wheel bearing socket for M101A2 trailer

[jimm1009]

Can anyone tell what size the nut is for the wheel bearing used on the M101A2 axle with the 8-bolt hubs that use OEM Chevy wheels?
Or possibly the part number is they use a particular brand like OTC?

I do have the TM but it does not describe wrench size.

Thanks,

Thanks Tim but don't go to that trouble.
When it arrives tomorrow I'll check it out.
I was just looking for some info in advance to order the right one
if I don't have it.
I purchased one for my middle son to pull behind his truck.

PS: How do you put a torque wrench on those blue handels to set the correct preload on the bearings?

You have to do it by feel.

Ditto on the doing it by feel.Never have used a torque wrench on wheel bearings.Just snug em up then give it a spin and then depending back it off a smidge.I even think that was how it was explained way back when in auto shop.

When I rebuilt my hubs, I believe I used either a 1-1/2 or a 1-3/8" socket. I had both on hand, there was a little slop, but not enough to round anything out.

I did use the torque wrench to set the bearing into place (30 ft-lbs), then backed it off a smidge before putting in the cotter pin.

i used a pair of vice grips to remove mine.......it should only be snug fit with no side play........

M101A3/M116A3 uses 1-1/2" socket. Craftsman is about $6.00 if you can find them in the store.

You will never hear of a bearing burning up from being on the loose side. But too much, and watch out! Snug enough is what mine get!

Same as I was taught.
Spin the hub,
Tighten until it stops spinning,
Back off the nut to the first cotter pin hole,
castle retainer and cotter pin in
spin the hub if it rolls smooth
Bend the cotter pin legs back
You are good to go.
