I was told I may have to cut down the axle if I get it. Any thoughts on whether it will fit, what I will need to do to it and is this a good price? And how do I tell what front axle I have for sure?
Right now I have a 9" out of a '78 Bronco I am going to narrow for my CJ6 to wide track width. Looks like I will have to narrow it about 10" total. Also have the front high pinion Dana 44 but, am going to use a Dana 44 axle out of a '77 Wagoneer, only have to cut 4" out of the drivers side tube and move the spring mount.
Trouble with the Bronco front axle is in 1978 Ford went to a large casting on the inner-C that is not able to be readily cut down, unless you are going to retain the Ford radius arms. '77 and earlier Ford Dana 44 front axles had the mounts for the radius arms welded onto the tube and can be removed to narrow and convert to leaf spring suspension. Also the Ford front axles have the pumpkin on the drivers side, CJs have the pumpkin on the passenger side unless you are going to also swap the transfer case!
Another nice thing about the '77 Wagoneer axle is it is factory spring under axle and has the mounting pad already on the center casting in the right location for the swap. After pulling the axle out of the donor I figured out 2 more advantages to the Wagoneer axle, it has flat top steering knuckles that if I ever want to run high steer it is ready, and the tie rods are also mounted on the TOP of the steering arms. So I don't have to do a tie rod end flip.
