At five degrees caster there's only one degree on the pinion. You're right, with the hubs there's no issue with driveline vibration on the street. However, under certain amounts of flex or driver side camber the driveshaft hits the trans pan. Only way to correct that is to reduce caster. Having a corrected housing allows good caster, and raises the pinion enough that the driveshaft will clear the trans. The housing is in good shape. with Pro Steers, sleeves & gussets. Can probably be turned at a decent price, which will help reduce the overall cost of the PR44. If I wait until it's broken or bent, it's scrap.
I'll run the PR44 with the Spyntecs and may use slugs when in Moab, etc.
