Ok, I have a 98 LS400 with approximately 76K miles on it that I bought this year. Everything about this car is great. The only problem that I have is with a clunk from the front end, most noticeably coming from the passenger side. I usually hear it when going slow (<30mph), and when I'm going over rough asphalt, prominent speed bumps, or the transition from the street to my driveway (has a rolled over curb). It appears that these road conditions that cause rapid compressions of the suspension system are the conisistent precursor to the "clunk." Other than that, the front end is very tight and smooth. I just had the front struts replaced by a trustworthy mechanic who specializes in Japanese vehicles. This took care of some of the problem, but not all. When I took it in again, he showed me that the front bushings on the front trailing arms were dry and cracking (not the upper or lower control arm). He told me that everything else checks out ok without tearing it apart. He checked the ball joints, sway bar bushings and control arms for looseness and didn't find any. He also made sure every nut and bolt on the front end was tight. My questions are, is it possible to replace the bushings on the trailing arms with changing out the whole part, and does anyone have any other idea as to what could be causing my annoying clunk? Thanks for the help.
