My very last question/problem with this damn disc conversion is with the wheel studs. The reccomended rotors require a larger diameter stud than both the old drums and the hub. This leaves the rotor kind of "floating". First it was hard to get the rotor centered on the hub. I fixed that by installing 4 of the larger diameter studs to ceter the rotor then installing 4 normal studs then removed larger studs and installed remaining normal studs. This has gotten the rotor almost centered leaving it with about 1mm of runout. I could not find a stud that fit the rotor and hub and was long ebnough. I wonder wether the friction of the studs will be enough to hold the rotor in place during hard breaking. I am curious if anyone else had this problem and how they overcame it. I know a lot of small 2wd cars use floating rotors but I feel like this is halfassed.

Some 4x4s use the floating, or top hat style rotor (Cherokee, S-10, 1/2 ton GM). One thing you can do is drill two smal holes through the rotor and the hub flange. tap the holes in the flange and bolt the rotors on. Depending on your type of wheel, they might have to be countersink bolts. But, I'm sure you can figure that part out.

If I cant find a stud that work I may have to do that. I hope I have some good bits :D . Anybody find studs that will work?

charlo, are you doing this on a 60? if so this is good info for me too becuase I plan to do this same swap in the very near future, thanks.

What kind of axles is it?

My mistake this is a 14ff. This is the approximate kit that shaker sells. I dont know if there are minor differences, I dont believe so. I dont know what studs the D60 uses but this could be an issue with the 60 conversion also.

Hmm....I just built a 14 bolt with disks for a buddy, the rotors mit nicely on the hub and the studs fit snugly before I pounded them through, no slop at all. Are you sure you've got the right rotors? I just used '78 Chevy truck 3/4 ton rotors. I'd take them back and get another pair, sometimes you get some funky ones. I once got one that had like five balance clips in the vents all on one side, no way am I going to run that junk, I grabbed a different rotor off the shelf and it only had one clip, cool, that's what I used. I don't know why that other rotor ever even made it into the box, it should have been tossed in the reject pile if it was that out of true.

I am starting to think I have some unusual 14FF. The braket spacing was off by about 1mm, and I seem to have different hubs, drums, and studs than everyone else. Stupid military axles. I bet if I drill out the hub I can use the larger diameter studs. Any reasons why I shouldnt do this?


Charlo

nope

Ok so I am now using the studs from the newer 14ff and they seem to work well. They are about 1/4 inch shorter than I would like but will do the job just fine. Rotor spins nice and true. I cant believe I am the only one who had this problem. Thanks a lot for the help guys.

Now does your truck have the 3 speed th350......
or the "4" speed th400??????:rolleyes: :rolleyes: :rolleyes:

If I was a ford guy I would have believed it. FURD is :rainbow: :flipoff2: :flipoff2: :flipoff2: :flipoff2: .

I cant believe you tracked me down in an old dead post of mine LOL! :flipoff2:
