Trying to replace 5/8-18 lug with 1/2-20.

Hubs came with rear end. But replacing wheel studs and cannot find anything that works for weeks.

Which option is easier?
1) enlarge feont lugs to 5/8 and machine 6 wheels.

2)reduce rear lugs to 1/2 to match front and wheels?

It’s gonna be easier to put 5/8” studs in your front hubs and drill your wheels. Effectively it’s kinda hard to put a 1/2” stud in a 5/8 hole.

Haha i literally laughed when i read this. Honestly not sure if you were trying to help or making fun* of me. I agree a .500 stud does not fit in a .625 hole.... duh. But there is such a thing as a "shoulder" with knurls that is .625 then steps down to a .500 thread.... i guess that was my question, where do i find that lug.

What kind of vehicle? If its a decent sized truck, even if you can find such a stud, IMO its still better to just upgrade everything to 5/8.

Haha. No, not trying to make fun of you, just offering the easiest way to go about things. I’m assuming this is for the ranger you Posted in another thread? Depending on what front hubs You are using you can drill and press them in yourself. I’m sure you could find a shouldered 1/2” stud but like you said you’ve been looking for weeks. If your set on going this route contact specialty fastener, they might have something like this.

Yes its for the same truck.

Im using D44 front knuckles and spindal from full size Bronco.

I think ill just upgrade to 5/8. Any idea how difficult/cost to mill a wheele to accept the 5/8?

D44 hubs are easy enough to do yourself. You have to drill the hub and rotor and make sure you get a stud with enough knurl on it to “grip” the rotor as well. As for the wheels you can drill them yourself, depending on what taper lugnut your going to end up with. I’ve done it many times it’s very easy. You can do it by hand if you must or a drill press makes things easier. There used to be a wheel guy in town, for a set of wheels, he would charge us $100 to drill and machine for whatever lug we were using. Great deal if your not comfortable doing it yourself and can find someone close to you who will do it.

Arp do make them. They have a stud that has 5/8 knurl, 1/2 unf thread and they are 3 inches long high tensile. Think they are called ford wheel studs. Bit like the picture below.

I have replaced 5/8 sutds with 9/16 before but couldn't find any 1/2" with large enough knurl to match the 5/8" studs. Benefit of 9/16" is they are bigger and don't have to redrill wheels at all.

If this vehicle is going to be raced keep in mind that the flat tire change in the heat of the moment could cause problems. A Milwaukee 1/2” electric impact will give those wheel studs hell and more than likely stretch them. A 5/8” stud......not so much. Do it once and be done.

My issue isn't my wheel coming of with 1/2" studs, I've never beaten on anything that hard...you guys must be going WAY bigger than I am! Actually its the shoulder length that's the issue, .9, knurled .625 by 1/2-20 AND 3"! Maybe I'll take everything apart & go 5/8s.......

I ended up drilling out the hub and rotor and pressed in the studs i wanted. I used a reemer from mcmaster carr. Damn things are pricey. All came out aligned and straight.
