you may not have to change studs if you buy the correct lugnuts.... there are several different stud profiles....some have a shoulder that are made especially for this....but to answer your question, you have to remove the brake drum to acess the wheel studs...

Keep in mind if you're mixing and matching fasteners. Avoid a situation where the end of the stud or inside of a nut line up on the "parting line" between two wheel discs etc.

Ripe situation for an accelerated failure mode.

Bigger Hammer! after making sure all five retaining screws are removed spray lots of penetrating oil in the stud holes, and all around the center hub opening while turnig the wheel by hand, making sure theres plenty inside it all the way around. Then take your biggest hammer and hit it on the outer edge rotating it between hits! If this does not loosen it call me! I'll walk you thru it, and we'le get it off!

A tip to remove the retaining screw before the head is ruined.

Heat the screw until red with a torch. Immediately remove screw with impact wrench, impact socket, and screwdriver bit.

Ed is correct. I would suggest two other things. Make certain the screw driver tip is an exact fit in the retaining screws. I avoided a lot of trouble by grinding an old chisel to the exact size of the slot and along with the impact wrench they walked out.

I also suggest when replacing them use only new ones or ones with perfect screw driver slots, and use "never seize" or the equivalent to minimize the removal effort next time.

Why would anyone ever put screwdriver slot screws back in a brake drum after you get them out? 1/2" X 13 socket head cap screws are available from any large bolt house. Put them in and take them out with an Allen (hex) wrench.

A couple of suggestions-- 1) Pull the whole hub & drum or 2) If you must take the drum off, use phillips head brass screws to put it back on. They won't rust solid and if the head gets wrecked, it provides an exact center to drill the screw out.

Stan is correct, but why not go one further and just not replace them?

I replace mine when I pull a drum, but always wonder just what good the five puny screws do when you consider the drum won't turn because of the ten studs, and it wont fall off unless your wheel falls off first.

They must have been put there to irritate us.

"Unless your wheel falls off first!" is exactly 1 reason they are there! Another reason they are there and not on "Big Rigs" is have you ever been going down a mountain or steep grade near a "big rig" and see his brakes smoking, then a "POP" and chunks start flying out from under the wheel area? yes it happens drums will break! And because buses are designed to haul people not freight, they have these retainer screws to keep things in place for passenger safety! If a chunk were to come part way out and hang up it could cause a wheel to lock up or anything eles and could cause a wreck! These screws need to be put back on! The biggest problem I see with them is people put them in and think they are ok. When actually they don't have the drum pulled all the way upto the hub then when they put the wheel on they are sticking out against the wheel! So make sure these are on there, use plenty of anti-seize on them and yes if ya want to use Phillips or allen head screws go for it! (I prefer the allen head as you get a great grip tightening and loosening and if needed a good starter hole for a reverse thread drill to bring 'em out if ya have to, so far the reverse drill bit has always brought any stubborn ones out with out having to drill all the way out!). Just my 2 cents worth! BK
