Replaced new if I understand the description correctly the ones that point at the gear box? Big round bush on the body end? New Lexus items no change sadly

I have the sportcross and I’d probably describe the rear the same way. It’s like there is lateral as well as vertical movement for me? The rear does not remain still but combined with vertical movement and lateral movement the end result is diagonal 45 degree travel in response to wumps and large bumps (not small rattle bumps) in relation to my other new post I’d also suspect bush play either in rear control arm or subframe bushes but I’m told they are fine structurally and the car has always had the issue so I have assumed it’s normal, in an abnormal that’s how they are sort of way. id presume after market poly or some other less comfortable bush option would be the fix but assumption is the mother of all…. well you know the saying certainly in other cars high speed cornering has led to various instability issues and poly bushings have fixed it at the expense of some small amount of ride comfort all other times. so the world of compromise for the masses is possibly the culprit I guess

Thanks for your reply but the brakes have been done with new pads and discs after this issue started and made no odds as the issue remained the wear on the pads was equal both sides on each set. There is no unusual sensation from the brakes in feel or performance to me that fact that hard braking is fine suggests play and that play is taken up by braking forces as the weight of the car is thrown forward. Im really surprised not to find bush play tbh

Hi slight creak front right while winding the steering from lock to lock, but… the main issue is a wobble…. Or tank slapper in motorcycling terms, from the steering wheel during certain braking conditions. Not hard braking that’s fine . But if you jab the brakes, or Brake gently it’s like the start of the first brake application sets up a wobble in play in the wishbones bushes or control arms or some component that has play in it allowing the road wheel position to flap and this is then felt at the steering wheel as a subtle left right left repeat wobble that gently fades out or you stop braking But I can’t find any play in any bushes. Rear control arms have been replaced by genuine Lexus but no change at all. Top mount looks on to me. I’ve pried every joint and all seems solid. No play in any ball joints. the only thing seems odd is play in the shocks shaft visible under the gator when prying the spring away from the top wishbone….it’s as the shaft enters the shock body but the car was jacked up wheels hanging so there will be very little shaft within the body, and anyway that doesn’t affect the wheel position or the steering, wiggle that all you like the steering does not seem to move when reaching through the driver’s window, there no oil weep the shock shaft is clean. Both sides are the same i could replace the shocks that’s fine bur I’m not convinced that’s the cause of the wobble at the steering wheel under gentle braking…? oh to add, wheels are not buckled brake disks run true to dial gauge tyres are round no bulges or anything un true, bearings are fine
