Remove and discard the bearing but retain any undamaged shims for possible use later. With this pin removed, drive the king pin down and out of the axle and spindle. Once the dust cap is removed, unbolt and remove the tapered lock pin that is bolted horizontally into the axle housing. Remove the dust cap (soft plug) on top of the spindle by striking it with a chisel on the edge. Clean the backing plate and set aside for installation later. Check the brake shoes for wear and wheel cylinders for leakage. With the bolts removed, the backing plate will slide off of the axle, exposing the spindle, axle and king pin. ![]() Remove these, taking note that some applications will have two different size and/or different length bolts. There will be four main mounting bolts that hold the backing plate to the spindle. Also cover the end of the brake hose with a plastic bag and seal with a rubber band. When removing hydraulic brake hoses press a rubber plug into the opening on the wheel cylinder. This would include brake housings and cables on mechanical brake systems or brake hoses on hydraulic systems. This plate must be removed but anything connecting the backing plate to the chassis must be removed first. This will expose the brake backing plate. With the hub removed, slide the inner bearing dust shield and inner race off of the spindle. ![]() Check closely for pitting in the balls or races. This is a good time to inspect the condition of the wheel bearings and repack them with fresh grease. Pull the hub & brake drum off while keeping the outer bearing from falling out of the hub. Remove the hub dust cover, cotter pin and spindle nut. Jack up the front of the vehicle and place it on good quality, four point jack stands. King pins on early Chevrolet cars and trucks require pressing bushings into the spindle and using a reamer to fit the pin to the bushings. The specific applications are:ġ931-1933 All passenger & 1/2 ton trucks (except 1933 std. Graco automatic lubrication systems can help you properly lubricate kingpin bushings, resulting in a much greater reduction in kingpin failures caused by improper lubrication.This is a new reproduction set of king pins and bushings for 1928-1939 Chevrolet cars & trucks. The cost for a kit containing bushings and kingpins can range from $500 to $1,500 and replacing them is very time consuming. However, the kingpins and tie rods can wear out extremely fast if they’re not greased on a regular basis. Nothing lasts forever, even if these parts have been greased every day. “Kingpins and bushing replacement are rarely covered under warranty, because it always relates to lack of preventive maintenance.” The good news is the kingpins have a life of 750,000 miles, so with good maintenance they would only need to be replaced once during a truck’s lifetime,” said Duane Rasmussen, Instructor, Medium/Heavy Truck Technology, Hennepin Technical College. “It’s an 8-hour job to ream the bushing and replace the kingpin. Use a dial indicator to measure, axial and lateral movement should not exceed 1/8 or. If the wheel has any play you may have an issue likely caused by a worn kingpin. Try moving the wheel left to right and top to bottom and up and down. ![]() Another way is to have a helper apply the service brake to differentiate between wheel bearing and kingpin bushing wear. ![]() Tighten the wheel bearing to eliminate any play that may be related to a loose wheel bearing. Follow truck-lifting procedures in your vehicle’s operating manual to properly lift the truck.Īfter the truck is lifted and no weight is on the axle, remove the wheels and tires. Kingpin wear inspection requires that no weight be on the axle so jacking up the front of the truck is required. An easy way to help determine a worn kingpin is to conduct a kingpin wear inspection.īefore beginning, make sure to always review and follow the axle manufacture and company maintenance and procedure manuals. Because of the potential for further damage and operator safety risks, properly diagnosing and repairing worn kingpins, bushings and tie rods needs to be addressed promptly.Īfter experiencing symptoms of a kingpin and bushing failure, additional diagnoses must be done to rule out other wheel assembly issues that may also cause similar symptoms. Experiencing these symptoms while driving may result in a shaking cab or steering wheel. You will notice signs of kingpin and bushing failure from incorrect vehicle alignment, premature and uneven front tire wear, and rough handling. Improper lubrication of kingpin bushings can cause kingpin contact points to begin to wear at the steering knuckle. ![]()
