How to Replace Tire Bolts
- 1). Park your car in a safe place and on a level surface, if possible. Using a lug wrench, loosen the wheel lugs on the assembly that needs the new stud.
- 2). Raise the wheel using a floor jack and safely support it on a jack stand; then remove the tire.
- 3). Remove the brake caliper if you are replacing a stud in one of the front wheels. Use a wrench, ratchet and socket or a Torx bit socket, depending on the type of mounting bolts used on your particular model. Secure the caliper on the car with a wire to avoid damaging the brake hose. Then remove the caliper mounting bracket using a wrench or ratchet and socket. Remove the hub and rotor assembly from the axle stub. Go to Step 5.
- 4). Remove the brake drum if you are replacing the lug stud in one of the rear wheels. Remove the grease cap using a standard screwdriver. Then remove the cotter pin and nut lock using a pair of nose pliers. Remove the axle nut using a ratchet and axle socket; remove the washer and front wheel bearing. Pull the brake drum off the wheel assembly.
- 5). Press the damaged stud off the brake rotor or drum. If you do not have access to a press tool or hydraulic press, take the part to a machine shop.
- 6). Insert the new lug stud or tire bolt through the back of the brake rotor or drum. Place three or more flat washers over the new bolt through the front of the brake rotor or drum. Then thread one of the lug nuts on the new bolt using a wrench or ratchet and socket to draw the new bolt in place. Tighten the nut until the bolt seats completely; then remove the lug nut and flat washers.
- 7). Install the break rotor or drum in place. Install the caliper bracket and caliper on the rotor. Install the wheel bearing, washer, axle nut and lock, new cotter pin and grease cap if you are replacing the brake drum.
- 8). Install the tire and wheel lugs. Lower the vehicle and finish tightening the wheel lugs.
