Lexus LS 2007+ :: Vibration While Cruising Between 75 - 78 Mph
Dec 9, 2010
I have been noticing some vibration from the rear of the car while cruising between 75-78 mph. I had the tires balanced at Lexus 2 weeks ago and the car feels better but not perfect. I called the service advisor and he said the read out on the balance sheet showed that the tires were balanced perfectly but they will look at it again.
My issue is that I am going to have a set of 22's installed on Monday and I want to make sure nothing is wrong with the car itself because once the aftermarket wheels go on the dealership basically washes their hands of the vibration issues. The tires on the stock wheels are brand new and maybe have 1000 miles on them.

Our FWD Santa Fe Limited had a very noticeable vibration that started around 60mph. Oddly, the vibration will sometimes come and go while cruising at a constant speed on the highway. We went about 30k miles before we had time to get it into the shop.
I asked them to rotate and balance the tires and the vibration was noticeably reduced...initially. Now it's back!
The car has ~65k miles. All 4 Kumho tires match and I believe are original from the factory. I have kept all tires inflated properly.
Our car has the optional 18" wheels. Is it common for these to bend? What else could be the cause here?

Picked up an R about a month ago. Have noticed a harmonic vibration when cruising just above 70 mph to 75 mph from the rear. I can assure you that it is not the wheel balance. Seems to go away if I depress the clutch. I'm thinking it is the butterfly valve on the muffler not fully closing and creating a resonance by fluttering at the rpms (exhaust flow) between 70-75 mph. I haven't tried disconnecting/plugging the vacuum line yet.

I have started noticing a hum or vibration that I can feel in the pedals when I am cruising around 50-60mph. Doesn't matter what gear (automatic trans) I am in, I can feel the gas pedal vibrating slightly at those speeds. Below or above that, it goes away. Any thoughts? I know dealer, dealer, dealer, but wanted to know what you all thought so I can have some direction to lead the mechanic in so they dont tie my car up the whole day.
Don't think it's:
Wheel bearing because I don't hear it all the time.
brakes because I don't feel any vibration at other speeds.
Gear box because I can shift into different gears at different speeds with no sound.
Tires because I just got them rotated and the tread still looks new after 22,000 miles.

Been having a very light vibration when cruising at speed as well as on some lower speed shifts and finally crawled under the truck today to check for drivetrain play. Other than the amazingly soft and sloppy transmission mount I noticed a TON of play in the driveshaft transmission yolk. Didn't feel like the u-joint but actually the tailshaft yolk. Dealer said on the phone they have seen this on a few of the newer trucks and it *should* be covered under the power train warranty. I have the subercab with the 1 piece aluminum driveshaft.

Noticed my 2002 F150 had a very slight vibration in the seat / steering wheel when cruising down the highway at 60 MPH.. Very slight, but was not there 2 weeks ago.. It seem to get a little worst as the 2 weeks progressed. Got all 4 tires balanced and rotated... no luck...Took both rear wheels off-- no problems with tires -- checked bearing clearance-- pushed and twisted on driveshaft yolk to check pinion bearing... nothing found......... last resort was drop back end of driveshaft and check U-joint.. It was tight and dry. Put drive shaft in 12 ton press and pushed out the u-joint bearings. Very dry and joint pins were starting to spall....... I mention this because I had checked " clearance" and "slop" and had "no noise" before removal... Truck has 139K miles on original u-joints .......... Something to keep in mind. Eventually it would have worn to the point that it was obvious, but in the first stages of failure, you just get small symptoms.

I am considering the purchase of a 2008 LS. After conducting research I've noticed that there is a common issue around an odd vibration problem at certain rpm and around control arm bushing's with these cars. I've also noticed that there is a common issue around air suspension issues. I based my conclusion around threads that seem to pop up constantly.

I have a 2002 SD 4WD auto trans extended cab/short bed (92K miles). Run 55psi front and 70 psi rear per door placard. Recently started getting a vibration when cruising at 45MPH and to a lesser extent at 55MPH. I was due for new tires so I got Hercules which where balanced and also had the alignment checked (no problems.) Vibration has subsided greatly but still does it at 45MPH. A little faster or slower and it goes away. I checked the u-joints on the (one-piece) driveshaft and they seem tight. I do not feel any vibration in the steering wheel but really cannot tell if it is coming from the front or the rear.

