Will get it looked at when the snow and ice recede....

Both sides equal when pressed, and neither corner affects the opposite corner any more than the other one does when pressed, if you see what I mean. You might need to read that several times ;-) The unequal settling doesn't happen if the brakes are off. And it doesn't happen to the same degree once I've released the brakes and re-applied them, then put it into drive / back into neutral. So presumably some latent energy is being stored (like a coiled spring) at the point of stopping the car, until the brakes are released, at which point the energy is dispersed. Having just re-read the above, I'll be amazed if you can understand any of it. Time for bed.

Thanks, Tony. Managed to find some almost new D8Z's locally. Removed the Primacies from the front and replaced with D8Z's and the tramlining has disappeared! In addition, the ride is less harsh than the Primacies. So I'll keep the Primacies on the rear wheels until they wear out, but I don't know what I'll end up doing with the fronts when the D8Z's wear out... The ony remaining issue now is that when pulling up at traffic lights in Drive with the foot still on the brakes, when I then select Neutral the front settles unevenly from left to right. Still with foot on brake, selecting Drive again reverses the settling again. Shockers maybe? There is a knock from the driver's side front when encountering a sudden dip in the road such as a smooth-sided pothole, but no knock on a raised lump in the road. Regards Paul

After my experiences I don't trust the locals to correctly set a bespoke toe, let alone determine it, Tony. Is it a trial-and-error on-the-road thing, or can your amazing equipment find the right setting? Paul

It was the right call, undoubtedly. The risk of shearing was real. Nice though your reception area is, i didn't fancy sleeping there til the Monday! Incidentally, some tramlining is still evident, though much less than before. Could that be the Primacies? Until this year I've always used the original D8Z's but I can't find them any more. Best, Paul

Hi Scorps Thanks for the welcome! This is certainly an interesting place, I'm learning lots. I'd certainly be interested in hearing of your suspension/geo issues on the LS400 - it might help my case with the main dealers involved, who frankly should have been more aware of these issues, and should have looked a lot more closely. Best, Paul

I am the "Mr X" in this thread. The Lexus Owners Club Forum suggested I contact WiM. It took 3 long (260 miles) journeys to WiM to resolve this issue - one visit to diagnose, the next to fit the new arms (but WiM couldn't carry out the work because one of the bolts was seized and liable to shear), and a 3rd journey (armed with new bolts!) to complete the job. I can't thank WiM enough. They're professional in every way, extremely helpful, and everything was explained to me in language I can understand. Any more suspension issues and Tony and the crew will be my first point of call. It's worth the long journey. Well done, guys. Thoroughly recommended. It's probably best if I keep my thoughts on the main Lexus dealers to myself. Paul
