Broken stripped lug bolt

[Toyotamug]

Sorry if this is a repeat question, i did multiple searches on lug bolt and wheel bolt and didn't get any hits. My son has a 2003 corolla bought it used with approx 96 k on it, was helping him do a front brake job on it. I noticed on the passenger side front one lug nut was different than the others, also noticed the other 4 lug nuts came off relatively easy. The odd one fought me all the way to coming off, noticed a lot of metal filings on the threads also. Once we got the tire off i noticed the lug / wheel bolt was much shorter than all the others. I presume the previous owner must have broken the bolt and jammed a lug nut on it. So my question is has anyone here replace a broken wheel / lug bolt on their corolla before??? T.I.A. Great forum have picked up many tips. Have personally owned Toyotas since 1986. Currently have 3 Tacoma 2 w drive pick up, RAV4, and Corolla. The 1986 was a 4 cyl 4wd pickup truck, put 320,000 miles on it and had it for 18 years. Have never had to deal with a broken lug bolt before.

You will need:
Impact gun
21mm socket
Open acorn lug that is same thread as your stud.
New lug nut and stud
17mm socket
Torque wrench
Ratchet
Jack stands
Jack


If it is on the front wheel you will need to remove the caliper( I recommend to remove the caliper bracket and leave the pads attached.)

Remove the rotor

Using a hammer smash the broken hub inwards towards the car to knock it out of the hub.

Grab your new stud and pull it with your hand straight into the hole

Using your open end lug nut place it backwards( flat part against the hub) and thread it on.

Using your impact gun screw In the stud until it is seated in the hub

Remove the lug nut and install the proper lug nut.

Install the rotor and caliper

Install the wheel

Torque the lug nuts to 76 lb ft.

hardtopte72, thank you very much for the reply, i am with you on most of this but don't have access to an impact wrench. Have no air tools at all. Just curious can i pull the new lug bolt in the splines with hand tools??? I figured out after posting this question and watching some youtube videoes on the removal of caliper, and bracket and rotor and knocking the bad one out with a hammer. Just not sure i can seat the new lug bolt with hand tools.

You should be fine. The key is to just remember to use the flat part against the hub when pulling in the new stud and the knurl (spline looking part that fits the female splines in the stud hole of the hub) needs to be in enough that you can pull in the stud without it spinning.

See if the parts store has a wheel stud installer you can borrow. This makes things a lot easier. Even without it use a washer (or large nut) and grease to pull the stud through.

You can do it by hand but you'll need to keep the hub from rotating with a large prybar... or make sure the other wheel is on the ground and leave it in park (or in gear) just make sure the parking brake is set and the wheels are chocked.
