I have a 1987 manual gearbox model with manual hubs, the problem is that there is no 4wd.When i tried to lock the hubs, the passenger side one was very stiff and i had to use pliers to get it to move. When i move the transfer lever to 4L, the front prop shaft does turn when the vehicle is driven but the car stays in 2wd, a mate watched as i drove slowly. Also the 4H button on the dash does not seem to do anything and also, the indicator light does not illuminate at all.
My other problem is that it ticks over at about 800rpm and gradually creeps up to about 2000rpm, at junctions and traffic-lights etc. This is making it difficult to change gears and is also making fuel consumption very high.Hoping that someone may be able to help
