5 lug front rotor conversion...need help
I finially got around to pulling off one of my 4 lug rotors today. The fist thing I noticed is that the 5 lug Ranger rotors are almost 1/4" wider, as I had been told earlier. After doing a mock up I determined that just about 1/8" would need to be shaved off the inside of each caliper, both at the top and bottom. As it is now, the rotor would turn freely but does scrape slightly. I next compared the bearings. If you use the origional spindles on the Mustang or T-Bird, you will have to use the inner bearing for your car. The inside diameter of the Ranger inner bearing has too small of an inner diameter to fit over your spindle. Heres the problem, I read on the "Coolcats" sight that you need to use the Ranger's race with your inner bearing. I dont think that this will really work. The two just dont match up that well. When I dropped my inner bearing into the Rangers race, it does not fully seat. In fact it sticks up almost 1/8" higher than it does in its own origional seat. That cant be good. I checked out the grease pattern that it made on the race and verified, that the rollers are sitting up just too high in the seat. I next wondered what would happen if I used the bearing and race assembly from my car and press it into the Ranger rotor. That will not work at all. It turns out that the outside diameter of my inner race is a too big to fit in the Rangers rotor. I believe that it will work to use my outer bearing and race assembly, on the outer side of the Ranger's rotor. I am just not very comfortable with using the inner bearing from my car with the Ranger's race, if it not going to seat all the way. I think this would result in extra heat and premature bearing wearout or failure. I'm going to continue to research this, but wonder if some of you have used this combination and if so have you observed any problems?
