MUCH more likely for an X5 is as Marcel stated (I lived this as well). Tension strut bushings, ball joints and control arm ball joints (ALL in the front suspension). If you have more than 100 to 150 000 km on the car and this has NEVER been done, expect to do these & do all three.'

Yes, don't throw money the wrong place but also take care of your car as you should; it's not a Lada.
