Built with inner tie rods included and seals supplied, this assembly is intended for steering repair where the original rack shows wear, leakage, or inconsistent steering response. PWR states that its racks and gears are tested for leaks, pressure, noise, and function, helping confirm the unit is ready for installation on the listed Chevrolet Colorado and GMC Canyon platforms.

What This Part Helps Address

• Steering fluid leakage from a worn rack and pinion assembly
• Excessive steering play or loose steering feel
• Noise during steering input from internal wear
• Uneven or inconsistent steering response
• Failure of the original hydraulic steering gear

Installation Notes and Tips

Verify chassis package, VIN breakpoint, and engine/application notes before ordering. This assembly does not include mounting hardware, mounting brackets, or outer tie rods. Confirm the inlet and outlet line fitting size and gender match the vehicle before installation. A professional alignment is recommended after steering component replacement.
