Hi guys Im about to shorten my axle but dont know how to meauser so it will be right does any of you guys know where to find info or some pictures of how to make the meauserment right

Hi Im using a spool

I'm in the process of doing the same thing but I'm switching to a posi instead of a spool, also switching from a 8 3/4 to a Dana 60 with a posi. I originally installed the axles one at a time in the 8 3/4 rear end bare housing and measured how far they stuck past the center of the housing. The axles are Strange Engineering race axles with 35 spline splines ordered for a A body with a stock width housing, I ended shorting the housing one inch per side and had to see how much I needed to cut off, I added(removed) an additional 1/4 inch per side to what was center to allow room for heat expansion because it is a street car. You can also install one axle at a time and measure thru the axle housing from the other side axle baering end and write it down, do the other side also and add the two together and mmeasure the end to end from both bearing flanges and see how much you need to cut off to make them equal and cut an additional 1/4 to 1 inch off . Most spools have a space between the splines in the center where there are no splines so the axle can stick into that area and have no contact with the spool splines, I would allow at least a 1/4 inch between the end of the axles in that area Don't forget to have the break backing plate or whatever fits between the axle and the housing ends for the brakes I hope this helps

thanks for your help I find a guy who told me how to meauser so it will be right infact it was very easy when I think about it
