I have a loud knock and squeak coming from the right front

This answer was rated:

Hi, i have a loud knock and squeak coming from the right front suspension when going over small bumps ie cats eyes , drains . My car is a 2013 f31 320d msport , i am a Audi master tech and have tested the front suspension but the only thing i can find is there is slight play in the stearing arm on this side. Is there bmw fix for this issue


I'd say its most likely to be a worn strut top bearing

To feel if there's a worn strut top bearing then lightly hold the spring by hand and have your assistant move the steering from left to right with the wheel on the ground - a worn bearing will feel 'notchy' through the spring. The wheel needs to be on the ground for the test to load up the bearing
