Frequently Asked Questions About Mack CV/GU Truck Steering Parts & Acc.

What years and models of Mack CV and GU trucks are these steering parts compatible with?

Our steering parts are designed to fit Mack CV models from 2000-2019 and Mack GU models from 2003-2015. However, compatibility can vary based on specific configurations like engine type and chassis options. We recommend checking your VIN or calling our technical support team at 1-888-875-7787 with your truck's serial number to confirm exact fitment before ordering.

Are these aftermarket steering components as durable as OEM parts?

Most of our steering components meet or exceed OEM specifications. We carry both economy and premium lines - economy parts typically use standard grade steel and rubber compounds suitable for average use, while premium options feature forged steel construction, greaseable joints, and heavy-duty rubber boots designed for severe service applications. Look for parts marked "HD" or "Heavy Duty" if you operate in harsh conditions or need extended service life.

Do I need special tools or alignment after installing these steering parts?

Basic steering component replacements like tie rod ends, drag links, and pitman arms typically require standard hand tools plus a ball joint separator or pickle fork. However, you will need a professional alignment after installing any steering linkage components to prevent premature tire wear and ensure safe handling. Some parts like steering gear boxes may require specialized pullers and should be installed by experienced mechanics.

What's the difference between greaseable and sealed steering joints?

Greaseable joints feature zerk fittings that allow periodic lubrication, extending service life but requiring maintenance every 3,000-5,000 miles. Sealed joints come pre-lubricated and maintenance-free but typically need replacement sooner. For commercial applications with regular PM schedules, greaseable components often provide better value. Weekend warriors or low-mileage applications may prefer the convenience of sealed joints.

How can I diagnose which steering component needs replacement?

Common signs include excessive play in the steering wheel (more than 2 inches of free play), wandering or pulling while driving, uneven tire wear, or clunking noises when turning. To isolate the problem, have someone turn the steering wheel back and forth while you inspect each joint for movement. Any visible play in tie rod ends, ball joints, or the pitman arm indicates replacement is needed. Steering gear boxes may show signs of leaking fluid or excessive play at the input shaft.
