update:
just got a chance to drop it off today...when driving today it happened at 55-60 mph. ill know by tonight whats wrong with it. scariest drive ever . praying its just wheel balancing and not spacers messed up

What did the spacer look when you took the wheel off? You'd have noticed immediately if it was messed up.

i didnt get a chance to do that

it snowed more so i really couldnt do it its at the dealer now my buddy is looking at it

Summer tires, this past few days have been cold u need winter tires

Improper parking brake adjustment could cause the whole car to shake. If it was adjusted too tight the rear parking brake shoes will always make contact and once get overheated it will cause nasty shimmy/vibration like symptoms.

update: the wheel just wasnt balance he fixed it and drove it on the highway and everything was fine thank god :)

thanks to everyone for the help though if this happens again i will deffinitly keep what all of u said in mind

Glad the forum helped over FB ;)

Glad it's finally over....

It was worth the weight.... :icon17:
