When you notice that the wheel nuts on your tire don't stay tight but are loose each time you check them, you need a new stud and nut. You can replace the wheel stud in your Chevy Impala if you have the right equipment, a little knowledge about your automobile and strong hands.
Purchase a new stud. You need the same size stud when you replace the wheel stud on your Chevy Impala. There's an alternative, shorter stud made by GM that you can use to make insertion easier.
Check in your trunk under the spare tire for the jack and jacking tools. You need to make sure you block the tires when you jack up the vehicle.
Raise the Impala on the jack and then remove the wheel. Take off the caliper but leave the brake line on it. Use a wire to hold it and don't let it hang by the brake line. Remove the rotor. The rear brakes are either disc or drum. If you have drum brakes, remove the drum.
Feel behind the hub to see if there's a spot where there's adequate room to remove the stud and line the stud up with the space. If there's no room, you either need to remove the hub and use a vise to remove the stud, or saw off the stud and replace it with a shorter one.
Smack the stud with a hammer to drive it out the back. If you sawed it off, you may need to put a rod on the stud and smack the rod. Pull the stud out the back and push in a new one.
Use wheel bolts to tighten down the stud. Put them on the stud with the angle outward. As you tighten these down, they pull the stud through the hole. Check the back and stop when you see the head flat against the hub. Use an impact wrench if you have one to make the job easier
Remove the bolts that you put on when you replaced the wheel stud on the Impala. Put the assembly back on in the reverse order and tighten down the wheel nuts.
