Hi, just that u be aware that after I changed the upper arms, not only did the screeching noise from the front wheels disappear, when I turned the steering wheel while parking ie car was stationary , but the vibrating noise that used to come from the left side of my front door had also disappeared. The door’s vibrating noise was audible when driving over uneven surface but now it is gone. My mechanic showed me the comparisons of current installed genuine Lexus upper arms vs previous set installed. They differ slightly. Apparently, the old set was not genuine Lexus part. So appears only genuine Lexus parts will work properly for these functions.

Attached below is the genuine Lexus part model.

 

Nice info to know. Thanks.
