Overheating hubs

[rockcrawler31]

Hi all

i've noticed that my hubs are getting pretty damned hot after driving. Like, don't want to touch them hot.

I've checked the bearing torque, and backed the bearing locknuts off a bit. No help.

All bearings are brand spankers, all new grease, front and rear diff housings and hubs were rebuilt as part of the build up of the car. All new brake pads all round and brakes have been bled.

The brakes don't appear to be grabbing, and it's on all four corners that it's happening.

The rims are standard cruiser offset on normal 32 inch tyres.

Got me buggered. Any ideas what could be causing it?

is it worth pulling the bearings out and repacking them?
sounds like bearings to me but if there not too tight it may be a lubrication prob????
have you been through mud/ water since doing them?

i havn't done any real mud or water driving, and it started happening from the get go. I'm going to repack the bearings and try that but after that i'll be stumped.

I've lifted the front wheels off the ground and if you spin them by hand they don't keep spinning, but they're not exactly stiff either. It's hard to tell with the rear because you're turning the diff centre with the wheel.

had this issue on my 75 series...
One was a shot wheel bearing and the other time it was my hand brake pads rubbing inside the disc...minor ajustment.
sounds like yours is overtight on the wheel bearings...I believe you adjust them when fitting then go for a spin and backem off a little. best to have a tad amount of play than none.
Good luck

they do get warm, but your not feeling them after being in the brakes for a while, as this will heat up the hub heaps. i'd say over tight.

thanks for your input guys. I'll probably fiddle about with the torque settings for a bit and see how it goes.

You do have proper high temp bearing grease in there? The improper stuff melts and gets thrown out, then the bearings start to run dry, then hot, then eventually fail..

yep. HTB all round

Its most probably brakes dragging...jack each wheel up and turn....check resistance....if you went 100 series pads, they are sometimes too think....if you went 80 booster/master, it needs to be set up with proper pushrod lengths...can u push pistons back into calliper if ou remove pad and put wood in there
