Front end vibration

[Redster]

I took a long drive (900 miles) in the MM this weekend. I noticed a detectable vibration on some of the freeway bumps, mostly at speeds in excess of 70 and fairly big bumps such as expansion joints on bridges. The first thing that occurs to me that is it might be flex in the tires. They are the first Goodrich tires I have ever driven on.
Anyone notice a similar vibration? The steering wheel doesn't shimmy like a 57 Chevy I used to drive that would vibrate in similar situations (probably was those heat lowered springs),

I have posted several times 1 reg balance 2 road force balance. front end alignment (to center steering wheel).TSB on the body mounts (too tight) a little better, but on bumpy road surface shake still very noticeable. Showed my car to a friend the other day ,he looked at the tires and immediatly noticed the red dot stamped on the tire was not aligned (indexed) to the valve stem. After all this I will be happy this solves my vibe .One would think this should have been checked first??:mad:

Are you kidding????? Anyway, I just check the tires and the dot is NOT lined up with the valve stem. But you gotta admit, this sounds kinda weird.

I think you guys are taking this DOT thing a little too far...
The dot is to mark the location of the high balance spot in the tire.
If this is lined with the valve stem of the wheel, in most cases,
you would use the minimum amount of weight to balance the assembly.
That is all this does and it is NOT an exact science.

must have gotten late posted same thing twice

:cool: :shake: :banana: :cry: :nono: :up: [QUOTE=Bradley G]Talked with three different people including my own SM where I work at our co. party last nite he admitted to me this is the first thing they should have tried to solve this issue . I'm going to call tire rack tomorrow to see if they will suggest a shop that will be a little more on the ball . If the tires require more than 2 oz. of balance weights that they warranty them
