Lexus GS 2006-11 :: 2010 GS350 AWD - Rear Inner Tire Cupping And Make Roar Noise
Oct 11, 2015
I have 2010 GS350 AWD. Tires are Dunlop and have 7000 miles on them and the car has 47k miles. The issue is the rear inner tire are cupping and make roar noise. Car is all stock. I have done alignment twice at the dealer. They are telling me everything is normal. I have personally inspected everything under the car and did not find anything abnormal, no blowing bushing, and no oil coming from struts. I have read there is no camber adjustment in the rear.
What could cause the gs350 AWD this cupping? Only in the rear? Would camber correct such problem?

I've had some noise while doing slow turns for the past 9 months or so, seemingly coming from the rear of the car. It's sort of a rrrrr ----rrrrrr -rrrrr noise, but it has a slight buzz to it too, like something is vibrating. It's hard to say which side it is coming from. It only occurs when turning to the right. But recently it sometimes occurs when going straight, but slow, like when approaching a stop light. Braking seems to have no effect. The other symptom is the left rear tire has very definite cupping. There are easy to see flat spots on the surface of the tire. The tire isn't perfectly round in other words, but more like an alternating sequence of flat spots. The other 3 tires don't have this cupping, they show a normal wear pattern.
I jacked up the rear of the car and tested each tire to see if I could detect anything wrong. I pulled, pushed, twisted. I could detect no play at all in either tire. I spun the tires by hand, and there was no unusual noise. They both just spun quietly, freely, with no apparent wobble or anything unusual. The service manual says the rear wheel bearing is bad if there is 0.2 mm of axial play. I doubt I could have detected 0.2 mm of play the way I did it, just pulling on the tire.
The only other thing I noticed is that the (rear) toe-in adjustment is different on the left than on the left. By this I mean the eccentric bolt-gadget is set on different marks on each side. The right one looks like it is set to have more toe in that the left. The right one is 4 marks positive toe-in, the left is 1 marks positive toe-in. I'm assuming these marks are just for reference, and don't represent the actual toe-in, just that's the setting it took to get the rear wheel alignment correct when the car was built.
Do I have a rear wheel bearing problem? A rear-tire alignment problem? Something else?

I recently notice the front right tire on my GS makes a bearing sound like at 40mph and increases at 55mph. Anything after 60mph is not too bad. I looked at the tire and notice the inner top of the tire is wavy. My brother says the strut is bad. I think not because, the car dose not bounce and strut is dry of fluids. The car has 38K miles on it, alignment was done by dealer at 35K ...
I did rotate the tires front to rear sound went away for a day and started back up again.so I know its not the bearing. Do I need better tires? another alignment? or strut?

The tire roar (not engine or wind noise) is unbelievably loud on my car. I drive a lot between San Diego and OC usually at 80+ and it is difficult to have a conversation on the phone and it is starting to drive me a little crazy. I have the all seasons on my car. I noticed a big difference on my S4 and my 550i when I changed tires to PS 2's from the stock Conti's.

Ok , so now my sun shade is broken and set at 80% open. It will not move at all. 07 GS350. It was fun while it lasted.
Oh wait and my rear-view mirror has a bunch of black inside the mirror.
I will probably have a bunch of stuff for sale soon. BC-R coils with Swift springs , AC front lip, Rear ISF difuser, Lexus Japan Visors and some mods.

I bought my GS new and it has 40K miles now. It is a 2010 GS AWD. Yesterday I get off work, a hot day, I get in the car, started the car, and passenger front window rolled down by it self. I tried to rolled it back up and it would not go up. I shut the car off and re-started and was able to roll it up.
I thought maybe it was the heat. The next day it happened again, but this time while I was driving. There are no funny noises coming from in side the door and no water has ever gotten in there. I also never leave the windows cracked instead I raise the sun roof up for heat to escape. I find this very odd self-operating window. The rest of the windows work just fine.
Battery has never been disconnected. what may be causing this window to operate on its own? a lose wire maybe?

I just spent about $600 on front Lexus Oem struts, Front Strut mounts and labor to try to cure a knocking sound that developed recently. My 2007 GS350 has 84K miles on it. Figured it was time and I had a 50% off labor coupon from Pepboys so it wasn't bad.
Unfortunately that did not cure the problem so I figure it was the upper control arm, but the whole front end was solid. I decided to take one of the Moog sway bar end links off that I just put in and drive around. The noise was completely gone!! So it appears that I had a defective sway bar end link!!!
So before you guys start swapping out front end parts for a suspension noise which is what I've seen when I searched the forum, start with the cheapest one, the end links. Take out the side that makes the noise and drive around to see if the noise goes away. BTW it is safe to drive with one missing. I was able to drive normally with it off.

