just play along with it if u have time tell him u are following his instructions whilst doing nowt may be browsing hmvf ! and make it your mission to wind up a indian chap!!:cool2:
my mk1/2 ferret has a alternator fitted plus front hatch modified to accept night vision scope far as i know last base over haul done in 83, last regiment if served with life guards ,who took it out to the gulf for a while!
as long as u do not feel a drive shaft vibration all is fine a prop shaft as u know will be balanced on its own ,not as a entire drive shaft assembly.worth using new nuts on assembly i found a few loose on my ferret and that was down to the military! if u think on reassembly u have a problem u could use a dti and measure run out on shaft and try moving flange faces relative to each other (bit overkill though!) if wheel hubs not lined up use opportunity to align them.
