Bump, Bump, Bump???

Zuke · March 8

I think this noise, that comes from the back end, has been there since I have owned the car. For some reason it has now started to bug me .

I only hear it at very low (5mph ish or less) under slight braking. Couldn't say if it was at a full wheel turn.

Any ideas ?

If it happens when you go over ridges, speed bumps etc then have a look at the boot lid. Mine was/is badly adjusted and the boot lid was lightly banging against the body/bumper area. I have temporarily fixed it with a bit of draught excluder. Worth a look anyway? There is no adjustment on the bump stops and I cannot find any longer ones so maybe Lexus can adjust it at the next service for a princely sum?

Hiya Gray, no it's definitely only when the brakes are slightly applied. It used to be a single bump but lately it has doubled to bump bump.

Might be warped discs.

Might be dead bodies. I know I watched the wrong film before bed last night.

If you know a friendly garage owner I think it would be a good idea to get it on the ramp and do the usual checks on brake and suspension components. We are lucky we have a good local chap who will do something like this for free. Just a quick telephone call to check if the ramp is free and 10 mins for a look see.
