Do Not Sell My Personal Information Jump to content

Recommended Posts

I have a 2003 GX470 with around 155k miles. It recently started to get a front end shake which isn't horrible, but you definitely feel it pretty good. I know the rear air suspension has a small leak, but the bags stay inflated for the most part. It feels like it is coming from the front more than the rear. I brought it to the dealership and they said something about the CV boots and something with the steering column I believe. I don't have the sheet they gave me to read exactly what it said. Could either of these be the reason for the front end shake? Has anyone else experienced this and have some insight? I sure as heck do not want to pay the dealership to fix either of these as they charge an arm and a leg.

If the vibration is when the vehicle is driving along then it could be a damaged/worn Constant Velocity Joint or bent driveshaft. Other areas it could be are Wheel Bearing or even a lump in one of the tyres (jack up each corner so the wheel is off just off the ground and spin the wheel slowly while looking between the ground and the tread area to see if there is any deviation within the clearance indicating a deformed tyre or bulge in the tread area. Also check the sidewalls for damage)

If the vibration occurs when braking then the rotors are probably warped....easily checked with a Dial Test Indicator.

Let us know what you find

Should this part of my boot be sealed? Looks like a lot of grease around it. May have a serious leak and it may have been there for a while causing more issues to my axle. This may be part of my problem

There certainly shouldn't be any grease or oil around there but looking at the quantity it doesn't look serious enough to cause a vibration through the vehicle.

Even so, it would be worth keeping on top of and cleaning off to see exactly where it is coming from.

Josh; I had the same issue with vibration at 65 mph with my 2005 with 130K miles. I thought I needed new front shock absorbers - the tire guy at the dealership recommended road force balancing for all wheels.

I had them road force balanced, and all vibration issues went away.

No amount of conventional balancing cured it; $160 and well worth it.

The GXs usually have a bad vibration issue due to high road force in the wheels. Especially after you've gotten a wheel rotation and then start noticing the virbration. But Yes, by simply balancing the wheels and correcting the road force, it will take the vibration away. Start with the cheaper fix before you get into repairing the cv boots or performing any type of suspension work.

Regarding the leaked grease from the CV boot, I discovered the same issue about  7+ years ago. There was no clamp there so I got a CV boot clamp and a tool to install one. SInce then I haven't noticed any problem. In addition to this boot issue, my RX suffered the same  years ago and that eventually lead to failure(making sound when turning the wheel)  so I got it replaced. So I wouldn't be surprise if that could be the culprit.  Another thing, if your tires are worn pretty low, you may feel the shake more so than a newer tire. Its been my experience that after I replaced my tires(about 4 sets since I owned my GX), the shake goes away or not as apparent.

I test drove two 2006 Lexus GX470s, a 2013 GX460, a 2004 Lexus GX470, all with 135k to 225k miles and they all had some sort of shimmy/shake to their steering wheels. 
I then drove 2.5 hours North to private sale 2004 GX470 with 172k miles, and it drove fantastic with only little-to-no shakes, with only mild steering shake during medium to heavy braking. I was impressed and bought it!

The next day my neighborhood mechanic changed out the front rotors and installed ceramic brake pads, changed the driver’s side (front, yes I know there are only “front”) CV axels, replaced the motor and cabin air filters, checked:  the water pump and timing belt, differential oil, etc. 

I thought it would drive like a dream now—but it’s worse than any of the four other GX’s I test drove. It shakes without even braking at crushing at 50-65 mph, and it now shakes like it’s possessed with even under light braking! WTH?!? “Time to google”...

I am going to find someone in the Twin Cities that does “Hunter (brand) road force tire balancing” and then, I’ll probably get an alignment, too. I’m grateful for this Lexus owner’s club and the members here—I’ll post what happens next after the two services.

Often folks wait too long to get a front end alignment so that can lead to something called "cup'd" tires. In other words they are no longer completely round. So they ride like your tires are egg shaped. It's something to do with the steel belts getting out of a proper alignment. Some tires sucumb to it easier than others. 

My boss used to say "you can get an egg to balance but you can't make it ride good." Old school tire shops used to shave the high spots off.

My former mentor told me his wife had a new set of tires go to shaking and the shop reveresed them and it solved the problem. Say you have a black wall with logos on the inside on the driver side front. They revered that tire on that wheel so the inside was now the outside. 

Now why your car rolled good one day and not good the next? That's strange. Did he rotate your tires while doing the work? Perhaps a wheel weight fell off without knowing it? 

Good luck and we look forward to hearing back from you.

