I have GX470 2009, now a little over 80000mileage. The car has been serviced by Dealer all the time. Recently, it has been served brakes, rotors, and new tires, cost a lot of money because no warranty. After the last service, I feel car has vibration around 30mph, not steering, no noise, it is gone when I release gas or just simply accelerate. It is very smooth and steadily at the high speed. Is anyone here having same issue? I called the dealer and was told there might be driveshaft problem. I did find one side rube boot has a little very dark grease leaking (actually not leaking). Just use my finger to remove a little around the end of boot.

Please help me to know the problem before going to dealer, which will cost me a lot of repairing again.

Thanks,

Larry

I would start with checking the balance of the tires.

1. What brand of tire?
2. Did the dealer do the work?
3. Did they do a road-force balance?

Out-of-balance is most noticeable on the front tires - I would move them to the rear (one at a time) to see if the sensation changes.

Balance should be okay.
It only happens around 30mph and gone if I release gas or simply accelerate. In high speed, it prefect smooth. Any way, I will ask Dealer for this.

I bought GX470 to the dealer. The deal technician fixed it and stating it was balance issue, actually re-balanced and switch four tires. Dealer repairing consulter says "driving for while if the variation still exists. Then replacement for new tires (since the tires under warranty).

My car: Lexus GX470
Mileage: 80000
Tire: Brightstone

Thanks,

 

Glad you were able to get it resolved.
