Wondering what is involved in converting an 8-lug FF60 to a semi-floating with a more Jeep friendly 5 on 5.5 bolt pattern. The 60 measures 66" WMS-WMS, but needs to be more like 60", don't know if removing the spindles will fix this. Any issues with axles, brakes, or wheel bearings? Any help appreciated.

cut the tubes down to what size you need, weld on ford 9" outers, put in 35 spline detroit, order 35 spline axles for the 9" press fit and a rear disk kit. i know currie builds them along with alot of cheaper companies if you wanted some one else to do the work.

personally I would leave it full float. I think that it is a much stronger setup then semi-floats.

30 spline FF is stronger than 35 spline SF Nah, I dont think so. Besides he needs to narrow it for his application.

I dont know 60's very well, but wouldn't/isn't there a way to make a 60 that is 35 spline and ff????? Isn't there a spindle out there that would fit that application?

You can either bore out the spindles, find a housing that will take the bigger axles, or put 14 bolt outers on a 60 housing and get 35 spline axles.

There is no doubt a FF is stronger than a Semi-floating axle, and I know that the 14 bolt spindles will alow for 35 spline axles, but I would realy like to end up with 5 on 5.5 bolt pattern. The only way to achieve this is to go Semi-float. What do I need to harvest to make this conversion? I would like to stay drum in the rear.
Thanks <IMG SRC="smilies/beer.gif" border="0">

You need the outer ends of any non c-clip axle such as the previously mention Ford 9in out of a 4X4 or a Chrysler 8 3/4 out of an early Dodge 4X4 or a Dodge Ford or Jeep Dana 44.
Another option would be to get a Dana44 full floater kit such as the one Warn sellsand use the hubs and drums from an early 70's dodge ford jeep or IH and keep it full floater for the extra strength.

Don't do all that work to a 60. Got get yourself a 60 rear out of a J10 Jeep Pickup. It is already a semi float, 35 spline setup that is offset. If you hack one side to match the other, you have a 60" semi float, 35 spline 60

Thanks Dimitri,
Cutting down one side of a J-10 60 seems like a piece-o-cake. Once cut down to 60" is the rear centered? Are the 35 spline axles the 1.5" ones that can be made to fit a ff60? How about the rear end from a J-20, is it also an off-set semi-float 60, or is it full float?

Wel I am pretty sure they are the 1.5" shafts. Onec you cut one side down, the rear IS centered. I am not sure about the J20, but I thikn they are the same.

Thanks, I will look for one this weekend and rip it apart, checking width, axle spline and diameter.
