Service bulletins for the 2020 Ram 1500

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

90044192022-06-27. Service bulletin. STEERING; STRUCTURE. SCREW, Hex Flange Head, Rack and Pinion Gear to Frame NEW MOUNTING BOLTS ARE REQUIRED WHEN EPS GEAR IS REPLACED. The steering gear mounting washers between the gear and frame were eliminated, and threads internal to the EPS mounts were repositioned which may cause the old bolt (or new bolts manufactured prior to 7/31/2021) to bottom out prior to achieving torque which can cause an NVH issue. For a new EPS gear (with mounting washers eliminated) please use 06510880AA bolts manufactured after 7/31/21). New bolts have a shorter shoulder length (approx 130mm) than bolts made prior to 7/31/21 (approx 140mm).