Steering vibration coming right around 75 to 80 MPH? I have balanced my wheels 3 times to rule out that being the issue. Also the tires are in great shape. At speeds below or above it rolls smooth.

So, I started my journey in getting vibrations out of my car at the dealer (I know, I know, but it's CPO) - had rotors resurfaced, brake job, fluid flushed etc. That worked with pedal pulsing etc.
Now, fast forward 6 months - still have a notable shake at times 40-45, 70-80mph indicated. Took it back to dealer; tires are shot - I figured just a rotate, balance and align would be the cure. I bit the bullet, put on some MXVs and got the car aligned - again, at the dealer. Old tires had the edges fully worn (outside).
Today, after a 200 mile drive, the vibrations are back, and I REALLY don't want to go back to my dealer a third time to resolve this - in addition to not wanting to destroy a brand new set of tires. Who can I turn to to get this under control?

I took it in to Charles barker Lexus (our dealer here) and they said the water pump was leaking, the front struts were totally blown out, and the 2 belt tensioners had some free play.
Got the dealership I purchased from to pay for the water pump but they would not cover the struts because they said the car pass inspection so they don't believe they are damaged.
Got and independent shop to replace the front struts with kyb 551122 for $400 parts and labor. While they were under the car they said the upper and lower control arms looked newer as if they were replaced recently
Got all wheels balanced at a little small used tire shop small change. The vibration that started at 60mph now starts at 65. Question is are all tire balancers created equally?

I ran over something a few weeks ago and one of my rears had a bad vibration. Took it Friday to the wheel shop and found out it was a bad tire, not the rim so I inquired about the Delinte 305/25/22. They said they can have it the same day there but was in a hurry. Paid a deposit and picked up today. Just as CJITTY posted in another thread, the 305s have more vertical wall compared to the 295s so it doesn't look stretched. My fenders are rolled so I'm sure rubbing will not be an issue. Drove home on 4 on the data system and there was no rubbing whatsoever. I, running a different brand 255 in front now but will be switching to the Delinte 265 shortly. It' looks like it'll be a better side wall comparison to the 305s.

My car is a 2008 LS460 SWB. I bought it with 69,000 miles on it, has about 75,000 miles now. Car has had a rear end vibration at speeds of 60 mph+ since I bought it. The vibration seems to lessen when I have a full tank of gas. So...I took it to my Lexus dealer. They put it on the lift and showed me how the two rear tires appeared to be slightly out of round and said that was probably the culprit.
I then bought winter tires and put them on. Still had a vibration. Was told to wait until I put all season tires on, then they'd start to pursue.
I put Pirelli P7s on yesterday. Seem like a great tire, but I'm still feeling a rear end vibration. All 4 wheels were road force balanced. I will be taking my car back to my Lexus dealer to see if they can diagnose. What are causes of rear end vibration. Wheels are not bent, BTW.

I just purchase a new 2012 Lexus LS460 L AWD. Between 35 to 40 MPH I feel a slight vibration in the front end of the car. Once I get above 40 MPH the vibration or wobble goes away. Could it be a tire out of balance? Car was bought new, and currently has 1200 miles on the clock.

I have a weird vibration only at freeway speeds. It's a vibration that lasts 3 seconds but are consistently 2-3 seconds apart. It's a very suttle vibration and can be felt at my feet and slightly on the wheel. My passengers can feel it if I mention it. The key thing about the vibration it's starts and goes away the starts and goes away?

