| I have a 2005 Buick Lesabre with less than 10,000 miles. The car has a consistent vibration at highway speeds even though we have tried a new set of tires and a complete rotation and balancing of the tires. The dealer indicates there is no problem with the car; however, the vibration persist. Is anyone else having this problem? | |

Replying to: wjohns02 (Jan 23, 2006 6:27 pm) The tires needed to be Road Force balanced using a Hunter 9700 balancer. If your dealer doesn't have one, find a dealer who does. This adjusts for the uneveness in the tire's rolling height when under pressure. In other words, many tires don't roll round; even if they're balanced they crush differently on one part than another under the car's weight. So they essentially roll as if they are not round. Park Avenue and some LeSAbres and Sevilles went to Michelin tires (Symmetry) to get away from tire imperfection. The company swapped tires on Park AVenues to put on Michelins to fix the problem. Also, the wheel alignment affected my 03 with 16 wheels and Michelin symmetrys that it came with. I had a good service manager who used the vibration analyzer to be sure it was wheel and tire speed related. I told him that after he had really carefully balanced them, it seemed to oscillate on uphill pulls but not ont he downhill pulls o smooth interstate in Tennessee. He felt the alignment wear on tires and took it in. The rear were out of toe and the front also. He set them to what he considered the middle even though they were within tolerance. GM paid for alignment touchup up to 12000 miles. So get back with alignment complaint andget them to print it out. Also do Force Balancing. Fixed it. Ain't perfect, but no car is. They stayed balanced until 35K and I paid to have them rebalance  $7.50 each. What tires were on the car and what ones did you replace with? |

Replying to: shoshm (May 01, 2006 11:18 am) Was the car aligned correctly? Has the car been driven with the vibration analyzer attached to various parts to diagnose the vibration type? Were the wheels force-balanced on Hunter 9700 by someone who knows what they're doing? Preferably a GM dealer who knows what's needed for trouble-shooting the vibrations in the stiffer frames with lighter parts in today's modern cars? |
