Frequently Asked Questions About International 9900/i/ix Steering Parts & Acc.

What years and models are compatible with International 9900 series steering parts?

Most steering components for the International 9900 series are compatible across the 9900i (1986-2002) and 9900ix (2002-2004) models. However, power steering pumps and steering boxes may have variations between early models (1986-1995) and later models (1996-2004). Always verify your VIN and model year when ordering steering shafts, as there are different lengths for set-forward and set-back axle configurations.

How difficult is it to replace a steering box on a 9900i, and what tools do I need?

Replacing a steering box typically takes 3-4 hours for an experienced mechanic. You'll need a pitman arm puller, 15/16" and 1-1/8" wrenches, a torque wrench capable of 185 ft-lbs, and basic hand tools. The most challenging part is removing the pitman arm and aligning the new box properly. Many customers recommend having a helper to hold the steering wheel centered during installation. Professional alignment is required after installation.

What's the difference between aftermarket and OEM steering shafts for the 9900 series?

OEM steering shafts use precision-machined u-joints and heavier gauge steel tubing, typically lasting 300,000-500,000 miles. Quality aftermarket shafts from brands like Borgeson or Flaming River offer similar durability at 20-30% less cost. Budget aftermarket shafts may develop play in the u-joints after 100,000-150,000 miles. Look for shafts with sealed, needle-bearing u-joints and a minimum 0.095" wall thickness for best results.

My 9900ix has excessive play in the steering. What parts should I check first?

Start by checking the steering shaft u-joints for play - this is the most common cause. Next, inspect the drag link ends and tie rod ends for wear. Check the steering box adjustment (sector shaft) - a small adjustment here can eliminate 1-2 inches of play at the wheel. Also verify the pitman arm isn't worn where it connects to the sector shaft. Most steering play issues involve multiple worn components, so a complete front-end inspection is recommended.

Are chrome or polished aluminum steering wheels worth the extra cost for daily drivers?

Chrome steering wheels require regular polishing to prevent pitting and corrosion, especially in winter conditions with road salt. Polished aluminum wheels are more durable and easier to maintain but can get uncomfortably hot in direct sunlight. For daily drivers, many operators prefer leather-wrapped or polyurethane wheels that cost less and require minimal maintenance. Chrome and polished wheels are best suited for show trucks or trucks garaged in climate-controlled environments.
