Good vibrations....
Hey all, as per title my XJ has some lovely vibes. Theyre pretty constant, but you can feel it through your ass badly at 75 and 100kmh. Would I be looking @ dshafts and unis? Also my wheels got balanced and aligned the other day.... any recommendations? all stock, new gearbox mount too (do I need to loosen this?)

Should I jack it up, chuck it in drive on stands and get it up to speed to see if it vibrates without the front driveshaft in the way ? Cheers .

I had the rear driveshaft out not long ago, the uni felt good. Can the front one cause similar issues?
Also I have messed with the gearbox mount. Does anyone know the distance between the TC and their bash plate?
Also as my diff is shit, could it be a worn pinion causing bad vibration?
Thanks.

did you mark & keep rear driveshaft in same orientation during R&R ?
apparently the trans space is ~1", mine is a bit less from age, needs replacing
I doubt a worn pinion bearing would cause vibration unless it was terminal, is there excessive freeplay...like 1/4"?..would be awful noisy
mine vibrates a bit at ~90-95kmph (it needs a wheel alignment)
the trackbar joints can be worn
I would start with the basics things

There's a lot of noise from the diff.
I had it up in the air the other day running in drive, the rear wheels looked to be not rotating on a solid axis. They looked like they were moving slightly off centre like both axles are bent. Unsure if this is the case... Is this normal?
All my driveshafts feel okay, didn't spend too much time down there as it burnt the shit outta my arm and took a heap of skin off
How do I check the suspension components?
Also I didn't line up the DS but can only spin one more rotation. I think it was correct as I just removed the uni joint on the diff end (the 4 bolts) but didn't pull it out of the DS.

I'm pretty sure it's the diff. I think the axles are bent.

Hey mate
Did you grab a wheel whilst it was up in the air to check for play in the wheel bearings. If they have gotten bad enough they will quickly wear through the thin hardening on the axle into the softer metal and you will possible get that appearance of the axle being bent.

Thanks mate! I definitely did. Didn't seem to be much movement if any which worried me even more. I have a new diff assembly on the way (second hander) with a 12 month warranty. Hopefully this will sort my XJ out quite well. Hope the LSD works still too. If not a rebuild on a traclok isn't that hard is it?
