drewbryant1 Posted February 25, 2009 Share Posted February 25, 2009 I have a 98' LS 400 that vibrates at 80 mph. I thought it was the tires, so I had them replaced, but my LS still vibrates at 80. It does not vibrate below or above 80?? Anyone know what to look for? Quote Link to comment Share on other sites More sharing options...
amcdonal86 Posted February 25, 2009 Share Posted February 25, 2009 For me, it turned out to be the strut rod bushings. Quote Link to comment Share on other sites More sharing options...

Let me find you my thread that explains in details the problem that I had and then parts that I replaced to fix them. Quote Link to comment Share on other sites More sharing options...
amcdonal86 Posted February 25, 2009 Share Posted February 25, 2009 http://us.lexusownersclub.com/forums/index...showtopic=54323 There is the thread. I was actually trying to fix a creaking noise I heard when I drove over large dips in the road, but through the process, I replaced the strut rods/bushings. It immediately cured a vibration problem that I had at highway speeds that was not cured by an alignment or a wheel balance. I hope that helps.

Thank you for the details! I don't think I am skilled enough or equipped to do it myself, but It is huge to actually know what the problem is. Again, thank you.

amcdonal86 Posted February 25, 2009 Share Posted February 25, 2009 How many miles are on the car? Quote Link to comment Share on other sites More sharing options...
ClueLessLex Posted March 4, 2009 Share Posted March 4, 2009 How many miles are on the car? Athough much less likely, are you confident of your wheel balance? Typically you see the problem come up at 62, 72, 82, etc., but once in a while, a weight comes off, and the problem seems to be worse at one particular speed. It would be cheaper to check this first, but as I said, it's much less likely IMHO than a problem with the struts or geometry. Just covering all the bases. ;) Quote Link to comment Share on other sites More sharing options...

Although it's likely that his strut rod bushings are bad, it would be silly not to balance the wheels first. Quote Link to comment Share on other sites More sharing options...
