ok i rotated my tires today and after hitting 70mph my steering wheel started going crazy earthquake on me. vibration like a mother. anyone had the same prob? how to fix it? helppp.

 

alligment...

 

unbalanced somewhere?

 

do you have directional tires?

that could be a factor

do you have uneven tread?

that could too

did you criss cross htem ?

 

If a tire is out of balance or too worn, and you bring it from the rear to the front, it will cause exactly what you are describing.

go to your local tire shop and get your wheels balanced that should correct your problem.

 

as mentioned, balance the tires.
While on lift, check wheel bearing.

 

aha thats exsectly wha i did. so should i put them back the way they were? or just balance it?

 

Could be:

- Uneven Tread on the rear tires since u Rotated them...

- Needs to be Rebalanced & Adjust air pressure...

Maybe Alignment....

 

Alignment is the least possible cause (and if it is, there is wear somewhere else in the front end).

If they are directional tires, just put them on the same sides of the car they were so they face the right direction, but still leave the front to back alone (so you have still rotated them). Drive the car, if the vibration continues (90% chance it will) then take it to have them balanced.

 

Common rotating procedure (modern anyway) is to pull the rear tires to the front on the same side of the car. If you cross the tires by mistake, they will be rotating in the opposite direection. This situation could cause all sorts of bad results....including vibration, alignment trouble, and all the way up to tire FAILURE (not common, but it does happen!)

Worn or irregular tires (due to improper wear or under/over inflation) can cause this too....as can improperly balanced tires.

I would check (in order):

1) Tire pressure

2) Tires rotating in the proper direction

3) Dropped wheel weights/tires out of balance

4) Irregular/excessive tire wear

5) Front end alignment (unlikely)

Any or ALL of these could contribute to your woes.....but like we're all taught early on:

K.I.S.S!

Go from easy to complex....the answer lies somwhere inbetween!
