hello all,

I have a 94 Patrol, TD42, running on 285/75r16 tyres. Noticed when I was trying disengage my hubs after a tackling a track, it was almost impossible to try to hold and turn to disengage the hubs.

To try to resolve the problem I recently had my front hubs and bearings completely serviced. In addition new front rotors and all four corners have been serviced at the same time. It didn't help.

If I was to go for a drive out to the sticks, straight road, no traffic etc the hubs get warm which I believe is within normal operating temperatures. However, if I were using my breaks eg. general start/stop, up and down tracks or even hilly windy roads the hubs get too hot to touch. Today I took the Patrol for a short drive to a local hilly area and then went to a mates' shop to have the temperature read. It was 79.9 degrees Celsius on both front hubs.

Does anyone have any idea what would cause this and how to resolve this? I also read somewhere running bigger tyres may be a possible cause. is this normal for a GQ? What should the standard operating temperature be?
