I have a 2002 disco. Recently I went off roading primarily in mud, I had the truck on low gear. I noticed when truck got stuck in mud, the front tire was spinning and the rear stayed still. Is that normal? I always thought the truck was 4 wheel fulltime and all wheels spun. | ||

Full-time four-wheel-drive does not mean all four wheels all the time.... The center differential splits power, sending part of it to the front axle and part to the rear axle. If you had a CDL (which a 2002 Disco doesn't), then you could lock your center diff, forcing half the power to the front and half to the rear, thus ensuring that at least one wheel on each axle would be powered. If you were in a D1 instead of a D2, and had the center diff locked, and then happened to have had either a Detroit locker or an ARB in the rear diff, then both of your rear wheels would have been turning in addition a front wheel; add an ARB or a Tru-Trac to the front diff, and you could have had all four wheels turning. With your D2, you have ETC, where the braking system tries to hold one wheel and lets the others turn, etc., to replace locking diffs. It works, it works well, but is not as competent as a center locking diff with additional lockers in the axles. -L | ||

Where would you use low gear as opposed to higher gear? | ||

I almost always switch to low range when off-road. It slows the vehicle down, so that you have more use of the power band at non-highway speeds... you get to make better use of your torque. Remember the addage "As slow as possible, as fast as necessary". You're not in a race out there (most of the time, at least)... take it easy and enjoy your time.... -L | ||
