Axles that can be swapped in place of the stock axles
If you have been paying attention JP recently upgraded the axles under their project M715. They used a '85-'96 Ford dual rear wheel highpinion D-60 front axle and it is a direct spring-over bolt in for our trucks. Measuring at 77" + or - it works well with surplus Humvee wheels on M trucks. They also used a D-70 rear from a Chebby dually (not cab and chassis) truck that measures 73" wide.
The problem with this rear is that you still have to move the spring perches. I have found a better solution. A Chebby G30-G.M.C.G3500 van with dual rear wheels features a 73 1/2" wide D-70 and more importantly SHARES THE EXACT SPRING PERCH WIDTH AS OUR TRUCKS!!!!! It is a bolt in and as an added benefit is wide enough to allow use of the chevy drums with their parking brake system.
Put one under my truck this afternoon and reused all the van stuff like u-bolts and anchor plates. One shock mount must be moved as the van shocks are staggered(one in front of the axle and one behind) and the factory jeep rear brake line needs to be lengthened because the van flex hose is on the passenger side. Simple swap.
Jp used 14bolt GM hubs to widen their rear out to match the front axle. This works great if you want to run discs on the rear, however the rear disc parking brakes sucked when new and installed on a passenger car. I doubt they would hold a Kaiser with big tires. I plan to leave my truck drum rear and run 1 1/2" spacers to get my width right.
1982 Van rear the right One?
I have a 1982 GM Beauville that is a one ton what rear is this? 14 bolt? it is in the weeds so I haven't crawled under it yet.......the glovebox says 4.10 rear could it also be limited slip? If this will bolt in I am in luck cause the ford Dana 60 I have is also 4.10
Traded axles out of an old project for Dana 70's from a W300 field operating room
I did, I probably sholdnt have but I did. Got a call from a kid needing and Dana 60 with a Detroit and Dana 44 front with limited slip and 3.73s. Said he heard that I had a set. I said yep who ya been talking too? lol We have a mutual friend ( yes I do have some friends lol ) who told him of my old M715 frame I had under a J 4000. He wanted these for his J 2000 cab with a 6.2 diesel and M37 bed he up on a Grand Wagoneer frame.
He traded me from and Rear Dana 70's out of a W 300 field hopital operanint room. 1/12" 35 spline, input torque rated at 8000 lbs!! Even I would have a hard time breaking these axles ( famous last words ).
To make it move Im goint to 350/465/NP205 with a Hydraboots I bought out of a 87 Cheby one tom. 5 gal can in the cab so I can get it to move to work one the beast. Pushed the 5900 lbs into a space and that is all I ever want to push it again. Eventually Ill drop in the 2nd gen 6BT Cummins married up to a FSO 6406a or 8406a and divorce a SCS gear transfer case.
In the mean time I was wondering if I want move the spring perches and fog on or 4 line both axels?
Ideas and suggestions welcome!! Ill try to add pics but have to unfubar the back of the computer where the 14 month old got ahold of the wires!! OR email me and I can send them directly to you. ( depending on how the unfubar project goes )
