Lexus LS 2007+ :: Suspension Rattling Clunking Sound On LS460
Jun 15, 2016
Why my suspension is so loud and clunky are doing a swaybar link and upper control arm replacement? I did remove the air suspension unit in order to access and remove the bolts that hold the upper control arm bracket mount onto the frame.
I did not think that would do any harm. Now my suspension is way louder than it ever was to begin with.. I just did a visual inspection and saw that my original parts were cracked and worn in the bushings and links. So I did a swap.

So just yesterday, I'm driving and I noticed that dreadful thunking suspension noise. Is this the control arm problem I've been hearing about so much? The 2007 only has 40,000 miles on it. I guess the age of the car is the culprit there right? Or maybe these arms really do go out quickly.

My 2009 LS460 AWD with air suspension now, at 56,000 miles, has this noise frequently during driving and sometimes at idle.
Like an air compressor for a few seconds. It's not loud, but you definitely hear the whine/air type noise. It's almost not even bothersome for me as I've gotten used to it. But when my wife or others are in the car they always ask "what is that"

Where the air suspension release valves are on an 07 LS460? I recently had suspension sensor issues which has resulted in the car being jacked up like a monster truck, and now even with the sensor replaced it will not come back down.
It's almost like the car has detected the fault and disabled the compressor. I have tried pulling the battery to see if that would reset everything but it hasn't worked. I'm hoping that if I can release the valve the car will realize that it everything is back at normal height?

My LS460 recently developed a rattle from the front drivers side. It's triggered more by rumbles/vibrations from an uneven surface rather than speed bumps or large pot holes.
It sounds a bit like a washer vibrating on a metal tray (for what that's worth)!
Interestingly though it gets a LOT worse when the car is in 'Comfort' suspension mode, and is nowhere near as bad in 'Sports' mode. So it seems that having the suspension higher gives this thing more room to rattle.
I noticed in the service history that the front passenger air strut was replaced 30k ago, so I'm worrying that there is a large bill on the horizon.

New LS 460 owner (2010 swb). Owned the car for two months now and started hearing a clunk noise from the rear when the car accelerates very slowly. Showed it to the dealer and they could not replicate.
Also hearing a water rustling noise from the right side (appears to be coming from the passenger door); again, this occurs only when the car is accelerating gently from rest.

I have a 2009 460 awd with adjustable suspension and when making a right turn the front left side makes a noise. I have had the dealer look at it 5 times or more but each time I am told that there are no problems. Now that the weather is getting colder it is becoming more pronounced.

So a few months ago I started hearing some clunking under the vehicle so I got under there and sure enough the control arm bushings were shot. Took it in to Lexus for service and had them look while at it to confirm that is indeed the issue. After replacing all 8 of the front end control arms and 2 of the ball joints the clunking is still there. Seems to only do it while turning. Regardless whether giving it gas or braking.
What it might be? Its fairly loud and definitely coming from the front suspension (I can feel it through the steering). The control arms are brand new. The ball joints are brand new. Just checked the tie rods and they're are in good shape. What else should I check for?

Not sure if this is normal with the air suspension but over poor city roads at low speed, there is a light rattling noise from the suspension. I think it is the front. Sounds like worn bushings but the car has only done 30,000 miles.
If this is the sort of early symptoms that would be expected with wear in the control arms?

Purchased a new LS 460 first of this year. Definitely not as quite as my LS430 and has an annoying pinging sound which the dealership says can't be fixed and is a normal sound for the car. Talked today with Service Manager and his lead mechanic and was told this is normal.
Problem: When I purchased this car for wife I had an expectation that it would be a quite running car. Not sound like a diesel engine, especially when at idle. I've read about others with the same problem and wonder if there is a fix out there for this annoyance. Lexus claims it is a fuel injector noise. Some people here stated that had there car fixed by Lexus Engineers.

