Designed for dependable, everyday steering, the TERREPOWER (formerly BBB Industries) N511-0104 is a new power steering gear that converts steering-wheel input into the motion that turns the wheels, with power assist to reduce steering effort. It is listed for several Toyota model entries, among them the 1989-1991 Toyota 4Runner, the 1989-1991 Toyota Trucks 4Runner and the 1985-1991 Toyota Trucks Tacoma & Pickup, and it is a direct-fit replacement for the listed applications.
The steering gear sits between the steering column and the steering linkage, where it translates the driver's input into wheel movement. Signs the steering gear may need replacing include power steering fluid leaking from the gear, excessive play or looseness in the steering, heavy or binding steering, or noise when turning. Other components can cause similar symptoms, so diagnose the cause before replacing the gear. If a failed steering gear is the cause, the N511-0104 replaces it.
