Lexus LS 2007+ :: Suspension Noisy At Low Speed?
Dec 14, 2013
At my 30,000 mile service about 6 weeks ago I reported to the service manager that the suspension seemed noisy at low speed over undulating side roads. They could not duplicate the noise. Now with the cold weather, the noise has increased considerably to the extent that my wife who claims never to hear any of the noises I obsess about, asked me what is that knocking noise
I have made an appointment at my dealership first thing on Monday and they are going to ride with me and if necessary use the "chassis ears".
From everything I have read it has to be control arm bushings or the air suspension. I think the fact it has worsened considerably now the temperature has dropped eliminates the brake pad rattle possibility.

I got off the highway today and was at a very long light, but enough time to feel my car making slight jerking movements and i saw the car raise a little over an inch.

I just had the rear air compressor suspension replaced, but when it activates it sounds pretty noisy. It doesn't sound normal. What the heck is going on?

Some replaced the rear shock absorbers with Bilstein B$ OEM shocks. One claimed it fixed the problem.
VW dealers and mechanic claim that is normal for the car , no repair necessary?!!?

I have a 2007 Sonata Ltd (63000 miles) and had a clunk in the front suspension. I had the front upper control arms replaced (which were visually badly worn) and that fixed the problem. But now, a several months later another similar clunking noise has developed when I go over those small speed bumps in parking lots.

Have a 2008 B6 3.6 sedan. This car for 2008 comes equipped with a sport suspension and 18" wheels. This car is real noisy on the road especially if the road surface is anything but very smooth. The tires are noisy but the sport suspension seems rough on unsmooth roads. I would like to know if different shocks would make a difference. I want the taught control of course but with better compliance over rough areas.

I have a bothersome bottoming out type of noise coming from near my empty trunk or underneath the trunk area. I have the 17" stock rims with stock mich. tires. I had VW check for the rubber rear shock absorber plate which I do have. I Have the rear tire secured as well as the battery. I have insulated the hard foam tool storage kit so it will not bounce going over irregular surfaces. Yet I still get this sound like a loose bar hitting against the underneath on less than perfect roads.

In cold weather, front suspension is very noisy. I've replaced stabilizer bar bushings, stabilizer bar links, control arms (complete with new bushings and ball joints). A few months prior, I replaced struts with Monroe quick struts. Noise appears when I hit a pot hole or go over a speed bump. Not really a creaking, almost like a slapping sound. I've taken a look at motor mounts and they look OK. Now that the weather is warm there's no noise. Rack and pinion were replaced about a year ago so engine cradle was removed. I removed it and reinstalled. Also installed new tie rod ends and lubed the inner tie rod joints.

What the defective part could be? GS300 has run 90.000km, sound can be recognized by passing for example gullys or small bumps with speed of ~20km/h. Increasing speed let the sound disappear. I have already replaced stabilizer bar bushes, link assy and lower ball joint assy.

I have elantra 2012 with approx mileage of 47,000 kms. I started to fell that the front suspension becoming noisy while driving slowely on the bumps and rough roads. This noise feels even on steering wheel that this has some connection to steering rod in somewhere.
I had took the car to local dealership here in Riyadh, Saudi Arabia where the kept the car for about a weak and return it say that the car is fixed, but the noise was there or came back in days only.
Second time, the same thing happened, approached the dealership they took and hand over the car, removing some air from all 4 tires a (which i have noticed). but the problem remains the same.
I have noticed as well that the car is not so stable on the roads while driving at different speeds.

1998 4X4. My rear suspension is so loud and noisy it's driving me crazy. I've soaked the thing many times with wd40 but it doesnt seem to work or work not more than a day or two.
I've tried to make a pic with my phone because I think at the rear side of the leafs they are separating way too much... I've got no more than about 150lbs and a LPG-tank on my bed...
Moreover I think my truck rides bad. I know it's no Cadillac and I'm running 33s and its a 4x4 BUT I've got quite new Rancho shocks and the whole front suspension is in good shape and it got an alignment a month ago...
So what do you think, after 181.000mls time to get new rear leafs or take the old ones apart, free them from the rust, paint & grease them and put them back together?

I'm looking at an 2009 LS460L with the touring package. I have read that the air suspension has reliability issues. Is this a common problem or just a few isolated cases?

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?

For several months there has been a rumble from the rear like suspension is faulty but inspection of strut and other parts showed no obvious issues. 60,000 miles one owner.

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?

I have a 1994 celica GT, 2.2 with a 5 speed. I thought I either had bad tire noise, or maybe a wheel bearing noise, I put the car up on jack stands, started the car and put it in gear, and the noise I have is a loud growling sound, which gets worse the faster the wheel spins. I took a 2x4 and stopped the passenger side tire (drive wheel) so the driver's side would spin, the noise went away. From what I can tell, or am guessing, the noise is coming from the trans. Could this be a bearing in the trans case? Of course I can't find an exploded view of the trans!

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.

The rear suspension on my 2013 F Sport AWD with 27,000 miles has started to squeak slightly. It doesn't do it all the time but is audible from within the car even with the stereo at low volume. When the road is smooth it's quiet but it'll squeak on even slightly uneven pavement.
Of course the F Sport has air suspension. I haven't experimented with the different ride settings or height adjustment yet but it is audible in Normal mode.

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.

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?
