My rear differential housing is leaking around the seal. How hard are the seals to change out?

 

its a pretty long job, here is a decent writeup

torque the pinion nut to spec, dont go by feel. and as said in the write up those nuts arent meant to be re-used and sometimes walk off, give it some blue loc-tite and call it good.

dont let kyle scare you, it's not a long job at all

 

well maybe not for you it would be but for myself it would be a longer job because i would run into some sort of problem and/or have something brake on me
