Hello everyone,

I know this has most likely been beaten to death, but I need to replace the rear shaft oil seal. I am one of the lucky ones that has a transfer case that gets hot. I am planning to drain the case and replace the oil with 75-140 weight synthetic oil. And I hive seen a bunch of threads with numbers listed for the oil seal. But is there one of the oil seals that does better with high heats?

Thanks
