While apart, think about what else you need to do.
Pull the drive saft, lube the WHOLE rear end. You'll also need to keep in mind that this is a 10K maintenance while you have the CT on.
Also read up and decide if you want to do the bearing mod. Changing out the single roller bearing on the LH side, to the same double roller on the RH side. Do a search and read what people say.
The WHOLE rear end includes pulling the drive shaft out of the pinion cup and cleaning both. There are two holes at the bottom of the pinion cup that are half hidden by the flange nut that holds the cup on. Use a pick to thoroughly clean these as well.
