| | Beefing the NP231 Transfer Case |
 | | Exploding your truck's transfer case can really be a drag, whether you're on the trail or just flat-towing your 4x4 down the road. |
 | | The NP231 transfer case found in many late-model Jeep, Dodge, and GM vehicles has a fairly good reputation for a chaindriven, aluminum-cased unit, but improper towing procedures can cause it to explode, and some of the internals are iffy for big tires and lots of torque. |
 | | This notch in the case half is the result of a worn-out and loose drivechain eating away at the aluminum as the chain flops around. |
