April 24th, 2013, 16:55
SO... I ran into a snag. I have the C-8.25 on my 97 XJ. I have 4.56 gears in it. I am installing the Spartan Locker in it. My problem is, My ring gear, since it is now 4.56, is really thick!!! I cannot remove/install the center pin without removing the Ring gear. With the Locker in, I cannot get the c-clips in since the center pin had to be installed before the ring gear. I NEED HELP with any ideas on how anybody got through this problem. Thank you in advance for any and all help!

You have to grind a little bit off the teeth, I only had to clearence 2 teeth to get the cross pin in.

^ What he said. You have to try to position the ring gear on the carrier so that you only have to grind one tooth but sometimes you can't avoid grinding 2 teeth. You don't have to take very much off, just enough to allow the pin to slide past.
