1990 Sentra How it remove and replace lug studs on front wheel
Daughter's boyfriend removed driver's side front wheel on 1990 Nissan Sentra coupe and did not retighten the lug nuts, so, the wheel came off. The lug studs threads were damaged. I loosened up the lug studs, but have no idea how to remove lug studs from the hub. The hub appears to be pressed into the front end assembly. The hub will not separate from the main part of the front end. I need to separate the hub from the rest of the front end to remove the old studs and install the new studs.

remove wheel, brake assembly & rotor. rotate to where the broken stud is in the opening where the brake assembly was. drive the broken stud out of the hub flange. then install the new stud by stacking washers on the new stud and tighten the lug till it pulls the new studs flange tight against the back side of the hub. remove lug and washers , reassemble .
First remove wheel from car. Next take large hammer and drive whats left of lug out, you may need to use a punch if sheared off below hub hight. Now insert new lug stud in from back side of hub and use a open style lug nut (like those you see on old cars without nice wheels) and put on upside down, flat side towards hub. tighten up by hand then use socket to tighten down untill stud is pulled in all the way. In some cases you may need to use a few washes under nut to give enough room for shank on stud.
Remove wheel, brake caliper and rotor. Give the broken lug a good shot with a decent weight hammer and drive it out of the hub flange. Put new stud into hole, place a stack of washers on it and place the lug nut on backwards (flat side in) Use oil on the threads to prevent binding, tighten lug 'till stud is seated, replace everything you removed.
I assume that you are referring to the wheel studs and if so you will have to remove the wheel, the brake caliper, the brake caliper stand and the brake rotor. Drive the old stud out with a hammer. Make sure you purchase new lug nuts with the studs. If they are the acorn style, buy one that is not to help with installation. Slide the new stud in the hole from the rear of the flange, install some washers for clearance of the stud shoulder. Install the non acorn style lug nut on the stud backwards. Using a impact gun, pull the stud through. Remove the backwards lug nut and washers.
You will have to remove your wheel hub, by removing the center cap, then removing it's retaining nut (it may have a cotter pin, or a crimped nut that you have to bend up to remove it). You will need a vise to press out the stripped stud. Use a socket that's a little larger than the stripped stud so the vise will press it out as you tighten it. To press in your new stud, use the same socket on the opposite side so the new stud presses into place when you tighten it. It's really a easy repair, but you do have to have the tools to do it. As long as you have a decent set of hand tools, and a vise, you will be just fine.
I hope this helps you, and I wish you luck on your repair.
The first step in wheel stud replacement is to remove the old one. On almost every car, this is done by taping them out from the threaded side
Rotate the hub so that the back side (flat, on the back side of the hub) will not smash into something when you tap it out.
You will need a heavy hammer and safety glasses,
Next, while the glasses are on your face, use the hammer and whack on the threaded end of the old stud to drive it out the back side of the hub. If if was broken off real short, you might have to use a punch to transfer the hammer blows to what is left of the stud.
To install the new one, place it in the hole from the back side and use a standard lug nut on the new stud screwed on backwards (flat end toward the hub) and then use the car's lug wrench to tighten the nut and pull the stud into the hub. Make sure the grooves in the hub line up with the ridges in the new stud before trying to seat it.
Once the stud is fully seated, remove the lug nut. You are done.
I usually buy a standard lug nut that fits the replacement stud to do this procedure because most mag nuts are closed on the back end. It is cheap and will save lots of time.
