Vibration in first when pulling away under load.
Fourtrak 2.8TD 1991.
On my last holiday I was towing a loaded caravan probably no more than a tonne in weight. When pulling away in first the whole car vibrates violently. This doesn't happen in the other gears or if I pull away in first whilst in 4 WD. The only way to stop it was to hold the gear stick in first whilst pulling away. Another symtom, which may or maynot be part of the same problem, is that sometimes putting the gearbox in gear or pulling it out is extreamly (two handed tug!) difficult. I do need to take the box off soon as I need to replace the clutch as I suspect that the springs on the clutch housing have had it due to the fact that the car still tries to creep forward occasionally even with the clutch fully depressed. So I was wondering if there is something worn in the gearbox that I could replace whilst I have it out. Any pearls of wisdom would be greatly apreciated.
