|  Help! What size wrench for spindle / bearing nut?
I have a wheel bearing that's about ready to fall off and need to buy a wrench on my way home from work so I can fix it over the weekend. What size do I need? I seem to recall something like a 24mm working on my 40, but its been a while since I had to one apart. 
(Just for clarification this is referring to the two large nuts that press the wheel bearings.)
Related question, what do you usually torque those guys at?
Thanks!
Shane

and you need a socket, not a wrench...

| I crank the inner nut to ~50 pounds in several increments, spinning the hub in between, to set the bearings. Then I loosen it and set the preload between 6 and 12 pounds, install the locking ring, and tighten the locknut to around 50 IIRC (someone please chime in on that locknut torque, as I'm not positive). Verify the preload and that should do it.

| From FAQ
You adjust the pre-load using the 54mm socket. Torque the adjusting nut to 43 ft-lbs
turn the hub right two or three times. Torque the adjusting nut to 43 ft-lbs again.
Loosen the nut until the hub can be turned by hand.
Torque nut to 48 in lbf (Yes thats inch pounds) and make sure there is no play.
Using a spring tension gage (Fish scale) measure the pre-load. s/b between 6.4-12.6lbf. Adjust as required. You do this by hooking one end of the scale to the hub and seeing how much it takes to move the hub.
Install Lock washer and lock nut. Torque the lock nut to 47 ft-lbs.
Check that the axle hub turns smoothly and the bearing has no play.
FSM says to check pre-load again with scale

| Once I've done the preload setting (tighten, loosen, tighten, loosen etc.) I torque the inner down to 5 ft. lbs. and re-check the preload (its always been within spec). Then tighten the outer to 50 ft. lbs. bend the tabs on the lock washer and I'm done. | |
