Wheel studs are bolts that are connected to the wheel part of a vehicle. These bolts are fastened by "Lug nuts" which are used to keep the wheel stud in place. There are things that should be kept in mind in replacing your old or worn off wheel studs:
1. Get your tools ready for wheel stud replacement:
- a 17mm regular socket wrench or and adjustable wrench.
- a torque wrench (optional), you could use the wooden head hammer or the regular sized wrench if you have one as a substitute.
- A small wooden head hammer or a steel type hammer.
- A set of extra lug nuts in case you might need to replace the old ones in fastening the wheel studs.
- A set of new wheel studs.
2. Safety precautions should be applied first before you remove the wheels of the car.
- You could use a pair of thin rubber gloves to keep your hands from acquiring grease and dirt. It could also help in preventing your tools from slipping and improves your grip on handling the tools.
- Put a jack on the suspension shafts first and make sure that it is properly placed to avoid accidents. You can add an additional jack for support in case the main jack fails.
3. Now that you are ready for wheel stud replacement, start by removing the wheels first. If the wheel has a plastic hub, carefully remove it so you can unscrew the lock nuts using a socket wrench. Get a plastic container for collecting the removed locknuts so you would not lose them. You can now remove the wheel after the lock nuts are taken out.
4. After taking out the wheel, you may remove the caliper and brake pad. Flip it upwards to release the brake pad. Then locate the bolts that hold the calipers and take them out. You can find those in the back part of the rotor (a circular metal plate referred to as a "disk brake").
5. Without the calipers locking the rotor plate, you can now easily remove the disk brake. Place your hand at the back part of the rotor with your other hand holding the disk for support. Then carefully slide the disk brake towards you in able for the whole rotor part to slide outwards. After removing the rotor, place a cloth or a piece of newspaper under it to avoid damaging the back side of the plate.
6. Now, locate the studs which are connected to the rotor base and use a wooden hammer to remove the wheel studs. If you are using a steel type hammer or an extra wrench, wrap a piece of cloth around it so you would not damage the studs. Carefully strike the hammer or the wrench on the tip of the stud to push it inwards. Tap the stud gently to loosen it a bit.
7. Remove the old wheel studs one by one. Insert a new wheel stud part in place from where you removed the old stud. Make sure that the new wheel studs fit perfectly. You might need to tap the back part of the new wheel studs to double check.
8. Put the disk brake back together with the brake plates and the caliper. Tap the caliper downwards with a hammer to lock it in place.
9. Put the wheel back and lock the bolts.
10. Now you have successfully replaced the wheel studs.
