166 degree warn hubs

[RangerRough]

hello community!

I checked the temperature of my new hubs when i was out today crawling around in a mixture of 4 low/high and my hubs were hot to the touch, so one side was 161 and the other was 166 degrees. I am running a 96 ranger 4x4 4.0 on 35's with the warn jeep hub swap. what is the normal temps on these hubs? I also checked the 2 axle/bearing retaining nuts, first one finger tight then the spacer/locker, and the second nut as tight as i could get it, i watched to make sure the first nut never spun when cranking down on the other. I also put a new bearing in the driver side packed with grease but i did not replace the race.... any ideas why they are so hot?

What was the outside temperature while you were out wheeling?

~160 degrees sounds fine to me, especially with what I'm assuming is probably 80-100 degree heat outdoors?

Your bearing locknut adjustment is not good, by the way. "Finger tight" is way too loose, especially with a new bearing. Follow the service manual process to a T for new bearings... used bearings, I tighten to snug with a ratchet and then back off 1/8 to 1/4 turn, spin the rotor, should get a small amount of resistance and zero lateral play

Thirdly, keep in mind that cheap parts store bearings and races are often a hair out of spec and a new bearing with a worn race is not a good combo. A new PAIR of SKF or Timken bearings and races is what's really needed to do it right.

And the bearings that come in new rotors are not top shelf stuff.

I put new Bendix rotors in my truck, all four races were crude Chinese junk... that were promptly used as drivers to drive in new Timkin bearing sets.
