Hi, I ran into a problem while installing new rotors! The stud holes are to big, and when I pound them in they are tight in the hub but not on the rotor, so when I grab the rotor I can move it back and forth a little. I measured the hole in the old rotor and its almost 1mm smaller and the studs fit tight.
I went back to the parts store and they are supposidly the right rotors, they called there tech line and the hole sizes are correct, yet when he tried a new stud off the shelf it was sloppy also!
At the parts store we also checked a rotor off of a 92 as it listed a different #.
The holes were smaller and the studs fit snug! The funny thing is the 92 and the 95 call for the same studs!(so why are the hole sizes diff in replacment rotors?)
The discs were thicker though so I couldn't use them.
First off, the rim is centered by the wheel studs, and is not hub centric. Secondly, DO NOT WELD ON YOUR HUB OR YOUR ROTORS. This could potentially cause problems with the rotor itself, and more importantly the wheel bearings from the heat from welding, and due to that both materials are cast the bead wont stick worth a **** and could cause them to crack. I would go to ford and see if they have the proper wheel studs to fix your sloppy stud problem. Also when you pound them in, also tighten them up with the lug nuts to make sure they are seated properly.
the rotor is tight in between rim and hub . Look at the goofy hub set up on 88-89 trucks where outer hub comes off. Those rotors "At least the one I had new" was held on with small clips on studs. I'd check other places and check studs to the splines my not be long enough. But you should be fine as 90% of car/trucks today you can remove hubs without messing with studs.Good luck
