Detailed Description

Mevotech GS40030 is a rack and pinion bellows kit used to seal and shield the steering rack area on front-steer vehicles. The rubber construction provides the flexibility needed for steering movement while helping keep contaminants away from internal steering components. This part is a practical choice for Ford F-150 front applications, Ford Explorer front applications, and Mercedes-Benz models that use a front rack and pinion bellows setup. It also cross-references Mevotech Supreme MS40030 for the same application.

Compatible vehicle coverage includes front applications such as 2009-2018 Ford F-150, 2006-2010 Ford Explorer, 2015-2017 Ford Expedition, 2007-2010 Ford Expedition, 2015-2017 Lincoln Navigator, 2007-2010 Lincoln Navigator, and multiple Mercedes-Benz front steering applications including ML, GL, R, SL, CL, and S-Class models. The GS40030 part number is also referenced in steering service searches for Ford F-150 rack and pinion bellows kit replacement and Mercedes-Benz front steering rack boot service.

Installation Notes and Tips

Verify the vehicle’s front steering configuration before ordering and compare the original bellows dimensions to the GS40030 specifications. Inspect the rack housing, tie rod area, and adjacent seals for wear before installation. Proper seating at both ends is important to maintain a secure seal and consistent steering movement.
