Guys,
I've got a vibration on my 99 XJ 4.0 automatic that is finally bugging me enough for me to chase it. It's been there for quite about 30k but is now getting a little worse.
It is a "speed specific" vibration. It ONLY happens between 55-60 mph, never happens below those speeds and never happens above those speeds. It happens on acceleration and when coasting.
It is pretty noticeable in the steering wheel and heck, you can even see the passenger seat shake a bit when it happens.
HERE ARE THE THINGS IT IS NOT.....
It is NOT death wobble. I had that malady a while back and fixed it with replacing all the ball joints, steering stabilizer (not the root cause of DW but needed replacing) and an alignment. This vibe shares none of the extensive symptoms of death wobble.
It is also NOT wheel and or tire related. I have completely exhausted that possibility. Tires have recently been replaced and vibe continues. Wheels have been verified by the best of balancing equipment (twice).
Now that I've completely eliminated wheels/tires, I need to look elsewhere.
I've done a thorough inspection of all front end and steering components and everything is pretty tight but hard to know for sure with that. 140k on the vehicle.
I'm wondering if I shouldn't remove the front driveshaft for starters and see if that eliminates the vibe.
Anybody seen this on yours or have ideas on things to try/check?
Thanks guys......
