Hello, I ordered new rotors and wheel studs thru Rockauto for a 76 f250 4x4. The holes in the rotors are quite bigger then the studs? My old rotors that i pressed the old studs out of are slightly bigger also, but better? Is that normal? I was excepting a press or slide fit?
Sounds like you got the wrong wheel studs, you should have to PRESS in the wheel studs. Or use the impact gun and the stack of washers trick to get them seated. Rock Auto strikes again. Do you have 1/2 or 9/16 wheel studs?
I have never had any luck getting studs unless I take them in and match them up. just went through this on my '79 F250 4x4 a month ago, book was wrong.
Your truck is a 4x4. Do the rotors not just slide onto the hub over the studs which press in from the back of the hub itself ... like is the rotor not just sandwiched between the hub face and the truck wheel? Unless you are replacing hub too, the rotors should just slide on. Once the 8 lugs are tight, the rotor ain't gonna move when you hit the brakes. Does the center hole of the rotor fit the hub center correctly and center the rotor on the hub? I think the 2wd truck's get a hub and rotor combination, but 4x4s have them separate as I recall. .
On the front of a 3/4 4wd, the rotor and hub are held together tightly BY the wheel studs. So NO the rotor does just not slip off /on like newer vehicles now days. You have to drive out the wheel studs to separate the rotor from the hub.
