Xantia vibration at speed - alchemist
Hi everyone
I'm new to these forums, though I have been lurking about reading the odd topic here and there, mostly about xantia spheres, but I have yet to find a satisfactory answer to my problem, so I thought I'd post it and see if anyone can think of an answer..
I have an R(1998) Xantia LX TD 122k
Basically, I?m getting vibration at speed- the drive is fine until about 60, and then as I creep over 70 it gets progressively worse. I?ve had the wheels rebalanced, and checked the spheres, all four corners have a nice give in them. Rear 3 spheres replaced in feb this year, and the front 2 in august 05.
I also have an old xantia (the hydraulics were leaking gently for years and I just topped her up with lhm here and there, so eventually they broke badly) however, the car itself is fine, and I have new tyres on her and new spheres.. So I?ll be taking bits off her for later usage before scrapping her.. L(1994) 210k TD
Basically what do you guys think could be causing the vibration?
The guy who rebalanced my wheels said one looked a little wobbly (warped) on the balancing machine but to be honest it looked a minor wobble - this weekend I?m going take a wheel off the old xantia and switch to see if it is that which is causing the issue.
However, if that is not the cause what else is it? I?m getting tracking looked at tonight, but I don?t think it is that; and I have ruled out a wheel bearing as I know what they sound like and there is no associated noise with it. Just a regular vibration that makes the rear-view mirror shake and my bones go numb(!)
Any ideas? Thoughts?
cheers guys, looking forward to hearing from you

Possibly the right hand side driveshaft intermediate bearing. It's mounted on the rear of the engine.

Assuming that the drive shaft cv joints are ok.

It's not unknown for the wheels (alloy?) to buckle. Tends to be really noticeable at around 65/70 and fades away by about 90.
