Question about 1998 Lexus Gs 400

2 Answers

How can I diagnose a clunking noise in the front end of my car? It's a 13-year-old Lexus GS400. Sometimes there's a light clunk associated with braking. Other times there's a similar clunk when rolling at low speed but not braking. It could be two different noises from two different sources, but they are similar. The car feels and sounds solid going over bumps and small potholes, and the steering feels secure. The control arms were replaced with new bushings about a year ago. I'm hoping you can help!

It's most likely the CV joints on one or both sides. Check the CV joints.

Definitely have the front end and brakes checked out at a place like Sears where the diagnostic is a no charge deal.

They may be able to detect what parts are obviously loose while it's on a lift.

I would not let this go very long.

The price might be high to fix this on a Lexus compared to a Chevy, but I think that it's worth investigating.

Where did you have the control arm bushings replaced?

Power windows won't work. they are not rolling up or down.


It can only be one of a few things. First if it is the switch it won't make any sound at all when you press the button. If you can hear a sound, then the motor is running. If it has a 'clunk-clunk-clunk' sound to it then the gear plugs in the window motor need replacing which always happens around 10 years old. If you hear the motor running without the 'clunk-clunk-clunk' then the regulator cable has jumped track and the regulator will need replacing.
