Hi all, I stumbled across this site while researching combining two axels to center an FJ60 diff... apparently it has been done, so my question is that I have not been finding is how much does this affect the wms-wms width? I have a FJ60 front that I would like to match in width, or come very close.... for minitruck axels that I currently have to use with the FJ60 rear, are an 84(55") and an 86(58") I have not taken any measurements yet, seeing if anyone knows first before I start cutting.

Its not clear what you are asking....
You would fabricate the custom width housing as needed to work with the mini truck axle shafts that you chose to use in order to get the width you want. Cut the outters off the mini truck housing and graft onto the cut ends of the FJ60 housing. Grossly oversimplifying the process, but that is all you're doing. The axle shafts you elect to use control the WMS.

Asking which axel shafts are likely to get me to where I want to be, the '84 or the '86, to match the width of the FJ60 front. Sorry I wasn't clear, but you seemed to understand what I want to do.

FJ60/62 front axle WMS width is about 58.5". There are wide ranges of reports on the internet, but that seems to be the consensus here:
Tech Debate- WMS width of FJ6X front axle
from ih8mud FAQS: fj60/62 front axle wms to wms = 60" from Cruiser Outfitters: fj60=58.5" fj62=60" from other web forums(Marlin, Yotatech, Pirate) fj60=58.5" From one mud member posting in a hardcore thread-based upon an actual measurement: fj62 front wms to wms=60" from another mud member...

Sounds like you should use the 86 rear axle shafts if you want to match track widths front & rear.

I centered a 40's rear using parts from a mini truck. I cut the ends off the 40 axle just behind the outer wheel bearing. The mini truck is the same width as a 40 and the axle tubes are smaller. I then cut the minis housing just b4 it gets fatter for the the 3rd, the tubes will eventually be trimmed for proper width. Slide the mini's axle tubes with the mini axles installed into the 40 housing. You want the mini axles to engage the 40's 3rd member side gears properly. Both sides of the tubes will probably have to trimmed to the proper length. I drilled holes in the 40s housing for rosette welds and welded the ends too. Make sure the axles slide in and out easily and things are centered. This mod also eliminates the C clips. I've heard you can do the same process with the 60 housing and using a Tacoma rear end. They are supposed to be the same width. You have to search to confirm this.

I have done this many times. For a bit more width you can use 1st gen tundra axles instead of IFS rear axles. Everything else from the above mentioned tech article will work. I usually laminate the smaller diameter housing with the leftover pieces from the cruiser rear end to make the housing the same size throughout the length. I also usually add a rear truss for overall strength as well.
