I have been told to use full time 4 wheel drive all the time - I had figured out 4 wheel drive in the damp after nearly spinning in the local Sainsburys car park on a damp patch in 2wd.  What about part time - if I try this a get a rubbing noise from the LHF side, CV joint possibly? but no noise when in full time 4wd.  I have also been told that full time 4wd does not impact economy anyone confirm this? New owner confused!  :?

I run both the XJ's in 4 wd all the time no problem with fuel. maybe 10% different if in 2 wd. But others may have better idea's.

Part Time 4x4 can only be used off-road on slippery surfaces, since the front and rear axles are locked.  Using on tarmac may result in expensive breakages.

Full time 4x4 can be used anytime, since there is a differential between the front and rear axles to prevent axle wind-up.  Some people reckon using 2wd may gain them an extra couple of mpg, but the downside is you get rear wheel drive handling issues, especially on wet and icy surfaces.

The secret is to remember that you're not driving a car anymore. Read the road and you'll be fine in 2WD. Just remember that you haven't much weight at the back end to give you traction.

As said above, if you feel safer in full time 4wd, that's fine, you'll do no damage, just don't let it give you a false sense of security. Expect about 1-2mpg better economy in 2WD.

RWD handling issues  what are they ? please explain !!!!!

IMHO it's nice to have the tail sliding and drifting sideways, but there again i'm used to it

thats a big 10 4

Thanks for the advice - 2w/d in the summer then unless it's like this year when paddles would have been better!

2wd great for rear wheel drofting in the wet, the jeep is very stable even with a lift kit fitted, still drive mine like it's a sports car.

4wd great for traction in all aspects especially the wet but be carefull when it slides as it bites back harsher than 2wd

Full Time 4x4 used at all times, except when off-road, for me. Little difference in fuel comsumption (did a test), so why not make use of it? Handling is much better IMO.
