I bought a 489 case at Carlisle a few years back with 323 sure grip. Turns out the pinion seal leaks. Was going to change the seal without replacing crush sleeve by measuring rotational torque before disassembly and putting back to the same spec. Using a beam type inch pound wrench I was only getting about 4 inch pounds and that is with the axles in (drums off). Now I'm feeling like it needs to come apart. Looking for any advice I can get with this issue, if it is an issue.
