8.8 swap

Had some serious issues with the Ratech solid spacer. long story short I put the spacer in with no shims and it was still too loose to get any pinion bearing preload. The oddiest part of it all: we threw in the old crush sleeve that was longer (.438in vs .420in) and was able to get a decent preload. For those that don't know, the thicker crush sleeve should have been even looser than the spacer. No idea what was going on there but I'm buying another one from Yukon and if that gives me trouble I'll use the damn crush sleeve.
