OT:Nissan navara centre bearing and pinion seal.

[mattyb]

ok guys i know this is a bimmer site n all but my neighbour has asked me to help him out cause he knows im partly capable with most things mechanical and hes a bit short on reddies at the mo. 2000 nissan navara 4x4- rear pinion seal shot and upon closer inspection centre bearing looks a bit stuffed as well. doesnt look too hard but is there any knowledge out there or little bits of brilliant and trade tricks that i might need to know. ive searched 4x4 forums and the like for this vehicle but there doesnt seem to be the same depth of forum brilliance that we have here. thanx in advance for any help or advice.
ps. ive just done mine so i am aware of lining things up proper and the preload on the centre bearing