I google searched  “Hunter (brand) road force wheel balance machine” and found the contact info for the “Hunter” brand, and emailed the local rep, who emailed me back on a Saturday morning with a partial list of shops in the Twin Cities who operated their “load bearing” wheel balancing machines. I was already 5+ calls into local tire shops and found two that verified they had this specific machine, 4 wheel balancing ranged from $59 to $89 plus tax. Some shops never even heard of the technology, or machine. 
I kept calling because I wanted to find a shop within 10-30 minutes from my home, and open on a Saturday. 
Discount Tire in Apple Valley MN’s Manager Dustin is a Stud! He verified they had the machine and “knew how to use it, too!” I guess this is an issue . Dustin also asked my what my issue was in detail and then offered that I might need specialized Lug Nuts because the Lexus Stud was 12mm and the holes in my wheels were 14mm, and this could also be the reason why my wheels “suddenly” became even worse after new CV Joint, Front Brake Rotors and Ceramic Pads—the front two wheels may not be centered properly on the wheel studs. He’d “personally” check out my vehicle once the tires were off of it. 
He then let me know that the new brake rotors/pads looked good, but I should upgrade the Lug Nuts with a specialized set that would “self-center” each wheel because of a sleeve/collar that would take up the 12-14mm gap. I said sure, as the total cost of Hunter Road Force Balancing and these new Lug Nuts was only $85 plus tax, and I wanted my “New-me” Lexus to ride smoothly again. 
When I picked my 2004 GX470 from Discount Tire, Dustin went into the shop to grabbed a standard lug nut and the Sleeved/Collared lug nuts he had installed—visually they totally made sense to me and I was excited to test drive my Lexus. Dustin also mentioned that my new front brakes seemed to be “on” the rotors all the time, and they were “grabby” compared to the rear brakes, possibly heating up the pads/rotors and told me to see if a brake shop could adjust them. I called the local Lexus dealership and they said they were not adjustable calipers.

After paying, I eagerly drove my Lexus and tested the brakes and my vehicle at different speeds—no steering shake or shimmy! It felt even better than it did the day I test drove it prior to purchasing it! I am so relieved!
I don’t know which service solved my shake/shimmy steering wheel and ride quality problems, but I am glad I did both as they were under $100 total. I am still going to have my Lexus get a four wheel alignment and it is at the alignment shop now. 
I am thankful for the forum members that post here and hope my experience helps others too!

Here is a photo of a similar Lug Nut with the extended “sleeve/collar“, it is NOT the exact ones on my wheels but a good visual representation, and a photo of my broken CV Axle, and my Lexus.

      Hello everyone, I’m new GX owner, and unfortunately I kind of regret it...
      Long story short, I bought the vehicle from a used dealer, and it had a bad O-ring seal between the actuator and the T case. But, I did not discover this until about 400 miles later, I noticed grinding coming from the center console. I drained the T case and all that come out was a small about of oil and metal shavings. After filling it, it still made the grinding/ratcheting noise. The dealer owned up and fixed the leak, but told me not to worry about the noise. 
      Fast forward about 3 months and the Lexus dealer wants $4600 to service the T case, and no local mechanics will work on it because it requires “specialty tools.”
      At this point I feel stupid going back this late to the dealer and asking them to repair the issue they caused. However, there are after market kits available or used T cases ($200 and $2000 respectively). 
      If you were in my shoes, what would you do? The truck is drivable, but I bought it because I wanted a bullet proof rig! 
      I appreciate any help!

      I installed a Rutech bypass and block off plates and my initial check engine light went out.  A day later I get the P0418 error telling me relay A is bad or there is faulty wiring etc.  
      Does anyone know where the SAIS relay is located for P0418?  I have been searching to the point of insanity. :)
      thank you

      This is kind of hard to explain without you feeling it, but basically the car shakes or rumbles when driving or sitting. You could also call it a shudder.
      This happens at pretty much all speeds, but is less noticeable when going faster.
      The RPM's don't change much, if at all when this happens.
      It is very intermittent, but it has become a problem because I will try to floor the car to overcome this and all of the sudden the car will full send.
      It also makes the car stall, again being very dangerous.
      I have ran the car out of fuel about a dozen times now because the fuel gauge/full dash lights don't work.
      The car will always start just fine which makes me think it is more serious than a bad fuel pump/clogged filter.
      There are no engine lights on (they should work, they come on when the key is at acc).
      The "Trac" orange light will come on sometimes (not to be confused with the "Trac Off" light that does not work) , but doesn't seem to correlate with the issue.
      Apologies for the bad description, but it is really the best I can come up with.
      Thanks for any help you can offer.

      2007 ES350 with 180K........while accelerating have motor vibration. Also if at speed, any speed,  any increase on the pedal and get vibration. Seems to be getting worse since first noticed a number of months ago. Recent tire rotation and balance, alienment, new struts all around. Mechanic says could be motor mount(s). How to verify which mount, or should all be replaced? Does engine have to be pulled? Any idea the cost? And last, if it is a motor mount, what's worse case if I do nothing?
