Gents,
With the risk of being repeated, I would like to ask your opinion, on a strange vibration which has developed on my truck and I can't find a solution for. I am not sure if you would characterise it as "death wobble" or something else, so please bear with me.
Here are the symptoms:
When I cross a small poth hole, nothing big, maybe the sewer covers which are not level with the road, with one wheel going into it, I can feel a strange vibration on the steering wheel. I took the time to look at the driver's wheel while driving, and what I noticed is a wierd oscillation as if some one is turning the wheel left and right in a relatively rapid fashion. This same motion can be seen sometimes, even as I am driving over uneven road. The oscillation stops after a couple of repeats and does not escalate to something causing you to .... in your pants. However, it is annoying. Please notice that I have absolutely no vibration if I cross a bump, which makes both wheels to move, like a speed bump.
Here is the details of the truck:
1984 XJ, 2.5 lt with manual and 207. Lift is around 5.5" with Rusty's 4.5" kit, including less than a year old:
- lower fixed control arms
- adjustable uppers
- track bar with heavy duty bushing end and frame mount, very tightly bolted.
- steering stabilizer
- Bilstein shocks (brand new, the same thing happened with the one-month old OME shocks I had before)
- steering box is not new, but in very good condition
Alignment details:
- all TREs are tight, no play noticed by the alignment people, same with ball joints, same with the bearings
- Caster is at 6.5 degrees, a bit more on the left than on the right side
- Toe-in is zero or very very little positive
- front axle is absolutely centered with the rear
- all bushings are tight, no decernible play athe the control arm mounts
Any thoughts would be sincerely appreciated, as I do not know what to do from now on.
Kind regards
