Hi all, hope you've enjoyed playing with your troopers/bighorns in the snow - I'll bet all those holier-than'thou car drivers are sick with envy watching us climb snowy hills while they wheel-spin at the bottom Evil or Very Mad

Anyroadup, after playing in 4wd Hi and Lo for a couple of days in my Bighorn, I deselected and went back to 2wd, reversing the cursory 3 or 4 yards to disengage as was the norm in my old 2.8. However, out on the road there was a whining, scraping sound as if something was trapped on the disc, accompanied by a bumping like when you drive over a sharp-edged stone or summat. Re-engaging 4wd cured the problem but I'd like to use 2wd for fuel economy and speed. I'm thinking that 4wd hasn't released properly and that the second diff is slightly engaged - hence the bumping feeling like when a gear jumps. Anyone got any ideas or advice? It may be that it'll cure itself over the next few days, but at the moment I'm fearing a lying-down-under-the-Troop-in-the-snow kind of job. All replies gratefully received. Smile

Cheers, Leo.

We had that when we pulled someone off the green outside our house (wont do it again got no thanks for it) and thought we'd done some real damage to car. It was a horrible noise like you describe. Hubby came back after going round block and picked me up and took me, really frightening. Could see £signs going round thinking of expense.

All we did was put it back in 4wd and then back in 2wd drive again and it cured it. Not done it again but have heard that what you have to do.

Thanks Ethel, I kinda figured that's what I'd need to do. As for pulling cars out of snow/mud etc, I went caravanning (I pull a twin-axle 23-footer@ 1.5tonnes loaded) and did my noble gent thing by pulling a huge motor-caravan out of the mud. As soon as I'd taken the tow-rope off his van he scarpered! Still....we'll probably help the next poor soul anyway cos us Trooperites are good people! Wink

We said the same. We pull a caravan dont even know its on back, ever so easy to get carried away, really good tow cars.

Hope your problem is sorted

Yes - problem apears to have sorted itself - I think I panicked a bit at the thought of spending money Embarassed

. I had previously selected/deselected 4wd loads of times to no avail, but I've just been out and 2wd is working fine - and nice and quiet too. Thanks for the advice Ethel.

No problem glad to be of help. My first thought was the cost cos we'd not long had an engine rebuild on a 3.1TD 1993 trooper.

I have a similar problem going from 2wd to 4wd. Returning to 2wd cures it. I'll give it a go again tonight to see if it still happening but wondered if any technically minded person may be able to explain what the actual problem is.?
