Had my 3rd alignment done today at local dealership, also had them do a Force Balance on the wheels to try and fix the vibration at 60-70mph.
Below are the numbers for the wheel balance:
Front Left: 21 w/6oz.
Front right: 43 w/43oz.
Rear Left: 52 w/17.25oz.
Rear Right: 35 w/21.25oz.
Those were the numbers and amount of weight added to balance. They stated the front left is good, but the other three were high. They said that normally, you would unseat the tire, rotate 180 and try another balance. But they were unable to do this since they don't have the right equipment to do this without damaging the rims. They said give it a go and see if it helped. Vibs have lessened somewhat, but can still feel slightly at 60, but not as bad. Will let it ride for awhile and see what develops. Looked at the rims, there are ALOT of weights on the backside of those rims (3 rows per). Hard to believe they couldn't break it down and rotate, but at least they didn't try and damage the rims in the process.
As for the alignment, lets hope this one holds up this round.
