your tires may need to be balanced or you might need a front end tie rod. Take it to a brake and muffler shop and they will tell you exactly what the problem is. It's up 2 u if u want them to work on your vehicle. I had the same problem on my car and they wanted $500, I took it 2 my machanic and only paid $150 (including Parts)

1 of 2 things or both, alignment or balance.
Tire out of balance or bent wheel.
I have seen this with bad or unbalanced tires.
It could be wheel balance or worn out steering joints. Have it checked by a trusted garage soon!
Could be that the steering wheel rubber bushing is worn or lose. This bushing is located in the engine compartment, between the end of the steering wheel coulomb and the steering wheel likage...Tom

Wheels are likely out of balance
