Redrilling wheel hubs - stud type
rodgling - 8/1/13 at 03:43 PM

I've got some new wheel hubs that I intend to get redrilled from 5x120 to 5x114.3 to suit my wheels at the front. While I'm at it I'm also going to get studs put in.

I can either get the hubs drilled & tapped, then screw in the studs, or I could get the press-in stud type.

Anyone got any thoughts on which is better/easier to do/stronger/safer? Does it really matter?

I would tend to go for press in studs but thats just my personal opinion. Is there no practical option for changing the wheels to match the hubs though ?

I think modifying the hubs will work better, the alternative would be welding up the wheels then getting them redrilled to a bigger PCD, so there might not be enough material to redrill 6mm further out.

With the press-in type is it just a case of drill a hole of the right size, then press the stud through from the back?

Thats what i would do but double check in case there is a reccomendation the holes be made very slightly conical.

Personally I'd rather have the push in type as they have a shoulder to prevent pulling out. But they can be an issue if the wheel nut seizes as they can rotate in the hub, which is a nightmare.

I bought my car part built and the previous owner redrilled the hubs from 5 stud to 4 stud. Both ford I think. He was a bodger and I think he just banged the brake disc on the hub and rotated it until the holes in the disc missed the existing holes, then drilled away. I have used the press in type of studs a bloody hell agree they a tight fit. Some will not pull any tighter even with a nut tightened with a breaker bar. Don't know if these are going to cause me probs when I finally get it on the road.
