Lexus RX 2004-09 :: RX330 Air Suspension - Rattling Noise Over Large And Small Bumps At High And Low Speeds
Aug 25, 2014
I have an 04 rx 330 with air suspension. The swaybar end links have just been replaced on the front and a rattling noise persists.
The noise happens over large and small bumps at high and low speeds at normal and low vehicle height. When the height is at "HI" the noise is louder and it feels as though the front end is shaking loose over bumps at 10 km/h+.
I took it in and was advised to replace the end links, they did so and returned it claiming the noise was gone. The air compressor and struts are in working condition.
I have done a search through the forum, not extensive... I was wondering which other components come loose/wear and cause a clunk/rattle/shudder noise.
Also, tires are new and at approx. 32-34 psi.

I'm getting ready to do some maintenance such as flushing the brake fluid, new air filter, and changing spark plugs. I've noticed lately a noise from what I'm assuming is my front suspension that can be heard when going over small bumps on roads at low speeds. It sound like a squeaky spring, almost like something needs to be oiled. I'm still on stock suspension with close to 80k on the clock, so I was wondering if there is anything in particular I should look for when I'm messing around the wheels bleeding brakes, or if there is a common procedure to lubricate something so the noise stops. I can hear it from inside the cabin so I imagine you can hear it from outside the car.

I have a rattling noise coming from the front suspension (both sides) when going over small bumps. Most people point to ball joints, but I find my case odd because I just replaced
Upper/Lower ball joints
Track bar
Tie rod ends
Shocks
Front U joints
Drag link
I did not touch the leaf springs or the sway bar, except to grease the links, which otherwise looked good.

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.

I have a Gs 430 - 2006. After hitting bumps in the highway big or small it seems like my dash or suspension squeaks inside the car. Since I can hear it so clearly I'm leaning towards its the dash or something behind the dash, It seems to be coming from the drivers side.What could it be?

Car has 170k kilometers , just over 100k miles on it; GL model so no sport suspension. Noise occurs going over small bumps.
Stabilizer links are the only front ends parts that were changed so far(12 months ago). Can't feel any play in tierods or ball joints, even the struts don't show signs of leakage and bounce test seems to show they are still okay.
Noise appears to come from front of car ; but I hate guessing and throwing money away. Fished a few large chunks of gravel trapped in subframe cross member around steering rack; no change.

I seem to be having a front end noise that only started up a few weeks ago.. The suspension doesn't make any noise over small bumps, only for larger ones. It makes the most noise when pulling into a drive way or something with a steeper grade from a flat street.
The noise I am experiencing sounds more like a scraping. It's not the power steering pump and it's not the brakes. Also, nothing is under the car that would cause this type of noise. It doesn't click or sound like a CV joint, I know what that sounds like. It also has no affect on any other performance of the car. I have tried jumping/pushing down on the car and it cannot seemed to be re-produced. Where I can start looking?

When going over large bumps and dips I'm hearing a very high pitched squeaking noise coming from the rear end. Over small bumps I hear nothing, it's only the large bumps where I hear the squeak.

My truck is making a metal on metal rattling noise when going over undulations or the type of vibration when you drive over a rumble strip.
It seems to be coming from underneath the engine area, but not quite sure. The sound is like a kettle lid clanking on the actual kettle when the water's boiling if you can hear what I mean. No noise when just driving.

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.

It has 85K miles and rides very choppy/harsh. I feel even a very small dip/hump/bump when driving and it's coming from rear of the car.
What needs to be replaced and/or checked other than the rear shocks? Everything is stock and correct tire pressure.

My 2005 RX330 has run fine for all 45000 miles to date. One exception is that there is a high pitched hum that becomes noticeable once the car reaches 30 mph and continues to increase pitch until about 45mph. The hum seems to disappear when going faster than 45. If you cruise on a quiet street at 30mph the hum will stay steady if you maintain speed. The hum will increase if you accelerate.
But... if you take your foot off the gas pedal the hum instantly stops. Put your foot back on the pedal and it instantly starts. You can almost "play a song" by taking your foot off and on the pedal. Lexus service clearly heard the sound during a test drive, but could not figure it out.

I recently lowered my 2015 rc350 f sport awd with tanabe springs. I am hearing the "hinge" noise when i go over small bumps, in all modes.
I think i am hearing it from the left front or rear side. Is this from lowering the car or something wrong with it?

Thought it was another AC flap that is playing up but it was the small plastic flap next to the tyre that was giving me the headache.
Still, could not find the rattle at the rear which i think is caused by the underfloor storage compartments. Thats for another day.

Its been awhile since I've posted, but this is annoying me! Everytime I drive over a small imperfection on the road, I hear this "rattle" or "small thunk" that sounds like either plastic panels in the rear, or maybe the rear suspension.
I ensured the rear seats were locked in place, I even removed that flimsy rear deck, and even drove with my seats down, and I still hear the sound.
I park on some bumpy terrain at my house, and sometimes I'll go over speed bumps maybe a little too fast, but not really fast.
Its just a sound that's never been there before, and I can't hear it unless I have the music off. Its not overly loud, but that "rattle" or "thunk" just makes me this car feel not so "new and refined" anymore.

So I've got some creaking going on at low speeds only over small bumps. Sounds like it's coming from the passenger rear area. It's an 08 with just under 28k miles. I'm not noticing any issue indicating the strut being blown, it's just an annoying creaking. I didn't realize how noticeable it was outside the car until driving through a parking garage with the windows down on Friday.

I recently lowered my 2012 Beetle with HR super sport springs/stock struts.. So this annoying tin rattling sound has come out. I just replaced the strut mounts thinking they separated like they are known to do. Sound Still there. Now my thinking either it is the sway bar end links being too long or possibly I have aftermarket wheels and aluminum hub rings it could be rattling over small bumps? Could it be the strut bearings? I've been over everything that I can think of and nothing is loose.

I have a 2012 Tig SEL with 18" wheels with factory 235-50-18 tires and stock suspension. The car rides pretty smooth for the most part, but I also find that it's sensitive to lots of small bumps and the suspension is not as smooth as friends other small SUV's. What do you all think about how the Tig rides overall?

I've noticed, maybe a handful of times in the 5k miles I've owned the car, that the engine will rattle excessively for maybe 30 seconds or so on a drive. This only happens during high load/low speeds and I think after the engine has been off for at least about 10-15 minutes. It doesn't happen on start up, only after the car is warm, but hasn't been using the engine for a bit. I'm thinking this is fuel enrichment (really rough running) because the cat has cooled.

Noticed a squeak noise from the rear suspension when going over big bumps or humps, even going in or out tall driveways?

I have a 2004 F150 4x4 5.4. Over the last few weeks I've noticed that when the truck has been parked for even a short time, when I start to move out I am getting a thumping noise from the rear, almost sounds and feels as though I am driving over small speed bumps, but once i get going it seems fine. Where to start?
