Lexus RX 2010-15 :: Substantial Clunk Somewhere In The Rear


Jun 25, 2013

I've had my 2012 RX 350 for more than a year now. From the very beginning I had this occasional problem: Stopping fairly quickly (but NOT any sort of panic stop) at a small downhill, I sometimes would get a rather substantial clunk somewhere in the rear. It sounded pretty serious--axle or suspension, I thought. Of course when I first brought it to my dealer. I couldn't duplicate it. But then, I convinced the service manager to send a mechanic to my house, where there's a place where it often happens.

Finally, he heard the clunk . The service manager did some research and concluded I was hearing an "over-extension of the suspension". He sent another RX350 to my house, and indeed, we were able to replicate the clunk at the same place, in that different vehicle. On the other hand, a friend, who also has an RX350 said he never had the problem.

The service manager says there is nothing abnormal about the clunk. This is hard for me to believe. It's a really substantial clunk and in my 45 years of driving I've never experienced anything like it.

Lexus LS 2007+ :: Clunk At Rear And Dash Popping

Now that the cold weather is here, I am finding more and more issues. Besides a clunk in the rear that I have to have looked at, I have the dreaded dash popping. I have read to use felt and jam it between the window.

Also it seems like the headliner is popping too? Haven't heard of that. I plan on bringing it to the dealer after the holidays for the rear clunk, but will they fix any of this under platinum warranty?

Lexus RX 2004-09 :: Rear End Clunk On Passenger Side

I have had an issue with a clunk in the rear end. Passenger side. It was only happening when I would hit a bump. Over the last couple days it has started getting worse. At about 40 mph and above the clunking will increase and can be fairly rapid. Also have a slight vibration at that speed. Do not feel it in the steering wheel.

I think I have narrowed it down to the rear knuckle? bushing. While holding onto the bushing I rocked the top of the tire in and out to produce the clunk. I could feel it in that spot. I had ordered a set of bushings, months ago, which claimed to be a direct replacement.

Tonight I decided to try and swap them out. Should be easy. Nope. The old bushing will not come out. I have some pictures. Maybe I need to call my mechanic in the morning? My diagnosis might be wrong anyway?

Lexus RX 2004-09 :: Clunk Noise From Rear During Slow Speed

Problem is noise that you can describe as clunk, not any harsh or sharp sound. It appears on road bumps or unevenness during slow speed up to about 40kph/25mph. The noise has not been heard over that speed even in bad bumpy roads.

List of thing I've done so far:
- Driven with empty rear compartments
- Driven with open rear door
- Checked the tightness of spare tyre
- Replaced rear stabilizer bar linkages
- Replaced rear stabilizer bar bushings
- Replaced rear axle carrier knuckle bushings

Could it be possible not coming from rear? Should I sit in the cargo space while somebody else driving, any success with this? What to do next?

Lexus ES 2007-12 :: AFS Light Flashing / Clunk In Right Rear On Turns

AFS Flashing and there is a clunk in the right rear on turns and it bottoms out over speed bumps . According to service manual and internet search, this combo may be a problem with the rear height control sensor sub assembly or rear No. 2 suspension arm or other suspension issue. AFS flashes because the car height changes affecting the headlight adjustment leading to AFS flash.

Dealer says "Yes sensor is mounted to the control arm and if it's broken in half, it would clunk and cause afs light to flash."

Lexus GX 2004-09 :: Clunk In Rear End When Slowly Drive Over Speed Bumps

I recently bought a CPO 2007 GX 470 with 110k miles. At no charge dealer made repairs re the Bulletin about clunk in rear when I slowly drive over speed bumps. Had all front and rear shocks raced with OEM shocks, and four new Michellin MS2 tires installed. Rear end still feels like is is bottoming out sometimes during regular local and freeway driving when going over different times of road bumps.

My 'i89 a Dodge Ramdharger ( only car I ever bought brand new off the lot ) with 174k miles and old shocks and original springs drives better over bumps and speed bumps than the GX. One Lexus dealer said the reason is because the rear air bags ( that are not leaking )do not fill up fast enough when going move bumps and that can cause the bottoming out feeling. My mechanic is going to check it over again. What could be causing the bottoming out feeling?

Lexus GS 2013+ :: Muffled Clunk Or Thunk Sound From Passenger Rear When Driving Over Bumps

So I know the 2013 GS (or many GS in general) have had complaints of squeaks and rattles. My GS has a couple but are very minor and only occasional.

I do have one noise that seems unusual though. When I am driving and drive over moderate bumps in the road, I hear a muffled clunk or thunk type of noise only from the rear passenger area and never anywhere else.

My car is a stock CPO 2013 F sport and not lowered or anything. Stock rims and tires. The shock does not seem to be leaking.

