I installed a dana 44 rear axle that came out of a 87 lorado in to my 87 pioneer. Now my rear drive line is to long. I have a 3 inch lift and in the rear they use blocks. I know that they are on there locating pins. I also put some newer leaf spings in out of a 88 but did not see anything different there other than they where not as sagging as mine where. What went wrong?
