✔ Fits these vehicles

This listing is the top seal (pinion seal) only — not the complete rack. (Driving a Titan? This same seal has its own Titan listing.)

Signs yours is failing

• Power steering fluid leaking at the top of the rack
• Whining or groaning when you turn
• Fluid level keeps dropping
• Steering starting to feel stiff

Replacing the seal early can save the rack itself — a leaking seal left alone eventually takes the whole unit with it.
