Hi guys, I'm looking for help with this noise i've got coming from the front end when driving slow over uneven pavement or speed bumps, specifically when i drive over a speed bump one wheel at a time (frame twisting). It doesn't do it when i drive perfectly straight onto a speed bump (both wheels same time). I don't feel it in the steering wheel or pedals. The dealer though it was the front sway bar bushing or links. I replaced both and noise still there. Has anyone ever had this issue? I posted a video of it to my Google Drive, link below (ignore the sound at 0:11 - i think i hit the phone with something):

Sounds to me like the exhaust might be tapping the body somewhere?

 

So the dealer “thought” it could be the sway bar bushings and endlinks and you simply replaced them without confirming it was actually that? No one on these forums can diagnose correctly a car over a video without personally inspecting the car in person. If anyone could they would be millionaires. Take your car to a shop that’s trust worthy and have them properly diagnose it because if you want you can continue the guessing game and you’ll end up replacing a bunch of unnecessary parts that aren’t even the cause.

 

so just a followup on the issue which I've finally had resolved. The dealer used ChassisEAR to locate the noise coming from the radiator support bracket/reinforcement bar which had 2 bolts missing and the other 4 loose! Much thanks to the pros at Jim Pattison Lexus North Vancouver for figuring it out.

 

I had no idea anything like the ChassisEAR existed.... lol. What a nice thing to stumble on for myself.

 

I would definitely get it checked out but when this happened to me it was the upper control arm ball joint bushing now I have figs engineering bushing on it now and sound went away for me . But make shure its it before changing things .
