I have a 2001 f150 supercrew XLT. I had a rear axel leak so I decided to change seals myself. Whan I was dissasembling the rearend I had to remove a "s" clip that seems to apply pressure between the axels. It was pretty hard to remove but now I cannot put it back in. I need to know the order in wich to assemble this. I tried installing clip before spider gears but I could not install spider gears after. I tried after the spiders were installed but can't seem to make the clip fit in. Please help!
