Damaged wheel studs should be replaced as soon as possible. When a stud is stripped out or broken, it can’t fully perform its function of holding the wheel on the car. Fortunately, with a few basic tools, you can do this job yourself and save some money over taking it to a mechanic. Make sure the replacement wheel studs you purchase are made specifically for the 1996 Buick Regal’s rear wheels, since stud size varies from one model to the next.
Tools Used: Tools, Jack, Jack stand, Tire iron, Spare lug nut, Hammer, Washers, Impact wrench
Replace Rear Wheel Studs
Raise and support the rear of the Buick. Place a jack next to the wheel and lift until there is room to slide a jack stand under the frame. Gently lower the Buick onto the stand. Unscrew each of the five lug nuts on the Regal’s rear wheel using a tire iron. Pull the wheel off the car. Identify the damaged wheel stud and screw a spare lug nut onto the tip of it. Tap the stud out of the hub with a hammer.
The lug nut will prevent the head of the stud from deforming and widening under the force of the hammer, potentially trapping the stud in the hub. Once it has been pounded free, remove the stud from behind. Insert the new stud the same way the old one came out. Press it in as far as it will go. Slide a stack of flat washers around the stud. Place a spare lug nut on the stud and hand tighten it until it contacts the washers. If it runs out of thread before hitting the washer stack, insert more washers and try again.
Continue turning the lug nut. An impact wrench is ideal for this job, but a tire iron will also work. Watch the head of the stud closely. When it touches the back of the hub, stop tightening. Over-tightening the nut can damage the stud. Take off the nut and washer stack. Put the wheel back on the Buick and replace the lug nuts. Jack the car up just enough to remove the jack stand, then lower the car. Firmly tighten each lug nut. Since the stud may settle further into the hole over time, tighten the nuts again after a short drive.
