Noticing a knock or clunk when rocking your steering wheel left and right while stationary?
This is a known complaint among BMW F20/F21 owners, including M135i and M140i drivers, and can be associated with wear in the steering rack’s internal thrust piece.
This aftermarket steering rack repair kit is designed to address that specific source of noise on compatible racks. Where the thrust piece is responsible and the rest of the rack remains serviceable, it offers a targeted repair without the expense of replacing the complete steering rack.
The symptom can be particularly noticeable when making small back-and-forth steering movements while parked. Some owners also experience knocking or rattling over uneven road surfaces. Replacing the affected thrust piece components and correctly adjusting the assembly can help resolve noise caused by wear in this area.
