Beck/Arnley Rack and Pinion Bellows Kit P/N:103-3153
Keep the left-side steering rack sealed against grit, road spray, and moisture with the Beck/Arnley Rack and Pinion Bellows Kit (P/N 103-3139). This left-position, application-specific boot kit drops in on the 2005-2013 Subaru Forester, 2005-2007 Subaru Impreza, 2010-2019 Subaru Legacy, 2010-2019 Subaru Outback, and the 2015-2021 Subaru WRX and WRX STI — see the Buyer's Guide tab for the full engine-level list.
The bellows boot encloses the tie-rod end of the rack and pinion assembly, holding steering lubricant in while keeping dirt and water out. A cracked or torn boot lets contaminants reach the rack, which can accelerate internal wear — if a failed boot is the cause, this kit replaces it.
