have more motivation to put in the 8.8
I was kinda planning to take the ins off the jeep in the fall and drive my audi while I do all the things to the jeep such as:
8.8 rear end, taurus elect fan, long arm lift, SYE and custom driveshaft....you know, all the fun stuff...
But in the meantime, I'm going on holidays to powell river in about 3 weeks and I want to make sure I get there...

Try changeing your rear diff fluid. I had a simalar problem on my 8.25 found that the fluid was no good it was making the same sort of noise as you described so i changed the fluid and put in the slip additive been fine ever since.

might have solved my own problem - I was poking around under there last night and looks like my slip joint at the t case is sloppier than it used to be. I guess the 3 1/2" lift is taking it's toll. I put some weight in the back and it doesn't make the noise anymore. I'll just keep it loaded up til I get all the suspension/drivetrain work done.

When I bought my XJ, both rear springs were broken right at the front of the springs at the curl, it made a bit of noise like that when I stopped I noticed it more. Hope it's not too serious man.[cheers]

hmmmm....I actually didn't check out the springs too well - although I did check the ubolts.... thanks, Joe.
I made my own bastard spring packs last year so I think they're pretty good but I will check them. thanks.
come to think of it, worn spring hanger bushings might make that noise.....but it hasn't done it since I put some weight in yesterday so might have already fixed it.
throw in a whole bottle of lucas oil staibalizer thatl shut it up.
