How do you replace the studs on a 1999 jeep wrangler?

Answer 1

Lug studs are pressed in to the hub, to remove a broken one use a punch and hammer to drive it out the back side.

If it is not broken but stripped just a good whack with a hammer should do.

To remove the stud without damaging it stack 2 nuts on the stud, tighten them against themselves flush with the end of the stud and hit with a hammer.

To install feed the new stud in from behind, stack some washers if there is a gap in the threads or thread a nut on and tighten until the back of the stud is flush. ( there may be notches in the hole that the stud matches up to, the stud should be splined.)

Find the correct torque value for your vehicle and torque the studs to that amount and no more.

Many tire shops use impact wrenches to tighten the lugs and pay no attention to how tight they get them and that is how many get broken, a good shop will use an impact to snug the nuts on and then tighten them with a torque wrench. ( low setting on the impact wrench )
