Quick answer

MCI noticed that some customers operating in severe duty environments were experiencing the exterior U-Joints of the lower steering shaft binding due to corrosion. Because of this, MCI has developed a new re-greaseable U-Joint service kit (NF PN: 6505981) to replace the existing greased for life U-Joint on lower steering shafts. Rework instruction and preventive maintenance guide are provided below. Following this procedure and preventive maintenance will increase the life of MCI lower steering shafts.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
