Apparently it is a manual XJR6:


see the subframe and upper bush move around, i think i see the vee mount lift as well.

 

Yes, but what amount of movement is normal/benign?

your guess == my guess

of course it is possible to do videos of both sides
and if one is worse than the other, then its food
for thought.

 

AT least the Go-Pro didn't fall off!

 

Let me have another stab at this

If the bush moves more than the amount needed to change a
the wheel alignment by 'x' degrees where 'x' would be unacceptable
error in the static alignment ... there is potentially a problem.

Of course, vee mounts lifting would be a Bad Thing(tm).

 

I found the video fascinating. Much more interesting than watching say
Jeremy Clarkson smoke tires around a track.

Especially since I discovered what seems to be a worn upper right balljoint
last night while preparing for a pad slap.

The tire can be rocked at the top by 1-2mm but not at the bottom
or sides. A finger spanning the hub to upper control arm joint area
can detect movement at the joint. Through a work glove.

Hmmm ....

 

I would occasionally get tramlining on certain road conditions but it stopped when I changed all four tyres, incidentally if any ones interested I had four "Landsail" tyres fitted they are a midpriced Chinese tyre and despite my initial concerns regarding quality they have been just fine and after seven months of use I've no complaints.

 

I hate to sound dumb. But what does the term tramlining mean????

 

Tramlining is when the car appears to be following a groove in the road and not responding to small steering corrections. If you have ever driven on a street with streetcar (tram) tracks you will notice the unpleasant sensation immediately.

I had that problem with my Z3 when I bought it, but new tires fixed it Worn suspension and steering bushes can often result in the same sensation.

 

I would remove the cable tie from the hoses to the brakes - it is preventing free movement between the two ends, effectively creating two shorter lengths,and so causing more stress/bending on the hoses, which will fail sooner.
