So i've dealt with front end clunks and clanks before, and can usually track them down, but this time, I'm at a loss.
Here's the specs on my XJ's d30 that I just swapped in last weekend:
So it drives very nice, with no vibes or anything from the front end. Everything is torqued down nice and tight. The inner track bar hole is wallowed out, but the bolt is cranked down enough that it doesn't move, so that's out. The knuckles are definitely sitting tight on the ball joints, there's no vertical play at all in them. All 3 control arms are torqued down nice and tight.
The steering was installed less than a year ago, and all the joints are tight. The trackbar johnny joint was rebuilt 6 months ago and is tight, as is the axle end bushing. One of the control arm joints was taken apart and regreased when we did the axle swap, and the rest were taken apart and greased individually in Sept..
Honestly, it sounds like loose shock mounts. In fact, it sounds exactly like the shock bolts are loose, but they are not. The clunking doesn't come when turning, only when going over bumps, and from both sides.
This noise didn't arrive until I did the axle swap. I've taken the front end apart 2 times since I installed the axle 5 days ago, and just can not find anything loose.
So what do you think it could be?
My next idea is to pull the shocks and go for a ride and see if that eliminates the noise, but I'd seriously doubt it, and I'm out of ideas. My thinking for this is that these shocks were intended for the rear of an XJ, and i guess they may be unhappy with the added weight of the front end.
Here's the specs on my XJ's d30 that I just swapped in last weekend:
- New Spicer Ball Joints, uppers and lowers
- New SKS unit bearings
- Relatively new u-joints in the axle shafts(they're fine)
- Used 4.10 R&P w/ open carrier and complete rebuild kit professionally installed
- JKS adjustable track bar
- JCR 1-ton steering w/ no stabilizer.
- Used 5.5" RE Coils
- Brand new Rough Country shocks(they're the proper length)
- Rock Krawler 3-link
