Just got a this 95 sierra truck with only 45k miles. I just wanted to know if there is any common problems with transmission or engine that i should know of? my grandfather passed this down, i know he maintain the maintinence on the truck and regeared the differential for towing advantages. So i guess the next question what should i do with the differential now? I have no intrest in pulling my trailer with it just because i have my diesal truck. This is going to be my desert ride/mini toy, and tips or advice helps and is appreciated thank you
