It certainly doesn't hurt to re-check end-play, even if 'nothing
changed;' the DPO--including yourself--who last did them may not have
gotten them exactly correct, and even a slight bit of wear-in could
change the depth. End-play can/should be checked and adjusted dry or
with just a light oil on the bearings--grease gets messy and could be
contaminated in the process--then clean them thoroughly before packing
with grease and reinstalling.
I torqued my BJ8's bearings to 'spec' once, and one of the tabbed
lock-washers spun and made a noise like a bearing failing (until it
wedged itself against the shims). Now, I keep my torque wrench in the
drawer and torque to the last slot on the castellated nut that a
1/2-inch breaker bar and my 'armstrong' driver will allow. I don't think
there's much risk of overtorquing the nut--what is it, 3/4 inch?--and,
like a lot of aftermarket parts the tab on the inside of the washer may
not be a precise fit in the slot. I torque the nut until the hole in the
axle and a slot on the nut will /just/ fit a cotter, so the cotter will
resist any turning of the nut from the get-go; any gap could allow not
insignificant release of the nut's load.

The torque spec is 40-70 ft. lbs. The reason for that is to allow
you to get lined up with a hole in the axle for the cotter
(splitpin). If you did not change the bearings (just repacked
them) then there is no need to measure...replace the original
shims that were removed. IF you put in new bearings, then you
should measure the gap, as described in the workshop manual, and
adjust them as needed.

<div>Use Hi Temp wheel bearing grease to lube, especially if you
have disc brakes. Clean, check for wear (See article in Jan.
issue of AH Mag) and lightly lube the splines of the hub and
wheel either with the same grease or anti seize grease. Check
this flex brake hose while there, for cracks or bulging. Most
info from manual, rest from doing it...Hank<br>

No, you don't need to re-torque the nuts. They are torqued to
spec
on<br>
installation and the cotter pin inserted to keep them there.<br>

I changed the front bearings on my BJ8 about 500 miles ago. Do
I
need to<br>
re-torc the nuts at some time soon or let it go?<br>