I had my car drop for a while now on megan ez coilover. Before I bought my new set of wheels, I drove the car with the OEM wheels and they never had any cupping issues. Then after I bought my AME Shallen with 20mm hub centric H&R spacers on Nankang NS, and then they started cupping on the front inside tires after 5000 miles. I had the alignment done and only had the toe adjusted.(don't have camber kit) At first i thought it was the spacers causing the issue, but then I bought Orden's with new Nankang NS and had the toe adjusted to spec's again. Camber is at -3 BTW. Recently i started hearing the same road noise so I inspected the tires and found it was cupping in the front again! I also checked the front end of any damage or worn out bushing and couldn't find any signs of damage. I always keep my tires at 40psi, torque them down evenly, and I'm using hub centric rings. My questions is do you think is the Nankang tires or do I have a suspension problem?

Lately I changed my front brake rotor and the new brake pad. However, When I doing back forward with applying light brake. I can hear "gara gara" noise from the front brake. Sounds like two steel material hiting each other.
Also, there is a different noise comes out when I releasing the brake after local stop. (red light stop or stop sign). I ask the mechanic when I doing the oil change. He checked and said my brake just are fine.
Probably it needs time for the pad break down with the new rotor. I used the Posi ceramic brake pads with the come with shim.

Our 2010 Prius has about 57K miles on it (mostly highway and rural commuting). The rear brakes just started to make some noise the other day at low speeds. It sounds like a light metallic squeal, similar to a brake pad wear indicator. It only occurs at low speeds and in reverse. Last time I checked the pads, they had lots of life, but that was in the spring.
I'd like to take apart the brakes to service them, but I don't know if this is a DIYer job on a Pruis. I have tons of experience on auto repairs, and have done hundreds of brake jobs (I also perform auto restoration as a hobby and have done almost every type of mechanical work on a car). So I am not really worried about my skill, but I am worried about knowing the proper procedure to do the repairs on a Pruis.

I changed my front rotor and brake pad with the oem parts last week. However, it has noise come out everytime when I touch the brake. Is it normal? Or does it need times for break down? Or I did something wrong in installing that cost the noise?

I just had my front brake pads replaced by a local shop. I am now hearing a clunking noise every time I step on the brakes. I got the brake pads from the local Lexus Dealership but had them installed by a local shop. Is it normal to have this clunking for the first couple hundred miles until the brakes "wear" in or do I need to have someone else look at the brakes?

I brought my 2011 GS350 in today for the dealer to fix the rattling noise coming from the dashboard after 2.5 hrs of waiting the car was fixed and I drove it to work and the rattling was minimal but tonight after work it was really cold I drove the car home and the rattling noise seem like it coming from the dashboard area near the windshield and the noise was more noticeable than this morning right after i left the dealer.
I just bought the car on March 3, 2015 so far loving the ride but the rattling noise makes me worry. The car is still under factory warranty until March 29th 2015 I am hoping they can correct the problem before the warranty expires.What should I do next?

I have a 2007 GS350 that seems to "clatter" when I start the engine after it's been sitting for awhile. The clatter only lasts a couple of seconds but it's annoying....sounds like metal on metal. It does not happen when engine is cold or should I say first thing in the morning. It happens after the car has been driven, sat for a few hours and then the clatter occurs when I start the engine. This started a couple of weeks ago....I have 29,000 miles on it.
Took it to the dealer last week, the service rep told us that this is somewhat common and is due to the high pressure direct injection system on this particular engine. He also said this started when they switched from the GS300 to GS350. I'm wondering why it never happened before. The service rep said there's nothing they can do about relatively new Lexus with relatively low miles.
I've always used premium gasoline, got all my oil changes and maintenance done at the Lexus dealership thus far.

I have a 07 gs350. My car wouldn't start this morning let alone turn on. I heard this constant beeping noise coming from the hood and it was the battery. I unplugged the battery and the noise stopped. But once I plugged it back in the noise came back. I was in a rush to get to work this morning so I just unplugged it and let it sit for a few minutes before plugging it back in to see if it work.. it did not. This battery is only about 1 year old too.

My tires are cupping on my Azera. I've had the tires rotated every 7500 miles as required by the maintenance schedule. The tires make a lot of noise while driving, especially at highway speeds.

I recently noticed that when I release the parking brake on our new 15 F-Sport it make a loud noise. It's hard to explain, but it kind of sounds like a spring being released with a clunking sound. (Sorry for the weird description).
When I press the brake to set it I am not pushing it all the way to the floor or forcing it at all. I am just using normal pressure to apply it.

I have 3 new tires and 1 with wave or cupping wear. It is a new tire not even a year used. I went in to get my alignment fixed because I was told the cupping is due to car being out of alignment. They told me I have to replace the tire with the cupping wear on it before they do the alignment. Is this true? or can i keep the tire and not have to shell out more money for a tire that is not even a year old. that being said, I am now doing more research and realizing that cupping is actually due to problems with the shocks. not alignment.
It's a 2009 toyota matrix xrs....
