hi everyone, i'm a new member so i'm hoping someone can help with a problem.

I own a Isuzu Trooper 3.1 Td Duty R reg 98 and the four wheel drive doesn't appear to be working problerly (but it could just be me!). On slippy ground the rear wheels spin and the front wheels are stationary when in both 4H nad 4L. Have read in the owner's manual about locking hubs and on-the-fly models; first question how do you know which version you've got? second question - the alloys are not original and appear to have no locking mechanism on the front, could this be because they are just different alloys not allowing access to the locking mechanism?

need to know because i use the vehicle on the croft and at the mo it won't perform and have to resort to trusty beat up old P reg landy, series 3!

cheers all

Hi Mat,

The question regarding the hubs is a simple one... here are pics of the two kinds. Its also worth checking the manual lockers are not hidden behind the alloy centre caps Rolling Eyes

Locking:

Auto:

Note: pics show Toyota - Isuzu are pretty much the same.

cheers chris, thanks for the swift info. i've not actually taken the wheel off yet but was going to tomorrow - i have had the centre cap of the alloy off and there is nothing that resembles the mechanism as in the pic/manual. the only other bit of info i have is that the four wheel drive indicator light on the dash is never on apart from at 'lamp test' when vehicle is first switched on.

it seems a strange one as i know it should be straightforward as you say. any more help much appreciated as i'm at a bit of a loss mate

Aha... if the lamp is not lighting on the dash and your hubs are auto then get underneath and check the wiring on the front diff - the little plugs have a habit of breaking/corroding etc. There are plenty of other posts about this in the Gearbox/drivetrain section.

That's interesting. You can see the auto hub poking out on the Toyota photo, but on the standard Bighorn alloy, the wheel centre is flush...no hub to be seen! Confused

I would imagine at that age you will be looking at shift on the fly. Check the connections to the solenoid on the front axle as these can come adrift, also you have vacuum hoses too check these are ok also and I believe there is a switch on the transfer lever too.
