Re: Wheel bearings
I will only believe the torque settings on wheel bearings that are new
with new hubs and spindles.
On a repack, I don't use a torque wrench, I go by the bearing 'feel'.
When I can feel the bearings grab or rumble, I back it off, spin the
tire again and tighten some more. I keep doing this until the nut won't
suck in any more and the same backing off and tire spin stops the nut at
the same place.
Then I back it off and add the washer and lock nut. I usually get at
least an extra half turn after the first grab of the bearings.
Maybe my Haynes figures 50 lb will seat them and yours figures 80 and
the different backing off makes sense, but either way one seating never
works for me on a repack, I usually need 4 or more to get them nice and
snug.
I tried using a torque wrench and doing it 'by the book' once on my CJ7
and the wheel was flopping around after 2 weeks.

Re: Wheel bearings
That's my problem then. I used my torque wrench with new bearings on old
spindles. I can crank them down and back them off until I get them seated,
then crank them down one more time and back off until they sound good, even
if this isn't the 80 lb spec. I actually put the tire on with a couple of
lug nuts so I can turn the hub and load the bearing at the same time. I am
certain that I am mashing them in to the 80 lb click on my wrench.
On second thought, do we care that the spindles and or hubs are new or old?
The inside of the bearing race is not supposed to spin on the spindle, the
bearings roll around on the races, and these are new everytime. All we are
torquing is the preload on the bearings themselves, the condition of the
hubs and spindles is not all that critical, is it? Of course the condition
is important, but not from the perspective of the spindle nut pre load on
the bearings.

Re: Wheel bearings
That's my problem then. I used my torque wrench with new bearings on old
spindles. I can crank them down and back them off until I get them seated,
then crank them down one more time and back off until they sound good, even
if this isn't the 80 lb spec. I actually put the tire on with a couple of
lug nuts so I can turn the hub and load the bearing at the same time. I am
certain that I am mashing them in to the 80 lb click on my wrench.
On second thought, do we care that the spindles and or hubs are new or old?
The inside of the bearing race is not supposed to spin on the spindle, the
bearings roll around on the races, and these are new everytime. All we are
torquing is the preload on the bearings themselves, the condition of the
hubs and spindles is not all that critical, is it? Of course the condition
is important, but not from the perspective of the spindle nut pre load on
the bearings.
