Bad vibration at 65+ after alignment. Caster Problem?

[RyanS13]

So I got alll adjustable arms, because one of my tension rods where bent, and took the car in to get aligned today.

After I got it aligned I took it on the freeway and it had a real bad vibration anywhere above 65mph.

I looked at my alignment sheet and theh caster is at 4.5, and 4.6 when oem specs are 6.0-7.5.

Could this be the cause of the bad vibrations?

i was told i also need a wheel balance beside the aliment

[Chrischeezer]

why were your tension rods bent?

caster shouldnt make a vibration. could be wheel balance. bent wheels, shifted tire belt.

:cool: balance your wheels....

It is not your Caster... and like others said check your wheels, make sure they are not bent. Check the tires, make sure there are no broken or damaged belts. If yo see nothing wrong then have them balanced. Good luck.

It didnt do this before i changed out the arms and stuff though. So how could it be the wheels out of balence? The only thing that changed was the alignment, and the casters is the only thing thats offf, and it waaaaay off.

wheel weights fall of all the time bro. But does your car pull to one side as you drive? From my understanding caster should not cause vibration but a difference in Caster from one side to the other may cause a vehicle to pull to one side. Just throwing that out there. Once again good luck figuring this out.

seriously its not your caster being out, check your tire balance, sounds like too much road force, aka crappy tires....

yes ur tires seem to be out of balance. had a friends car who's would shake then he did a tire balance n all fix.
