The new grill probably allows for more cooling. Also they probably are using the 392/4xe/XR rear brakes to get that rating... but likely a little bit of everything (including the previous measurement being conservative).
I recall reading that all models would now have the larger brakes from the 4xe/392
Even 2-doors?
I thought I read they are adding a tow-haul mode to the jeep. Maybe I miss read it?
Towing capacity for the European market on the current JL Wrangler is 5500LBS. It's exactly the same Wrangler that's sold here with the exception of some non-towing related stuff. You're fine capability-wise. Though there's plenty of speculation about whether or not you should exceed the US spec when towing.
Even a sport jlu gets a 5k tow rating in Europe and Australia, it was never about the axle.
I believe so. But information is still kinda murky at this point.
I've read that one of the strength improvements on the current 44 vs the JK era 44 was larger carrier bearings. The current semi float axle shaft has the potential of bending between the wheel flange and the single hub bearing, because it sees both vehicle weight and torsional loads. The full float has a dual opposed hub bearing setup to fully support the wheel end, allowing the axle shaft to only see torsional loads.Even though pinion and gears are likely the same. Im guessing the full float means near zero flex and load across the axle now the wheel load and some flex is removed. Perhpas reducing axial loads on the carrier and gears?
Or am I talking crap?
I fully believe it has been 5k on the 4 doors all along as in England the current JLs are rated at 5k. They have less restrictions to an extent on certain vehicle functions. So we either had a government policy change here recently in the states or there is truly something in regards to the new axles.
