Ok sas done in a friends truck.Front Has a vibration bad when in 4x4, almost same when just hubs locked no 4x4, hubs unlocked in 4x , no nothing. New gears in front housing, new drive shaft, new Longfields 30s, new hubs. We took axle apart to find small amount of rubbing in ball, clearances it more (by a lot). Stumped/ missing something. I've built 12 front axles and 12+ sas.