I have had a clunk in the front end that started out as a light clunk that was sometimes noticeable. It has now turned into a clunk that can be heard very often. It sounds like a hollow clunk. I'll try to explain it so it makes sense...If I'm going over a bump or speed bump or something like that it doesn't really do it noticeably. If I'm driving a get to a place where the road is uneven or there is a hole or pothole and the front end seems to "fall into the hole", then the sound is very audible, and I can feel it slightly in the steering wheel and under my feet in the drivers floorboard. So, I've had the front end checked out 4 times and between what they said to do and what I've read on here...here is what I've done so far......
Changed end links with moog end links
Changed sway bar bushings with moog bushings
Undid the bushing mounts from the front frame and wired the sway bar up to keep from flopping around. No change in sounds
Didn't get rid of the clunk....
Had front end shop check out truck... They said ball joints were ok, no play in them. They did say that they could feel some "clicking in the pitman arm pivot" when turning the wheel. Like something was loose in box.
I've changed shocks and bearings.
I can grab a hold of the passenger outer tie rod at the adjustment sleeve and rotate the tir rod and it will rotate around in the socket and hitting on the insertion point and make a metal thud sound.
Again, took into shop and they said that would be normal b/c the tie rods have to have that to keep from binding up in front end.
My thinking is that if the tie rod rotates that much, then it is rotating the drag link which in turn puts stress on the pitman arm which in turn has either broken or sheared the pinion shaft inside the box and then when I go over a hole, it moves and all of the above is put into motion.
Shop (Ford) basically called me an idiot and that wouldn't be the cause.
So, now onto my thoughts and questions....
Radius arm bushings
Axle bushings (????? how many and where are they all located)
tie rods and drag links..

After going through a 1996 avalon, 2003 sequoia, 2004 tundra, 2004 highlander, 1978 celica, and a 1990 4runner i decided to buy myself a beautiful new 2011 camry LE.
I have had the car now for under 6 months i've put under 10k miles on it.
Already the front left strut has been replaced. Right rear strut has been replaced.
Now the front left strut needs replacing less than 2000 miles later again!
The car is pretty fun to drive but seriously...every time it rains i have to replace my suspension. it starts creaking and clunking and rattling literally every time it rains.
Every time it as rained. my car goes to the dealership and gets outfitted for new strut somewhere! I don't know why my car is giving me these kind of issues. its not very toyota like.

I just purchased my first VW, a 2012 Tiguan SE in Night Blue Metallic. The level of fit and finish, handling, and general feel are miles ahead of my old '04 Jeep Liberty.
Anyway, I've had the car for about 250 miles and have noticed a clunking/rattling noise coming from what sounds like the front passenger side suspension arm. The noise is fairly quiet but seems to consistently happen when turning left over uneven pavement.
I plan on taking it to the dealer this weekend and it is only a minor annoyance, but a shame since the rest of the vehicle is so quiet and refined.

I went to go start my LS460... put the heat on, its fine.. when I turn the heat up on high I get this annoying high pitched sound. It has to do with the heat system because when I turn it off it goes away... I'm scared to keep the car running...

I started hearing a small rattling sound coming at low speeds while driving. It's a tic tic rattle which almost sounds like a cat, but it only does it while driving and not all the times. I had a smiling noise once on one of my cars and it was a torque converter. It's not the brakes, as applying brakes doesn't work. Also the whole front end is brand new. It motor related. Can a heat shield for a cat come loose?
I'm also dealing with a wind noise coming from a driver side window. My car has the updated thicker windows. The noise goes away if I lower the driver side window just a fraction. So having it closed all the way creates more noise. Other than that wind noise is at a minimum.

I was told yesterday the rattling sound coming from the engine maybe my a/c compressor maybe going out, it's late April in Texas and this is the worst possible time. I have 89000 miles on my 08 ES 350.

I have a clunking noise from the right front suspension when going over bumps. I've replaced the Strut bushings that were collapsed, the control arm bushings that had play and the noise is still there. There is no play in the links. There is a slight noise in the sway bar bushings when struck with a rubber mallet. I hate to keep replacing parts chasing down this noise.

Today, I took my 2007 Saab 9-3 2.0T with 67,000 miles on it to a local mechanic to check the right front suspension that has been making a clunking sound when hitting potholes, etc. I was told that the right front coil spring is broken. This afternoon, I looked on line on some of the Saab discussion boards and saw that for cars up 2006 that there was an extended warranty offered for 10 years and 120,000 miles due to multiple cars with this problem caused by an, allegedly, faulty design that allowed the springs to corrode and fail prematurely in snow belt states that salt the roads.

My 2005 Honda Pilot has 125k miles and has developed an occasional clunking sound from the rear suspension. It seems to happen around sharp turns or when the rear suspension is unloaded, like hopping over railroad tracks, or when going over short/sharp bumps. It is inconsistent, in that it does not happen all the time. I was checking and checking for loose parts for months and tugging on suspension parts like arms, links, sway bar, etc. I find nothing loose or clunking or showing signs of loose connections.
Today, I was checking with the car on jack stands and found the "hubs" or sheetmetal covers that the CV boots are clamped to are loose at the differential. I believe this is the sound of the noise. They rotate with the rear wheels and kind of clunk around with some manual pressure applied.
Are they a typical source of trouble? Are they easy to replace? Are they nothing to worry about or is this a precursor to the axles falling out?
