How hot do your hubs get?

[CrnCnn]

So I got new rotors and pads from R1 and finally put them on a few months ago. While I was in there I repacked my bearings. It seems like my hubs are really hot when I get done driving now.

The problem is that I never really payed attention before.

Hot hubs usually indicate bearing problems. If you repacked a while ago they may just need adjusting. Check them first.

Do you still have your CVs out? I've never taken apart the front end of my VX before, so I don't know if it is the same as the 91 Trooper, but is there a hub nut in there? Did you possibly over tighten it? Other than lack of grease I can't imagine anything else causing too much friction.

No, everything is back in and normal, the only change other than rotors is the diff brackets. There is not a nut for the CV's, just for the hubs to remove the rotor. If I loosen the nut then the rotor seemed to have play.

I believe the load for the bearing adjustment is 5-5.5 lbs.

[CrnCnn]

well my hands arent really calibrated for 5lbs. Should I have gotten a tool? The hub nut just pretty much unscrewed when I tapped it with a flathead then spun right out so I didnt put it on too tight as far as I could tell. just tight enough to where there was no play in the rotor.

Too much grease can also cause a build up of heat in the hubs.
You need to pack the bearings well and have residual grease in the hub, but not have it packed tight with grease.

really?? hmmm cause I got 'em pretty full. I mean I was always taught to pack them til they are basically full

I measured the temperature on my hubs after having them repacked. I drove about 15 minutes ( my commute to work ) then took the temperature with a infrared thermal thingy. I did this for 3 days in a row , temperature read between 140 fahrenheit and 150 fahrenheit . It was summer time so ambient temps. were in the 90's. I haven't a clue if those temps are normal.

[CrnCnn]

It could be normal. They aren't glowing or anything. I just was sniffing out my new brakes and felt the hub cause I was there.

There is a write up on the site. They used a fish scale.

"Really hot"?

Brakes are dragging!

You're not doing a lot of heavy braking right before you check the temp are you? Brakes will easily put a lot of heat into the hub/wheel even if they're dragging just a little. Bearings - not so much - unless things are BAD wrong. You'd have to crank down on the bearing preload quite a bit - or have totally shot bearings - to get "really" hot - as in can't keep your hand on the wheel very long. Might want to jack a wheel off the tarmac and see how much brake drag you've got...

BTW the 4.4 - 5.5 lbs is for a new bearing and seal. For used bearing/new seal the preload is 2.6 - 4.0 lbs. And you don't even need a a fish scale - just find an object with the desired mass and hang it on a lug bolt at 3 o'clock. I use a gallon milk jug half full of water - hang it on the lug bolt with some wire and turn the preload down until the 4.15 lbs of water won't turn the hub then back off a hair and call it good. This way you don't have to have three hands - gravity takes care of the tension leaving you one hand free to spin and one to tighten...

dam now i am pi$$ i spent all that money on my snap on inch & foot pound torque wrenches

quite genius & great for the road side fix !!!
