This bulletin applies to BMW Series 2, 3 and 4 vehicles. A thumping noise may be heard from the front axle during slow speed turning. 

The noise frequently occurs at outside temperatures above 75 degrees Fahrenheit and with normal engine temperature. Only vehicles with the manufacturer Zahnradfabrik Friedrichshafen (ZF/Bosch) standard steering gear are affected. The issue does not affect the manufacturer Thyssen-Krupp (TKPS).

The issue only occurs with tie rods from manufacturer CTR, not from Lemfoerder. CTR tie rods can be identified by the engraving “CTR.” 

After verifying the noise complaint, remove the outer rack gear boot clamp and push the boot back to identify the tie rod maker. If grease is discolored and corrosion is found in the joint, replace both tie rods. 

Replacement tie rods are available as follows:

P/N                                       PART

32 10 6 799 960...................Left tie rod

32 10 6 799 965.................. Right tie rod

32 10 6 765 232.................. Pipe clamp

32 10 6 756 011.................. Hose clamp
