Folks, first of all, Merry Christmas and wish you a happy and prosperous new year. I have a 1990 LS400 with 276,000 miles and my suspension is noisy when i take the car out of the parking in reverse. It kind of makes a knocking sound. I replaced the:- 1) front struts (KYB) 2) wheel bearings 3) Lower ball joints This improved the stiffness of the front side and removed the noise 90% but still there is some noise coming. I also got the brakes inspected and the shim kit is good. Any suggestions what to look for next? Thanks, Kallol. Seattle, WA. USA.
