I have a 1979 c10 SPORT stepside.

So I have a strange vibration I have had since I have owned the truck, 25 years. Frame off restoration and it is still there. I had a leak on the front seal of the diff. Changed the seal. still leaks. Leads me to believe the pinion is bad. Thinking about replacing it. How hard is this. I have seen videos and what not but I am scared about getting that crush sleeve set right. Do I need to pull the axle to get the pinion out? Do I need to replace the ring as well? Anybody have a posi unit I can just throw in? I have a 12 bolt rearend.

I am scared. help a guy out..

Thanks
Chris
