I read this on fourwheeler.com:
"With three different 4x4 systems the engineers found a way. With the Active Drive 1 system you are upgraded out of the 2WD status, but no low range is available. It is best for cute-ute buyers and mall cruisers or the occasional dirt road or trip to the ski resort. Next comes the Active Drive 2, which incorporates a low range of 2.92:1, effectively giving the Cherokee a 56.1 crawl ratio with the four-cylinder engine, which is even better than the (non-Rubicon) JK Wrangler. Finally, the Active Drive Lock 4x4 system (standard on the Trailhawk model) incorporates a locking center differential, sort of, a mechanical coupling instead of a viscous or clutch plate unit. But the best news, and the vehicle’s saving grace, is that the Trailhawk model also has a true mechanical locking differential (made by AAM) in the rear."
I haven't heard this before.....True?
