Keep road grime, water, and grit out of your steering rack with the Delphi Rack and Pinion Bellows Kit (TBR4237). This front steering bellows kit is a direct-fit replacement for the 1998-2003 Mercedes-Benz ML320, 2003-2005 Mercedes-Benz ML350, 1999-2001 Mercedes-Benz ML430, 2002-2005 Mercedes-Benz ML500, and 2000-2003 Mercedes-Benz ML55 AMG — see the Buyer's Guide tab for engine-level details. The flexible bellows (boots) shroud the inner tie-rod and rack ends, sealing out contaminants so the rack stays lubricated and protected.
