Frequently Asked Questions About International 4700-4900 Steering Parts & Acc.

What years and models are these steering parts compatible with?

Our International 4700-4900 steering parts are designed to fit International 4700, 4800, and 4900 series trucks manufactured from 1989 through 2002. However, specific components may have narrower compatibility ranges. Always check the individual product description for exact year ranges, as some parts changed mid-production year. For example, power steering pumps differ between pre-1995 and post-1995 models due to hydraulic system updates.

What are the most common signs I need to replace my steering components?

Watch for these warning signs: excessive play in the steering wheel (more than 2 inches of movement before wheels respond), grinding or whining noises when turning, steering wheel vibration at highway speeds, uneven tire wear on the front axle, or difficulty maintaining lane position. If you notice power steering fluid leaks around the gear box or pump, address these immediately as low fluid levels can damage the entire system.

Can I install these steering parts myself, or do I need special tools?

While many steering components like drag links and tie rod ends can be replaced with standard shop tools, you'll need specific equipment for proper installation. A pickle fork or tie rod separator is essential for removing old parts without damage. Torque specifications are critical - steering components require precise torque values (typically 185-300 ft-lbs for major components). Power steering pumps and gear boxes often require pulley pullers and pressure testing equipment. We recommend professional installation for steering gear boxes and columns to ensure proper alignment and safety.

What's the difference between OEM and aftermarket steering parts for my International?

OEM parts are built to original International/Navistar specifications and typically carry higher price tags but ensure exact fit. Quality aftermarket options from manufacturers like TRW, Moog, and Spicer often meet or exceed OEM specifications at lower costs. Key differences include warranty coverage (OEM usually 1 year, aftermarket varies from 1-3 years) and material composition. For high-wear items like tie rod ends and drag links, premium aftermarket parts with greaseable joints often outlast sealed OEM versions.

How often should I service my International 4700-4900 steering system?

Inspect steering components every 12,000 miles or during regular DOT inspections. Grease all fittings monthly if your truck has greaseable joints - this simple maintenance can double component life. Power steering fluid should be checked weekly and changed every 100,000 miles or 2 years. Pay special attention to steering shaft u-joints and couplers, as these wear faster on trucks with high idle hours. Keep detailed records of any steering play measurements during inspections to track wear patterns over time.
