DIY: E9X M3 Wheel Stud Install

Butkolrpi · 11-05-2017, 05:20 PM

Just put together a short video to show wheel stud installation on an E9X M3. I already have Stoptech brakes installed but the process is basically is basically the same for stock brakes. Please comment.....I tried a different video format.

The studs are bullet nose studs from Turner. I really like the setup. It will be especially handy when I switch back to summer wheels and tires.

Why did you take the rotors off?
You can install without that step..

It may help with seeing the thread engagement into the hub.

Not sure why... they thread in just like your wheel bolts.

Sorry, I don't mean to sound like a jerk with the questions and comments.
I do appreciate you taking the time to post this DIY vid, but I was concerned that the level of complexity would scare some other noobs away from trying this themselves.
As a track rat I have done this job many times.

One safety note.....
Its hard to tell from your vid, so I'll assume that the floor jack at the front wheel was replaced with another jack stand?

Regarding the tap to chase the threads.....

Normally not necessary as these are the same threads that your wheel bolts go into, so they should be in good shape.
If they are nasty enough to require a chase tap, make sure you use the right one.
The threaded holes in the hub are straight cut (not tapered) so use a straight cut tap and be VERY careful not to damage the hub threads.

FWIW here is my normal procedure.

Prep work

If you don't have a lift, place the car safely on stands.
Remove wheels (you can do one corner at a time if that's easier for you)
The hub holes should be pretty clean already, but I use a spiral wire brush in the threaded holes to make sure.
Wheel bolts are normally installed dry, but if you have used anti-seize on them be sure to use a cleaning agent
to degrease the hub holes when you use the wire brush (brake cleaner) so that the Loctite works properly.

Installation

Apply Loctite to the stud threads but don't go crazy with it, it doesn't take much.
Then turn them in by hand. (should go easy)
Tighten them down.
There are two basic types of studs.
Bullet nose which requires double nuts to lock on the thread, or studs with built in Allen socket (or something similar)
They just have to be good and snug (apprx. 15 lbs).
All you are doing is bottoming out the last thread on the stud.

Put your wheels back on and your done.

It takes more time to jack the car, place on stands, re&re the wheels than it does to actually install the studs.

I have done some studs that don't have well defined stops on them and could be driven in too far -- these were not very high quality studs. I have also installed some studs into hubs that aren't perfect and could not tell how far in they were with the rotor installed because they weren't going in well and I did not have a thread chaser.
