Pinion seal replacment for a 66 Corvette

Can anyone tell me if i can relace the seal on the pinion shaft and stay out of trouble. the side shafts are not leaking.
Are there critical items that I may need special tools for, noting the independent rear suspention etc?

I assume taht I remove drive shaft unblot the yoke remove yoke remove seal and replace all. Do I need to tork the yoke, does it have a "crush spacer"?

It does have a crush spacer. When you put the yoke back on you must be careful not to over tighten the nut and increase the pinion bearing preload. Many people will tell you to mark the nut and count the number of threads showing. Then tighten the nut back to the same place. That will work pretty good as long as the seal is all that you are going to replace, but if you replace anything else then that method will NOT work.

Here is my method. Remove the nut and yoke. Remove the seal and clean the housing where the seal goes. Smear a thin film of RTV sealant in the housing where the seal goes to seal up any scratches in the housing. Drive in the new seal. Smear grease on the rubber lip of the seal. Clean the splines in the yoke and smear RTV sealant into the splines so that oil will not seap out through the splines (it will if you don't seal them). Do NOT put sealant on the splines of the pinion shaft. If you do you will push it right into the outer pinion bearing. It's best to use a new nut, but you can use the old one if you need to. Be sure to use red Locktite on the threads before you put the nut on. Torque the nut to 150 foot pounds. I've tested this before and it takes about 175 to 200 foot pounds of torque to increase the preload on the pinion bearings, so 150 should be enough to hold everything in place but not increase the bearing preload.
