So I just picked up a 1983 4x4 pickup and a day later the tranny started making bad noises. Long story short I am going to buy a rebuilt one from Marlin but have heard the L52 that came stock in my truck has issues with the input shaft bearing. I am not planning on doing anything too crazy with the truck but if I am going to drop the money for a tranny I don't want to have to do it again anytime soon. So I am wondering if their standard rebuilt unit fixes the bearing problem or if paying the extra bucks for the heavy duty one would be better. I know most people will probably say to just swap it for a tranny out of a newer truck but I am hoping to avoid extensive modifications on this truck.
