"Drilling wheel studs or lug nuts"


          

My son lost the key to his wheel locks(apparently NOT Lincoln). I bought a special socket to try and remove them but the lug nut holes in the wheels are too small for the socket diameter(custom wheels).

I was able to pound on a socket and get two of the lugs off but two remain and defy all attempts to remove them. One rear stud and lug are really mauled from trying to chisel it off.

I think my next step is to drill the nuts or the studs. One is on a rear wheel and the other is a front wheel.

What are the best drill bits and procedure for this work?
Any other suggestions?

Thanks.

Oh what fun...I've never had to do anything as big as a stud, just smaller stuff. But, Craftsman(sears) has a bolt or screw extractor set. It's done everything I've ever needed it to. They're kinda square and just lock on once you drill it out to try and twist it out. It may not work for what you're doing since studs aren't actually threaded into the hub. You can also find reverse thread sockets that twist on over the lug and catch on and twist it off, but I doubt it would fit inside your hole on the wheel, but just another idea. Anyway, you may look into that extractor set, it may not be what you need but thats my best idea. I had to order mine online, my Sears didn't have them in stock. I think they were about $25 if I remember correctly.

Good Luck!!

I believe the studs are a fairly hard metal so you might be using a few drill bits. I would suggest trying to find an industrial supply business and trying to buy cheap drill bits where you can buy several for cheaper than you will get at retail.

Cobalt bits are harder and might work better. I'm not sure, though.

For actual drilling, you need to drill a pilot hole with maybe a 1/8" bit. You might even need to start with a 1/16" bit.It will be important to keep the bit centered in the stud. What you are trying to do is drill down thru the center of the stud with the pilot bit and then follow up with larger bit that will be diameter of the threads of the nut so that the nut will fall off when you drill down.

Once you have the nut off so you can remove the wheel, then you need to hammer and punch the stud from the hub.

As a general rule, studs are not too hard to hammer out of a hub, but I had a situation once with a friend's old Dodge where we could not drive out the stud, so we removed the hub from the car and still could not get the stud to budge even with an arbor press. We ruined the hub.

I might suggest that if the car is still drivable, it might be best to find a general machine shop and see if they can do the job.

I bought the sears extractor set. The heads of the extractors were too big to fit into the lug nut holes in the wheels.

I will next try the cobalt drills. What drill speed would be best?

The front locking lug that won't come off may still come off with the other set of stripped lug sockets I bought. They are too large to fit in the wheel but I may be able to grind down the outside of the socket to fit. If that does not work I may weld a bolt to the locking lug and try and remove it that way.

Does the rear have replaceable studs or are the studs a part of the rear hub? How about the front?

Can the front or rear hubs be removed with the tire still attached?

Thanks for your help.

Concentrate on drilling for accuracy. Not speed.

They are replaceable studs.

I don't see how. Assuming you could even get into the hub nut on the front, the brake caliper would hold up the rotor.

have access to a welder? weld a bolt to the offending nut and remove.

attach the ground to the bolt you weld on there, don't want to pass the current through the bearings or the threads, and remove the battery cables before you weld on a car.

You can also cut a slot in it with a cutoff wheel and use an air chisel to turn it.

Also copious, stupid amounts of PBlaster are applied whenever I have a case like this...

The custom wheels prevented me from being able to get at the bolts or the nuts, they were too far into the wheel holes where the bolt and nut sit inside of.

I tried everything and spent a BUNCH of money on all kinds of drilling and grinding bits.Not to mention the toll this job took on my impact and regular sockets and ratchets. I have a real pile of broken tools to take back to Sears.

In the end I drilled, ground with stones on a air die grinder,and used a air chisel,it took many hours to get the two locking lugs off.

And I thought the blend door was a pain.

Glad to hear you finally got those out of there!

If I buy a car with those on there, it's first order of business to get rid of them.

My take on those lock lugs is this: If you live in such a rough place where you always worry about someone stealing your wheels, Move Somewhere Else!
