Hello all,
New LS 460 owner (2010 swb). Owned the car for two months now and started hearing a clunk noise from the rear when the car accelerates very slowly. Showed it to the dealer and they could not replicate.
Also hearing a water rustling noise from the right side (appears to be coming from the passenger door); again, this occurs only when the car is accelerating gently from rest.

Any help/ideas greatly appreciated.
Thank you

 

Hi - my 2010 SWB had all kids of suspension issues. When I had the rear clunk it was the struts. As for the water noise I cannot help but when mine was in for service once they noticed something like that and it was the water pump I think. Hope your able to clear those issues up.

 

Do you hear it all the time? If so, drive the car with the mechanic next time you take it to the dealer and demonstrate the clunk to them. Could be any number of rear suspension/differential/driveshaft components.

 

In regards to the clunk noise from the rear, make sure the spare tire in the trunk is properly secured.
