Anyone experience any front end vibration just between 70-75mph?? It seems fin up to 70 mph and over 75mph to 80 mph range??

Any ideas?? It drives straight so it isn't out of alignment.

I have a 1998 SC300 with 34,000 miles on it. Just bought from Lexus dealer and it is Lexus Certified.

Your tires need to be balanced. Wheel Alignment being off causes the car to pull to one side. Vibration usually means time to balance the tires

yep, needs a tire balance. My SC was doing the same thing at around 60mph. I got the tires balanced and the shaking is gone.

Thanks---

I just bought the car a few weeks ago from a Lexus dealer and it is Lexus Certified and the tires looked almost brand new.....I would have thought they would have checked everything out before selling it......guess the Lexus Certification process isn't very tough.

I had the same problem with my 93 SC400. Mine was occuring at around 75 mph. I had the tires rebalanced at least three times and was getting nowhere. The tire shop gave up and advised that I probably had bent wheels or out of round tires. Horse*****! I finally found an aftermarket and wheel ("Wheel Image" in St. Louis, Missouri) store that has a fella who used a little imagination and applied the laws of physics to the problem of balancing the tires. He applied weights to the inner rim of the wheels and then counter balanced/ supplemented those weights with adhesive weights on the flat surface of the inner part of the wheel. The car drives smooth as silk now.

No tire is perfectly round. They all have a high spot and low spot. The high spot and low spot should be matched up with the respective counterparts on the wheel. Then, the tire should be balanced. This should provide optimal results as far as a achieving a vibration free ride.
