Frequently Asked Questions About Mack R Truck Steering Parts & Acc.

What year models of Mack R trucks are these steering parts compatible with?

Our Mack R truck steering parts are designed to fit R-Model trucks manufactured from 1966 through 2004. This includes the R600, R685, R686, R688, RD600, RD688, and RD690 series. Always verify your specific truck's VIN and model year before ordering, as some steering components changed between early (1966-1987) and late (1988-2004) production runs. If you're unsure about compatibility, contact our customer service team with your truck's serial number for verification.

Are these aftermarket steering parts as durable as OEM components?

Our steering parts are manufactured to meet or exceed OEM specifications using high-grade materials like forged steel for tie rod ends and heavy-duty cast iron for steering boxes. Many of our steering components feature improved designs over original equipment, such as greaseable joints with reinforced boots and enhanced corrosion-resistant coatings. Professional drivers regularly report getting 150,000+ miles from our heavy-duty tie rod ends and drag links when properly maintained with regular greasing intervals.

What tools and expertise are needed to install these steering components?

Installing most steering parts requires standard heavy-duty tools including a pickle fork or tie rod separator, torque wrench capable of 300+ ft-lbs, and basic hand tools. Steering box replacement typically takes 3-4 hours for experienced mechanics, while tie rod ends and drag links can be changed in 1-2 hours. Critical safety note: steering components must be torqued to manufacturer specifications and require front-end alignment after installation. We recommend professional installation if you lack experience with heavy truck steering systems.

How can I diagnose which steering parts need replacement on my Mack R?

Common signs include excessive play in the steering wheel (more than 2 inches of free play), wandering or pulling while driving, uneven tire wear on the front axle, and clunking noises when turning. To check tie rod ends and ball joints, have someone turn the steering wheel while you inspect for movement in the joints. Any visible play, torn boots, or grease leakage indicates replacement is needed. Steering boxes typically show signs of failure through fluid leaks, excessive play, or hard spots when turning.

Do you offer complete steering rebuild kits for Mack R trucks?

Yes, we stock comprehensive steering rebuild kits that include all tie rod ends, drag links, pitman arms, and necessary hardware for complete front-end steering restoration. Our kits are available in standard duty and heavy-duty configurations, with the heavy-duty option featuring upgraded components for severe service applications. Kits typically save 15-20% compared to purchasing components individually and ensure all parts work together as a matched system. Steering boxes are sold separately due to core exchange requirements.
