why are you doing 100mph on a public road

ozzy

does it only shake above 100? I'd say it's the wheel balance. I doubt any tyre fitter would check the balance at that speed. Take it back to the wheel place and get them to re-check the balance - you shouldn't be charged for this.

do you think about any mecanical problem? coz every time after done tracking and wheel balance they say perfect!!!!

V12_Z

yes,it only shacks above 100,not even 99mph!

Have u tried to get the 4WD alignment done? Mine did the same, but not as fast as 100mph.. did the balancing thing, no change.. got the alignment done.. no shakes/rattles..

You might want to invest in some spelling lessons before driving over a 100mph...

no it is the wheel balancing

take it to a diff place that have better equipment or drive at speeds of less than 100 mph

Gotta say, I preferred 'shack' to 'shake'.

It's wheel balance. The better balanced all FOUR of your wheels are, the faster you can go without noticing problems.

It is more likely a buckled wheel (or two!) if you have had it balanced so many times - they couldn't get it wrong THAT many times. Hope this helps.
