I currently have most of the Rear Axle disassembled, cleaned, and inspecting parts in our '24 Couple for a rebuild. First, a special thank you to all who helped with advice on the removal.
I am one who starts to think ahead, so my question is,
How is it best to get the Rear Axle Assembly in the car? I See on page 154 Paragraph 625 in the Model T Ford SERVICE about a "rear axle installing truck", What is it and it is not mentioned it under removing the axle?
Look at the thread about removing the rear end - the things people suggest for that also work for assembly
When me and my friend, also name Tom, put the rear ends back in my'20 and then later the '15, we set the diff on a floor jack and while I was under the car guiding the drive shaft tube/universal up into the transmission he steadied it, and rotated a wheel as necessary so I could slip the uni into the receiver in the transmission. I "pre-positioned" the uni in the drive tube as best as it looked, had little tweaking to do. We then jacked the axle up to the perches and bolted things up. Whole thing took all of 15 minutes, maybe a bit longer bolting up the perches.
I used a heavy duty cargo ratchet strap to compress the spring when installing my rear end. Put 2X4 pieces under the spring ends and it went pretty easy.
Don't forget to drill and tap for a small drain hole before you put it all together and then think about it like I did...
