TERREPOWER 503-0156 steering gear for the 1999-2002 Chevrolet Astro and other vehicles turns steering wheel rotation into wheel movement with power assist. This is a remanufactured power steering gear.
Loose or vague steering, hard turning or fluid around the gear housing can mean a steering gear is worn. These signs alone do not prove the gear is at fault, since a leaking hose or a weak power steering pump can produce similar trouble. Have steering problems looked at promptly.
This steering gear fits the 1999-2002 Chevrolet Astro and the 1999-2002 GMC Safari. A 1999-2002 Chevrolet Astro takes one, and so does a 1999-2002 GMC Safari.
