The Gnome

The dealer replaced the rear shocks...so unless there is a design flaw with them, it's not the shocks. However, there is a "slip ring" that goes around the body of the shock...and there is a small gap between which MAY cause a rattle...but not likely. The springs were heavily greased (according to the mechanic) and the noise seemed to lessen, however it was still there. I have not had the parking brake cable looked at yet. I may wait until my next service. The level of noise seems to vary by day. I haven't found a pattern that indicates it's is better when hot/cold/etc. (by the way, if it was unclear....both left and right sides make noise) Thanks for the response.

Just purchased/installed a few F-Sport options last month (intake, sway bars, shocks, and springs). Everytime I go over small bumps (i.e. driveways, speed bumps, manholes, etc.), there is a squeak/creak/noise from either the right or left rear suspension. It was installed by a Toyota dealership, however I've also had a Lexus dealership try to diagnose the problem. They had no cause/solution. I've read through some forums, but have not found the exact fix (some have said it's the parking brake cable...others said rubber dampeners are required). If anyone has any ideas they can share, it would be greatly appreciated. Thx. By the way....despite the noise....the suspension upgrade has made driving fun again!!

Not 100% sure this is your issue, but there is a TSIB concerning "a rattle noise coming from the rear of the vehicle when driving over bumps." Supposedly it is caused by the parking brake cable. Here is the TSIB: L-SB-0024-08 If this is it, repairs should be covered under warranty.
