Tundra vibration

You can check the propeller shaft straightness from the rear of the transmission to the rear gear case. Adjust at the mid carrier bearing if off. I checked this on my 2 wheel drive '03 Tundra.

I had a similar problem when I bought my used '01 Tacoma TRD 4x4 (39K miles) except that it had BFGoodrich tires on it with maybe 10K miles on them. I had a vibration at around 63 mph and it was pretty bad. I rotated and re-balanced the tires which helped a bit but the vibration was still there. I also tried varying the tire pressure with no luck. The dealer I bought the truck from said the tires looked cupped but I really couldn't tell myself. After a while I just broke down and bought a set of Bridgestone's and that did the trick.

Continental/General tires aren't the best....Try putting the spare on each side of the front and if that makes a difference, you know you have a bad tire. A tire shop with a Hunter GSP9700 Road Force balancer can diagnose tire or wheel problems that an ordinary balancer will pass. http://209.176.154.132/

Also, many of us don't like Toyota's alignment spec for these trucks. Their factory spec is too wide and sometimes gives poor results, including some weird vibrations, kind'a like a supermarket shopping cart with a bad caster. Find a shop with a Hunter alignment rack and their CAMM alignment console. Insist that they balance to these specs--and that they nail these specs: camber: +0.25 degrees caster: +2.00 degrees total toe: +0.08 degrees

Lots of times you'll get better results from a good independent shop rather than a dealership.

I have a 2002 Tundra TRD 2WD. I just replaced the factory tires with Michelin. What a difference. It's smoother, even inflated to a higher pressure. And the traction on the street is much better. It doesn't squeal around corners when I goose it anymore. I do have posi.

In the rain it is also much better. I tried a few times to get it to slide, it's not easy. It used to slide real easily with the original tires.

If this does it just driving at those speeds while braking? Then its rotors. If it does it without braking, just driving, its the tires. Even if they are perfect in balance, its usually coenicity, or sidewall stiffness variation and this gives you those symptoms. Find a shop with a tire balancer that has a way of measuring "road force variation".

I had some vibration with the OEM Tires (BF Goodrich) on my 2002 Tundra 4x4 and finally at 15,000 miles I put 4 of the Top Rated Yokahama's on it... I now have absolutely no vibration and the smoothest ride ever on a pick-up truck... And they go great in the mud and the rain and the snow... Check out The Tire Rack Web Site for a great price...
