GQ Swivel hubs gets very hot

I had a look and have located it....thanks for that. Other than the unit and all that goes with it covered in dust/dirt it looks like the factory original and no additional adjustments have been done. the only thing I did noticed was the adjustment screw where the arm pivots is not sitting on the arm. there is a bit of movement before the arm actually touches the adjustment screw (at least a couple of mm) The spring is tensioning the arm, meaning the surface of the arm and the head of the adjustment screw does not touch.

I read another thread about proportioning bracket and how to check if mine required such a bracket. After checking mine in relation to the thread I think it does need a bracket to allow for the lift as the spring is not 90 deg to the valve. Will look at making up a bracket as I have some scrap steel and then take the truck out for a test.

Yeah, that might be a good idea.

You can close that gap by turning the screw and see what happens when you brake.
I think it is related to the odd angle created by the lift.

I've never touched or adjusted the proportioning valve in mine, and it's about time I have a good look at mine as well.

thanks....will look at making a bracket today. shouldn't be too difficult. will post a picture when done.

dom14...you were correct to note that the gap was due to the lift with no bracket to compensate for it. Made the bracket, put it all back together and yup.....no gap. please find attached photos to show progress and end result.....now I will need to take the patrol for a drive and see.

A quick word of advice just in case the temptation arises... do NOT blindly adjust that bolt on the proportioning valve.

Quick linky thingy that explains what it does... http://www.stoptech.com/technical-su...tioning-valves

hey....many thanks for the link....it certainly is a lot of information to digest. one good thing...I did not have to adjust anything at all. By making and installing the bracket it resulted in the adjustment screw to be back in plain with the arm. So I am absolutely happy with the end result. Have not had to chance to take the bus out for a drive...will probably do it this evening. will be looking out for stopping ability and of course the temperature in the free wheeling hubs. many thanks for all the help and information....couldn't have done it without all the invaluable feedback. will post the results soon.
