As a newbie for a running and setup up a 9" floater, I have dumb question (coming from a pollack). I have installed my axles into the housing, but noticed that they will go approx. 1/2" into the drive hubs on each side. Is this a problem? Are the axles suppose to float inside the hubs and spool? There is a threaded hole in each end. Are there suppose to be bolts, etc., in them to govern the distance from the outer cap? And lastly, how do you determine the correct axle length for a floater rearend? Any pertinent information will be greatly appreciated. Thanx.

This sounds like you have a full spool axles that work with a mini spool are just a little shorter cause of the cross pin in the mini spool if this is the case put a bolt in to the end of each axle so the head of the bolts take up the slack where the cross pin would be and it will hold the axles out into the axles flange with a aluminum drive plate I would want all the spline contact you can get .hope this helps Good luck

I got aluminum buttons with my axles that were inserted in the axle ends (toward the spool) and were used to fine tune the float. One side was perfect the other needed about 1/8 taken off. The bolt should work too.

Thanks guys for the feedback. I do have a full spool setup in my chunk. Do you really need to space the axles out, or can they just sit in there and float? I did not notice a bolt hole in the spool end of the axles for spacing the axles outward. I have plenty of spline contact in both drive hubs, and I'm sure it's the same with the spool. Just trying to get an understanding of the setup. Oh, to ask again, how do you determine the required lengths of axles? I'm asking for a buddy of mine that is fabricating his own floater with wide 5 hubs. Thanx.

You have to get something in the center to space them out. I have never seen a set of floater axles that do not have the hole for the center bolt. If you have 1/2" on both sides and you do not put a spacer in the middle both axles will slide to the right in the corners and you will have very little engagement of your left drive plate. When you set the spacing you can leave a little slack because you don't want the caps pressing hard against the axles, but I'm talking roughly 1/8" total.

Also if you dont space them they will move around and wear the splines as they slide back and forth. USe a bolt in the end of one or both axles so that you have no more than 1/8" total free play left.

Thanks for the info. Going to pull the axles out tonight and get them adjusted with the bolts as you're advising. Thanks again.
