The need to replace the hub stud comes only after careless handling. Usually, when the tightening force of the wheel nut is significantly exceeded, the stud with a large thread breaks off, and with a small one it becomes unusable.
Necessary
- - keys set;
- - a hammer.
Instructions
Step 1
Remove the wheel, then use the wrenches to remove the brake caliper guide bolts. Take this opportunity and inspect the guides and brake piston anthers, and also check the condition and presence of grease on the guides. Remove the caliper from the brake pads and suspend it with thick wire. Hang the caliper on the spring coils so that it does not interfere with your further actions.
Step 2
Remove the brake pads. Inspect them for uniformity and wear. Dismantle the brake caliper caliper so that the brake disc can be removed. To do this, unscrew the 2 fixing screws using a socket wrench and suitable extension pieces.
Step 3
Remove the brake disc. It is usually easy to remove it from the hub by lightly hitting the edge with a wooden mallet and pulling with your hand. On some car models, eg Nissan "Wingroad", you will need to unscrew the 2 countersunk fixing bolts. These bolts serve to secure the brake disc to the hub during wheel changes and protect the assembly from dirt getting between the disc and hub. Take a heavy-duty impact screwdriver, place it in the head of the bolt, free of dirt, and apply a few hard blows with the hammer to the end of the screwdriver. Thereafter, the bolts are usually easily loosened. You can additionally apply a penetrating lubricant to the bolt. It will make it easier to free the threads from dirt and rust.
Step 4
Apply a few hammer blows to the butt of the damaged stud. She will leave her seat with some resistance. Rotate the hub by hand until the head of the stud is aligned with the slot in the apron of the brake disc. If this slot is not there, remove the apron. Usually it is mounted on 3 or 4 bolts, which can be turned off without any problems.
Step 5
Remove the damaged pin and insert a new one in its place. Align the splines of the stud with the splines in the hole in the hub. Screw the wheel nut onto the stud thread until it stops, then pull with a wrench. Press in the stud as far as possible. If necessary, select a bushing of the correct length and place it between the nut and the hub. For less resistance, lubricate the threads with bearing grease.
