Hi all,
Ive got a 99 Patrol coil cab ST 4.2d and have recently notice the front free wheeling hubs run hot, but not all the time.Ive had new bearings put in and we have made sure they are not over tightend plenty of grease and no sighns of extreme heat when pulled down. This could be normal as i dont usually touch the hubs on a regular basis if you know what i mean.I just got knew tyres thats when i felt the hub.You cant leave your hand on them for to long thats how hot htey get.Its both sides can any one shed some light on this.There is no Brake drag and everything else looks allright, Do they run Hot sometimes??????.
Thanks guys in advance.

Quino.
If your load sensing valve on the rear axle is not calibrated corectly or has fallen of the full braking will be on the front brakes. just a posibility. Eric.

Mine do that too, was told you can actually use TOO much grease.

Will get round to servicing them again soon, try a bit less..

Try a crountry run with few uses of the brakes (unlike city driving) to see if the get hot from Braking or driving.Designing a new camper Heaps of choises

Your front hubs should only feel warm i.e. keep your hand on indefinately if adjusted/packed correctly. Too much grease causes 'churning' and heat generation, only pack bearings with a bit more around seals and FWH components.
Adust bearings with road wheel in place and tighten just enough to eliminate free play -- by rocking wheel. Maybe do one side at a time to see if there is a differance.

Guys is there a torque setting perhaps because it would be very easy to make a spanner up to go on a tension wrench?

The torque setting with new bearings may differ with bearings that have k's on them and you are only re-packing no replacing.

The feel method is by far the best with new or old bearings.

G'Day Quinno,

As Rox has mentioned, be wary of heat transfer from the front breaks, check them only after a fair run with bugger all breaking, around town mine are super hot and only luke warm on country trips.

G'day Quino,
You say in your post that you've "had new bearings put in", were they put in by you or someone else? If it was someone else, take the car back and let them feel the heat and ask them to fix it. I'm not too familiar with Patrol hubs but I reckon that they can't be too diferent to most FW hubs. If there is a lock washer between the tensioning nut and the lock nut, is it being used properly? ie: bent over both nuts so that neither of them can move?
