Dorman - OE Solutions Power Steering Pump Pulley P/N:300-123
Dorman 300-405 power steering pump pulley for the 1990-1995 Toyota 4Runner and other vehicles carries the V-belt drive from the engine to the power steering pump.
Belt squeal, rust or nicks in the groove, or visible damage to the pulley can mean it is worn, though the V-belt and the power steering pump can be behind the same signs.
As a power steering pump pulley for the 1990-1995 Toyota Pickup and the 1990-1995 Toyota 4Runner, it is a direct replacement for the original pulley, and either vehicle takes one.
