Question about Off-roading and 4x4

I have a 1998 Grand Cherokee with the I-6 and Selec-trac. Im going to be doing some off-roading soon in some sand dunes in Silver Lake, MI. So, my question is what 4x4 mode do i want it in full time or part time. Is one better or worse for the engine? I know i wont need to be in 4-low for sure. Thanks for the help.

Use Part Time 4WD in the sand. Neither mode affects the engine any differently. The engine doesn't care what mode you are in.

Go with part time as it locks the driveshafts. Sand is plenty loose to prevent binding.

Depending on how loose the sand it you may want to air down too.

I've used part-time in St. Helen (Mi). Had no binding and went through the sand with no probs.

Any time I am in sand I put it in 4 low ...It gives you better throttle response and torque...

But Part time should work fine...

You would prolly want low range if your goin after the big dunes and need the extra torque. Silver lake is a blast, been there twice, once with a dune buggy, once with the ZJ.
