Took it to a transmission/diff shop. They managed to fix the two speed vacuum shift, but said they couldn't identify a replacement for the differential pinion seal.
He said if we are replacing the differential pinion seal it may make sense to replace the pinion flange as well.
So how can I find replacements? I've went to napa and my better parts store, monument, and none of their books cover the 2 ton. They can usually find the ones for the 1/2 tons.
Any help is appreciated.
