Keep grit, grime, and moisture out of your front steering gear with the Delphi Rack and Pinion Bellows Kit (TBR4218). This front bellows (boot) kit seals the rack-and-pinion assembly, holding lubricating grease around the rack while blocking dirt and water that would otherwise wear the internals. It's a direct-fit replacement for a wide range of applications, including the 1998-2002 Honda Accord, 1999-2010 Hyundai Sonata, 1997-2001 Nissan Altima, 2003-2009 Toyota 4Runner, 2003-2009 Lexus GX470, and dozens of Audi and Volkswagen models — see the Buyer's Guide tab for the full list.
If a torn or cracked bellows is letting grease escape and contaminants into your steering rack, this kit replaces it.
