Important fitment Notes: There are two main versions of steering gears for these year vehicles, and we've seen many with either version. The best way to get the correct version is to count the blanks, the big gaps between splines, on the sector shaft. The sector shaft is the shaft passing through the side cover of the steering box, with a pitman arm attached to its outer end. This shaft with have either 3 or 4 blanks.

Does turning your steering wheel lead to a suspended disbelief moment before your truck finally reacts? In addition to complete steering failure and visible leaks, there are several other common symptoms of a compromised steering box. These include grinding noises, binding in the steering wheel, and steering looseness. When the internal components of the steering gear wear out, the vehicle's steering may feel imprecise and floaty, leading to the vehicle drifting or pulling to one side. Turn back time with a new, not refurbished, steering gear box, with no core return, and industry leading 3 year warranty from USA Standard Gear.
