Suspension - Steering | 1983-1987 Ford 7.3L IDI

Between 1983 and 1987, Ford trucks saw some solid improvements in steering and suspension systems, making them more reliable and comfortable on the road. Power steering became more common, though it wasn’t always standard across all models. Higher trim trucks and those equipped for heavier-duty tasks were more likely to feature it as standard, making it drive much easier.

The Twin I-Beam suspension for the 2WD models and the Twin Traction beam independent front suspension for 4x4 trucks provided a smoother ride and better handling, especially off-road, although the handling wasn’t precise under heavy loads. Ford did, however, step up the game with stronger steering gear boxes and linkages for better durability, especially when hauling heavy loads.

They added steering dampers to 4WD models, helping reduce feedback and vibrations when hitting rough patches. Still, some old issues didn’t go away, like play in the steering due to worn gear boxes and early wear in tie rods and ball joints.

Steering dampers sometimes failed, leading to bump steer, and the power steering pumps could develop leaks that made steering a bit tougher. To address these challenges, consider upgrading to the Red Head steering gear box, which tightens up the steering response, and takes out the annoying play, making the truck much more enjoyable to drive.

For a more comfortable ride, the Bilstein B6 shock absorbers will do a great job smoothing things out, regardless of the terrain. If you tow frequently or tow heavy here and there, you should consider the LongHorn Fab standard-grade traction bars. These bars will improve traction, prevent axle wrap, and give you more control over the truck and its load.

Because of the age of these trucks, oftentimes the suspension parts wear out quicker being in the constant elements. Handling every load, the leaf shackles can get worn out quickly. Sulastic’s rear leaf shackles can make a huge difference in how your truck handles loads and soften the bumps and vibrations.

Like many trucks on the road today, the 6.9L relies on a solid axle with leaf springs that are meant for heavy duty tasks. However, their tolerances are often tested with heavier loads. Then, when unloaded, drivers are met with subpar ride quality. This system is great until some of these common issues arise.

The sagging of the leaf springs and the rough ride can all be fixed with a simple solution. Many owners choose to improve this by adding air spring assist kits like the one from Pacbrake. These kits will assist the leaf spring with more rigidity keep the truck when leveled and can be adjustable for loaded and unloaded drives.