The noise happens regardless of if I am in regular or sport+ modes. Was going to mention it to the dealer at my next oil change and door trim replacement appointment I need to make Ina couple months.

Just picked up a new 2014 rx fsport and 75% of the time I release the e-brake it has a loud clunk as if metal smashing metal. I tried releasing it really slow and it still does the same. The vehicle is parked on flat pavement. It is not a low click noise that I am used to but a loud clunk.

Golf IV / Jetta IV :: 2002 1.8t - Substantial Coolant Leak

I noticed today when I was in a drive thru that ,y Jetta was smoking a little.... Went home ate my food and came out and looked underneath the Jetta and found a substantial coolant leak..... My heater core is bad I know this already... Would this cause coolant to leak outside the car or the carpet only??? I jacked up the car and checked for leaks... There is coolant all over the rear engine mount... And the driver side corner of the engine is pretty soaked in coolant....I can't pin point the leak..... There is a connection coming out of the side of the head that's got a little pinky crusty stuff on it but I can't see anywhere around it...

Passat (B5) :: Substantial Amount Of Grease On Driver Side Rim

So I was cleaning my wheels the other day and noticed a substantial amount of grease on my drive side rim. Today as I climbed under the car to do an oil change, I took a better look at the other side of the wheel/brake assembly, they are all covered in grease. The rubber boot just behind my driver side disc has torn open and is throwing grease all over the place.

A) how hard is the repair to DIY
B) is it called the outter CV boot?
C) what should it cost me for parts?

When are the Germans going to provide something that doesn't require weekly maintence???!??? Just rattled!!!

Ford - Thunderbird :: 1963 - Intermittent Idle When Warm Up After Substantial Drive

Engine is a 69 390, fresh rebuild by the PO... Aluminum intake manifold and new Edelbrock 4bbl Drop in Crane ignition.

Runs great... Except when its warm out, or even on cold days when its warmed up after a substantial drive..

AT that point here is what happens: No issue until I shut it off then it diesels badly, THEN.. When I restart it will not idle, dies.. If I keep my foot on the accelerator it will keep running, but not well.. If I let it run for a good while, 5-10 mins, it smooths out... Consistently acts like this .. Again.. Not when the engine is cold, and not on a cold day until it really warms up..

I suspected a vacuum leak? Replaced any suspicious vac tubing.. Cant get to the AT modulator easily, have not checked it yet?? Also suspect the intake manifold??

Sonata I45 (YF - 2011+) :: 2.4L Engine Failure / Substantial Rattle Emerged From Under The Hood

I was driving our '11 Sonata Limited 2.4 today with wife and infant son... While merging onto a main road, I accelerated to switch lanes without slowing traffic and noticed the car felt oddly underpowered.. I kept my foot on the gas, and a substantial rattle emerged from under the hood so I let off and drove steady on... We made it to our destination and I popped the hood to find oil soaked into the valve cover and head... I checked the oil and the stick was still wet, but since the car was just running I'm not sure the exact level...

Unfortunately, I recognize the noise it made on the road, and I'm 99% certain it spun a rod bearing... In other words, the engine is shot. 63,362 miles, synthetic oil changes every 4k-5k miles, dealer maintained...

Lexus RX 2010-15 :: Rear Speaker Volume Very Low?

The rear speaker volume in my 2010 RX 350 is very low. They produce sound but can only be heard when I put the balance almost completely in the rear. I prefer not to pay hundreds to the dealer and then possibly be told that I need to go to an audio specialist.

Ford Super Duty (1999-2016) :: Substantial Vibration When Torque Converter Locks

I have a bone stock (other than exhaust) F-250 SD, 6.0 auto, 185k miles. I have a substantial vibration when the torque converter locks - about 50-55 mph. Once the transmission warms up (i.e. 4-5 miles from a cold start) the vibration goes away and the transmission performs flawlessly. Backing out of the throttle and allowing the TC to unlock makes the vibration go away, as does shifting into neutral. There is no noise, just a vibration that will shake the whole truck. Transmission fluid looks good, and showing full. Have had the truck about 4 months, and have not flushed or replaced the filters on transmission.

I've seen a couple of similar threads on vibrations, but not one where the vibration will completely go away. I'm thinking replace the torque converter but wanted to get more information from the experienced experts that know these 5R110s better.

2007 F-250 King Ranch 6.0 PSD, 5R110W, 4" Turbo Back, Otherwise bone stock, 185k.

Lexus RX 2010-15 :: Metallic Vacuum Sound Seems To Come From Right Rear Of Car

I have an issue with my 2011 350 that is quite perplexing. I get an intermittent sound... best I can describe it is like a metallic vacuum sound that seems to come from the right rear of the car. There is no pattern to when it arises... comes and goes. I've been to the dealership with it 3 times and of course it did not occur. They must think I am hallucinating. I thought it might be an exhaust problem.
