agc Posted June 17, 2005 Share Posted June 17, 2005 All I have a question regarding my suspension. I have had my car for about 5 months now and it is great but have noticed a cluking noise during braking, but only during slow speed (about 5-15 mph). There is no noise when I am driving anything above that. I also hear a clukinh noise (not load at all, but still there) when I go over certain bumps (large or sharp), especially when city driving. I did search this site extensively and it looks like it could be my lower control arm. Can you guys give me your opinion. Also if it is where can I get the part and about how much does it cost.

nc211 Posted June 17, 2005 Share Posted June 17, 2005 could be lower control arm and/or strut rod. If you've got the clunk over bumps, then I would think it's the control arm. I had my strut rods replaced, and still had that clunk on bumps. replaced all my control arms, and it was gone. After inspecting the old parts, the lower was in a lot worse shape than the uppers. What year is your car and I'll find the parts for ya'. Quote Link to comment Share on other sites More sharing options...

nc211 Posted June 17, 2005 Share Posted June 17, 2005 No sweat amigo. Check out the attachment. #8 is the lower control arm. You can get it for $190. # 12 is the strut rod, for $89. Here is the link where I found them. Select your car, and look in the collision catelog under front suspension components. Dealer prices are about $50-$60+ more. These two aren't too hard to do yourself, but an indie mechanic can do this as well. Find one that doesn't charge by hourly rate for each part, they overlap. I would almost bet that if your lower control arm is worn out, the strut rod is worn out too "taking more load pressure from failing control arm bushing." I would suggest doing them both at the same time since they're tied together. This is not a dealer required repair, and I wouldn't take it to them. You'll pay 4 x what you should if you do. http://www.trademotion.com/partlocator/ind...=20&catalogid=2 Quote Link to comment Share on other sites More sharing options...
blake918 Posted June 17, 2005 Share Posted June 17, 2005 I would guess strut rods. My car used to do the same things-clunk when braking and hitting large bumbs, but drove beautifully otherwise. I had an indep Lexus shop change the 2 strut rods, and all has been well. Quote Link to comment Share on other sites More sharing options...
agc Posted June 17, 2005 Author Share Posted June 17, 2005 Thanks blake918, I just spoke to Sewell Lexus and they also think that it is more likely that the strut bar is bad and not the lower control arm. FYI I have a 2000 LS400 with 37k miles. Quote Link to comment Share on other sites More sharing options...
nc211 Posted June 17, 2005 Share Posted June 17, 2005 with only 37k miles on the car, i agree that it's probably just the strut rod. Quote Link to comment Share on other sites More sharing options...
