After my oil change and tire rotation my steering wheel start shaking going at 50mph?

i just got my oil change and tire rotation at fire stone last time. Now when I hit 50mph my steering wheel start shaking. It usually shake at 90mph. What could be the problem? Is the wheel too loose when they did the rotation? I am planning to go back to fire stone and ask them to inspect it, but I want to know what could be the problem first so they wont give me stupid answer.|||You need your tires balanced or either they didn't tighten up the lug nuts.|||You probably have a warped rotor or drum in the back. This wears tires unevenly, causing them to go out of balance.





When they rotated the tires, they put the back tires up front. If they rotate them back to the back, it should drive like before.





When you bought tires, was lifetime balancing included? If not, you'll have to pay about $10 or so per tire to get them balanced again. |||just to set the record Straight... a wheel alignment will not cause a vibration, the tires that were on the rear may need to be balanced but you should have all four tires balanced and checked for out of round. you can balance a square but it will still cause a vibe.|||One of your tires is out of balance. They may have dropped one of the balancing weights when they performed the tire rotation.|||your rear tires were either out of balance, or have flat spots. and they put them in the front so you can now feel it.|||First, check that all your lug nuts are tightened.





It's probably a tire that's out of balance or maybe a bent rim.





|||You either have a tire out of balance (most likely) or need an alignment. |||One of your wheels (probably front) is bent, or the tire is out of balance or out of round.|||tires out of balance,they mite not tighten up lug nuts right/front end needs alignment|||you may need a front end alignment.
