Truetrac on both axles of my D90......observations after one day.

1)Pacific NW is mostly snow, gravel and mud. I am not a rock crawler.
2) On road impression: Very slight extra self centering feel on turning at junctions. No difference in normal corners. Only noticable if you had driven the Rover before the change. Not an issue. Tracks very straight and has less need for steering correction as road camber changes. Overall, different by less than 5%, but not a negative.
3) Off road, limited to a few laps of my muddy field. Very much improved traction, minimal wheelspin compared to open diffs. To make a lap I needed to use the center diff lock before the change, now with Truetracs I can leave center diff unlocked.
4)I like simple stuff that anyone in the family can drive. These are foolproof.

John

i thought leaving the center diff unlocked was risky in these trucks. is that only true if your open/open? i too like to keep things as simple as possible. helps figure our what's what when things break, right?

soory, i know this is an old thread.

Yes, even if you can make it, if there is mud or any slippage, you should lock the center diff.

can someone explain this to me?

I was taught to do this just to keep from tearing up the trail

What is the "risk" to the trucks by not locking the center diff? Obviously if you're spinning a lot you risk suddenly catching but "if there's mud or slippage" at all?

The center differential within the transfer case is a rather small, light duty, two spider unit. Excessive differences in front and rear axle speeds, combined with significant torque transfers tend to cause it to 'explode'. It was really only designed to allow for minimal differences in speed between the axles during daily driving duties (you know, going around corners on surfaces that will not allow tire slip easily)...

Be Safe, lock it up when you expect wheel spin of any kind...
