Wheel hub temp

So I just got done putting everything back after repacking wheel bearings. Took it for a short spin, came back and the grease caps are HOT,! Temp gun says 160 on one side.

My torque wrench is shot, so when I tightened I just did them nice and tight, (still able to turn). And then backed off one hole.

Is there a better way to do these without a working torque wrench!?

They spun, but not free cause the brakes drag...

Your wheel bearings could be hot because you did not set up the pre-load correctly.It is always a good idea to setup the front wheel bearing pre-load before the caliper/pads are re-installed. That way there is no external drag on the rotor and the rotor can be spun freely to evaluate the bearings. I would remove your pads/calipers and re-set your bearing pre-load using the factory procedure (you didnt). Beg/borrow a torque wrench and follow the procedure. You do not want to eff with your front wheel bearings.

Your wheel bearing caps could also be hot because your rotors got hot because your calipers are not completely releasing. That is a different issue.

Are they hot on both sides?

No rotors. Front drums. They are adjusted just so they begin to rub..
I will try to do hubs with brakes backed off tomorrow, and then set brakes. And get a torque wrench...

On 68 you torque the nut to 17-25 ft-lbs while turning the drum/rotor/wheel/tire. Then you back off 1/2 turn then re-torque to 10-15 in-lbs. Not sure if earlier uses a different sequence.

Backed off one hole?
You mean backed off one slot I'm guessing. Might be pretty close.
The issue is how tight you cranked on it to begin with. My guess is
too tightly....
As suggested, use a torque wrench to set pre-load on bearings.
I work for a bearing manufacturer and teach the proper procedure.
I don't even do it by feel.
It doesn't take much effort to be too tight and kill the bearing.

Just a drive around a couple of blocks at low speeds can make brakes too hot to touch for a few minutes upon return. That heat will also be present at the hubs. Multiple personal experiences.
