Ok, I have installed a couple TTB's before, but never had this much trouble. I just put a 8'' skyjacker lift on, and doing a 2wd, to 4wd conversion(f-150, not bronco) When i went to put the drivers side axle under it just wouldn't go. I bolted the radius arm in, and left it loose for movement, but when i tried to get the axle pivot point into its bracket the thing would not go!! I jacked up on both sides seperately, and then at the same time, and no help. The thing isnt even close! Anyone have any suggestions out there? I need to get the axle under there asap!
