I'd sure like to avoid the ~3 bills that will set me back .. Online threads refer to the locating mandrel shaft with the locating bushings on each end to locate the housing pieces before welding them & talk about out of round in thousands. If I get the end flanges parallel wouldn't I be OK? Your thoughts please. thank you for your time. live every 24 hour block of time like it's your last day on earth

You need a 3rd member to hold some machined pucks to fit in the bearing caps and some machined pucks to fit in the housing ends (I would use big Ford ends)and a dead straight shaft to fit through all four pucks. Cut the housing to length, assemble the parts holding it all together with worm gear hose clamps and weld in small steps going from one end to the other to avoid warping the housing. And shazaam you have a welded narrowed housing and the tool to do it for your friends. 1986 Dodge Ramcharger 440 2wd, Bracket Racer Under Construction 1998 Ram 2500 QuadCab, new daily driver. 2008 Honda Element 2014 Carry-On 7x14 Cargo Trailer

All three together to locate the ends for tack welding. Sound Ok so far? Getting the right dia pucks is the only part that'll take some effort. live every 24 hour block of time like it's your last day on earth

I used the early "green" bearings on the axles that allow for a lot of misalignment. I made two trips from Seattle to Reno and back and it rested in the garage a lot. The last time I drove it, the right axle bearing was talking to me. I have learned that perfect alignment is the answer to a lot of problems. Use a jig, you will be glad you did. 1986 Dodge Ramcharger 440 2wd, Bracket Racer Under Construction 1998 Ram 2500 QuadCab, new daily driver. 2008 Honda Element 2014 Carry-On 7x14 Cargo Trailer

To keep you OT, I'll send a PM since you asked, but first, at least read the first paragraph of my signature link on bias.
