Just wanting to double check on the torque settings for the front bearings.
On the old 80 series the first nut (nearest the thick washer) was not very tight (48 in pounds if I recall correctly) but the manual for this one says 48 ft pounds. The second nut (on the outside of the tabbed washer) has the same torque number as the 80 had. So I'm concerned that the new manual (Ellerys) has a typo. Could someone with a genuine Toyota manual please check and let me know?
Thanks from the Moose

as a mechanic wheel bearing nuts are done up by feel.
Do nut up tight,
then back it off,
then take it up till just feel contact with the bearing.
fit lock tad
do second nut up tight
bend lock tab over

Thanks Graham
That's sort of the way I've always done it in the past and will continue to. I've always done up that inside nut by hand - given I'm not a big bloke I figure it can't be too tight that way. Then the outside one to the torque stated.

I have no intention of beginning a bearing preload argument here.
My Hilux manual says:-
For 2wd tighten to 16Nm. While turning hub in forward direction tighten to 27Nm to
seat bearings. Loosen quarter turn and tighten by hand till snug.
For 4wd tighten to 58Nm while spinning hub. Back nut off and tighten to 24Nm while rotating hub. Verify rotates smoothly and no end play. Install lockplate and nut and tighten to 47Nm. Bend tabs.
