Replace a leaking or worn steering rack with the Atlantic Automotive Engineering (AAE) 3578N, a new, 100% tested Toyota Sienna rack and pinion. It is a direct-fit replacement for the 2004-2010 Toyota Sienna and is designed to match or surpass OE specifications for performance, fit and function.
This hydraulic power steering rack and pinion assembly is built with OE-quality components. Steering issues affect how safely a vehicle handles, so they should be diagnosed and repaired as quickly as possible.
- Inspection and testing: Every unit is inspected and hydraulically tested in the USA to confirm proper operation and fitment.
- Inner tie rods and bellows included: Supplied with inner tie rods and new bellows secured by OE stainless steel clamps, which help keep dirt and debris out and guard against premature failure.
- Heat-treated bar: An upgraded bar is heat treated to help resist premature failure.
- No core charge: AAE new power steering racks are sold without a core charge.
Signs a steering rack may need replacing include fluid leaking at the rack, stiff or uneven steering effort, and excess play at the steering wheel. A power steering pump, hose or other steering component can cause similar symptoms, so diagnose the cause before replacing the rack. See the Buyer's Guide tab for engine-specific fitment.
