Most common Toyota services
- CV axles. Camry, RAV4, Highlander, Sienna, and Corolla front CV axles last 100k-150k miles in normal use, less in pothole-heavy or hard-cornering driving. Clicking on tight turns is the universal indicator.
- Power steering pump. Tacoma and Tundra power steering pumps wear in the 120k-180k range. Whining at idle + slight leaking at the pump are the leading symptoms.
- Rack-and-pinion. Camry / Avalon / Sienna racks develop inner tie rod wear by 100k-150k miles. Clunking on bumps and loose on-center feel are the diagnostic signs.
- Steering gear box (4Runner / Sequoia / Land Cruiser / older trucks). Older Toyota truck platforms still use recirculating-ball gear boxes. Sector shaft seal leaks are the most common failure on 150k+ mile vehicles.

Notes worth knowing
Toyota originally specified Dexron II for power steering on most applications; modern Dexron VI is backward-compatible and the standard replacement. Some newer Toyota vehicles (Prius, 4Runner 2010+, some Camry) use electric power steering and have no hydraulic pump or fluid — verify your specific model. Toyota OE numbers with embedded letters (e.g., `4960733E00`) are alphanumeric, not scientific notation — the letter E is part of the part number, not an exponent. Cross-references in interchange catalogs will match the full string.
Common questions
- Does my Prius/Camry hybrid have a power steering pump?
- Most modern Toyota hybrids (Prius from 2004+, Camry Hybrid 2007+, RAV4 Hybrid) use electric power steering with no hydraulic pump or fluid. The Camry non-hybrid still uses hydraulic on most years. If your reservoir has no fluid cap or the engine has no belt-driven pump visible, you have electric steering.
- How long do Toyota CV axles last?
- Typically 100,000-150,000 miles on most Toyota applications. Higher-mileage examples are common — Camrys and Corollas routinely reach 200,000+ miles before the original CV axles need replacement. AWD RAV4 and Highlander axles wear at similar rates on both axles.
