Bluey Posted January 22, 2014 Share Posted January 22, 2014 Hi All My 07 250SL is giving a clunk noise from the left rear suspension every time I go over a pothole, rough ground etc. Has anyone else experienced this? I took it my Lexus service team and was told it is only minor and not a hazard, or dangerous to the integrity of the car, and If I really want it gone they would charge about $2000!!! I haven't taken it anywhere else for a check as yet, but wondering if anyone else has experienced this and what was the outcome. TIA Quote Link to comment Share on other sites More sharing options...
LEX055 Posted January 22, 2014 Share Posted January 22, 2014 Are you just running stock suspension?I have seen a few threads around regarding the same issue but normally its after they have upgraded to f-sport suspension.. Quote Link to comment Share on other sites More sharing options...
LEX055 Posted January 22, 2014 Share Posted January 22, 2014 Also were Lexus able to explain what was causing the clunk..? Quote Link to comment Share on other sites More sharing options...
Bluey Posted January 22, 2014 Author Share Posted January 22, 2014 Hi Lex Yes, standard suspension, and all they told me is that it was at the top end so it's hard to get to. I think it is a bush or similar, but can't be sure. Thinking of going to pedders or similar and getting suspension people to give me a better idea.

fearfulmaster Posted January 23, 2014 Share Posted January 23, 2014 Sometimes it is the bushing and sometimes it is as simple as a loose bolt. On another car, the right rear was clunking over speed humps, then over a few months, it progressively got worst until I get a knocking noise all the time. So I got another person to push the car while I identified the source. Turned out just a loose bolt on the strut mount. Tightened the bot and noise gone. You should go to a suspension shop like pedders and get a second opinion. Or if the knock is reproducible when someone push the car, you can try and identify any loose parts yourself.

Trev48 Posted January 31, 2014 Share Posted January 31, 2014 I am having exactly the same problem with my new (latest model) IS250. Any suggestions will be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
Lexus Nerd Posted January 31, 2014 Share Posted January 31, 2014 I am having exactly the same problem with my new (latest model) IS250. Any suggestions will be greatly appreciated. If it's under warranty, have it checked by your Lexus dealer. As with all rattles, squeaks and clunks, they will address the problem until you're certain the problem's gone. (Having said that, it helps if you drive the car to the dealer yourself and don't leave until you know they've reproduced the noise.)

Trev48 Posted January 31, 2014 Share Posted January 31, 2014 Thank you for your advice. Yes, it is still under warranty. I will take it to the dealer early next week and road test it with them to demonstrate the problem. I will post what the outcome is. Quote Link to comment Share on other sites More sharing options...
Trev48 Posted February 5, 2014 Share Posted February 5, 2014 I was advised that the rear end clunk was coming from the park brake shoes. An adjustment of the shoes appears to have resolved the problem. Quote Link to comment Share on other sites More sharing options...
Bluey Posted February 5, 2014 Author Share Posted February 5, 2014 That's interesting Trev. Just wondering when you noticed the clunk? I am getting it over potholes and manhole covers that sit below the road level. Was yours the same? Quote Link to comment Share on other sites More sharing options...
Trev48 Posted February 5, 2014 Share Posted February 5, 2014 Problem first noticed 2/3 months ago when the radio was turned off and windows opened. As such, when I then started specifically listening for it, I could hear it with the radio on and windows closed so I suspect the car may have had the problem from day one. As well as it occurring in instances similar to you, I could also hear it when either of the rear wheels went over the small reflective lane markers (for want of a better description) in multi-lane roads. Lexus dealership advised this was their first awareness of this problem in the current IS250 model and they were going to report it to Lexus Australia.

Bluey Posted February 6, 2014 Author Share Posted February 6, 2014 Thanks Trev. I'll do some investigating of my own. Mine feels like a heavier clunk than I would expect from a park brake shoe, but is definitely an easier fix than pulling out the suspension if I don't need to.

Trev48 Posted June 4, 2014 Share Posted June 4, 2014 The rear end clunk with exactly the same symptoms in my new IS250 has begun to re-occur after what now appears was a temporary fix in February (refer posts late Jan & early Feb). I have the car booked in for it's 15K service next week when I will be requesting it to be fixed again. I will be disappointed if I don't get a PERMANENT fix for the problem this time. It will be the third time I have advised the Dealer of the problem, the 1st being late December, the 2nd late January. Quote Link to comment Share on other sites More sharing options...

Bluey Posted June 4, 2014 Author Share Posted June 4, 2014 Hi Trev I took mine to pedders and they have told me my rear shocks are buggered, after a series of checks/tests, and need replacing. Apparently everything else is ok. Maybe get the service team to check them Quote Link to comment Share on other sites More sharing options...

Trev48 Posted June 13, 2014 Share Posted June 13, 2014 Dealership Service technicians confirmed the clunk was again caused by movement in the handbrake shoes. Action taken to fix under warranty was to remove & clean the handbrake shoes, apply white grease, re-assemble, carry out adjustments then road test. Problem appears to be resolved. Hopefully permanently this time. Quote Link to comment Share on other sites More sharing options...
