That's great news. Even if it came out of your own pocket, I'd spend the $70 to get rid of the vibration.

Beware that extra labor may be involved if the tires need to be broken off the bead a few times and adjusted on the wheel. The GSP locates the high/heavy and low/light spots on the wheel and tire. It displays this info on the screen advising the operator where to locate the tire on the wheel for optimum balance. There's a lot more science in it than that, but that's all we need to know.

 

Ballistic F150
Basically what this machine does other than balence the tire is locate the high spot on each tire and measures the force that it hits the ground with it. Hence the term "road force" Ford spec is a max of 25lbs. If the tire is out of the spec the machine will measure the rim runout and and determine the best locating of the tire on the rim. If the road force is too far out and rotating the tire on the rim will not bring it in spec you replace the tire. I have seen tires with road force of 48 pounds on a 05 minivan causing a bad vibration. The two tires I replace the other day were brand new from the parts dept. I installed them and there were just as bad as the ones i took off. So another words a tire can have high road force right from the manufacture.

 

Wow, I'm having the same problem only I'm not sure if it's the tires and wheels or the exhaust. My vib is between 16-20 and the dealer says it's my Borla exhaust. They said they disconnected it at the manifold and drove it and it went away!!! My tires and wheels are Michelin and Centerline 20" neither of which were cheap nor the exhaust. Anyone else have the problem with the exhaust?

Well, I had my truck in the shop on Monday 16th to get the road force balance done. When I picked it up the steering wheel shimmy is far worse than it was before and the vibration in the rest of the truck is only slightly better. I called them back and informed the service advisor of this and he said I need to speak to the shop forman. I tried to contact the forman twice and left a message on his answering service with no reply.

Let the runaround begin!

From my conversation with the service advisor I got the impression they are going to blame everything on the aftermarket wheels and tires.

Thatex, I think most tire and wheel problems like I’m having show up from 50-70mph.