Our 2007 LS 460 (98k miles) drives like a dream except from about 75-85 mph we have a general vibration. Its most evident in the steering wheel but everything in the car has a general vibration. It may have been there for a few months now, but I felt it when I drove it yesterday. There is absolutely no vibration below 75 and none above 85 (I was cruising at 90 mph and the car was solid). I tried to do some investigating:
Tires: Appear to be fine in regards to wear and the tire pressure is about the same in all of them in the mid 30 s. Alignment is fine and the car does not pull to any side.
Brakes: New brake pads about 10k miles ago at dealership and work absolutely fine.
Transmission / engine (I hope not): The car is 7th gear at that speed but it usually is anytime above 50 mph so its quite odd. We don't lose power and no lights are set off.
Body work / damage: doesn't appear to be anything on the front or sides of the car that cause this.

I have a 2008 es350 with 106k miles and I've been trying to fix vibration issue for a few months now. The car vibrates while in park with and without the AC power on, but its worse with the AC on. The vibration was felt in the sterring wheel and wasnt that bad just enough to be annoying. So I researched and did a few thing such as spark plugs change, mass air flow cleaning, new air filter, a few bottles of fuel injection cleaner but nothing improved the vibrations. In fact I think it got worse. So after looking online I ran across a post about vibrations and motor mounts. This is the post I found. [URL] ....
"Most likely, one of the engine mounts are 'torqued'. You can try and neutralize the mounts. Loosen the through bolts of all mounts several (4-5) turns. Then start the car, and drive back and forth several feet (using quick taps on the gas and not just idling) over and over, and let it rest at idle a few seconds before turning off the engine. Now tighten all mounts being careful not to rock the motor, and don't pry or push anything to reach the bolts! (This is where swivels co*me in handy)"
I went ahead and did it on my es and wife's 2010 rx350. It took about 30-40 minutes but I took several breaks. Here are a few pic these are from the RX but the process is almost the same ones.
Top of engine bay on the passanger side this mount is easy youll need a 14 mm wrench. I noticed the bolts here where very tight when i loosened them but when re tightened the bolts it when in very easily.
This the drivers side you'll need a 19 mm wrench. Just turn the wheel all the way to the right to get access.
This one is right behind the radiator in the front middle of the engine. Its a17 mm
This is on the passenger side behind the wheel. It just like the one on the drivers side. Its a 19mm
This one I believe is only on the rx but I didn't look on the es. I could not get to the through bolt so i just loosen the two 17mm bolts.
Once all of the bolts were lose I turned on the car and moved/drove it 2-4 feet in drive several time in the drive way. Then I stepped on the brake pedal hard while in drive and gave some gas nothing crazy maybe up to 3k rpm and for second or 2. I did the same in reverse. After that I put it in drive and felt for vibrations if I still felt something i would repeat until the vibrations stopped. Once they stopped I didn't put the car in park, I turn off the car while in drive and engaged the emergency brake. At this point i re-torqued all the bolts without move anything. Now both the RX and ES and very smooth while stopped while in drive. This a free fix and it worked great.

About month ago I found used lexues es 350, 2008 in one of the dealership and bought it for my daughter . I test drive the car and found the vibration steering on speed 57_65 or .not like real lexues which is smooth. Any way I thought with alignment would be fix. But no luck.
I found another Lexues repair. They said I need to change [B]transmission and motor mount I bought it and after replace same as before.
Some other one told me could be Torque converter. This is really big problem and I can't let her drive the car.

I recently purchased a CPO 2009 LS460. There was a vibration in my seat at 70 mph that I asked them to fix (tire balance). They have done it 3 times now, including road force balance, and the vibration is still there at 70 mph. I assume that it must not be the tires since they have done it 3 times. What else could it be? Should I take it to a tire store (is Lexus as good as tire stores at fixing problems like this)?

I'm having a vibration feeling while driving. The dealership has replaced both lower control arms, bushings, and the right side drive shaft. They have told me that it is caused by my rims and tires. So I purchased new rims and tires and that has not fixed it.

I recently purchased a 2009 es in good condition, the tires were quite old and loud and the car pulled to one side. I purchased some primacy's and they are great, however the pulling/poor alignment was still there, I then took it back to the dealership and they rotated the tires which actually worked with the pulling but then there was a slight vibration from about 100-130, by 140 it's gone, but i seldom drive that fast.... I then had the tires re-balanced and the alignment done again, the vibration perhaps lessened but i can still feel it...
