hi guys i own a 2004 bmw x5 4.4 and today i did an oil change and got my steering wheel cover replaced (old one was scratched up) after i left the mechanic my steering wheel when going straight has to tilt to the right...and if i move it back to the straight position the car moves to the left slightly. how do i get the steering wheel back to normal ?

what do you guys think the problem is? do i need an allignment? or CV Boots/Joints?

thanks in advance
