Axle & Driveshaft Upgrades
This is one area that you should consider seriously upgrading once you start running big tyres and pushing boundaries. While the JK Rubicon’s are blessed with larger axle shafts, front D44 Crown Wheel and pinions and lockers out of the factory, the majority of Wranglers remain sport models with an open D30 front, 30 spline rear shafts and no lockers. If treated with “Mechanical Sympathy” when wheeling they can serve you well and normally go the distance but once you get your confidence and skills up you often find yourself outdriving the ability of the vehicle. This is pretty much the case with any Jeep (or 4x4 for that matter) and you can quickly find yourself doing damage to the driveline when offroading.
Wheel slip/wheel spin is the biggest killer of drivelines. The massive forces placed on the relatively small internals can quickly disintegrate your spider gears, uni’s and twist axles. Sometimes your might not even realise you've done some damage, but a week or two later driving around town the problem can rear its ugly head with expensive repair bills.
Look at it this way, spending money on upgrading your driveline’s strength is purely an insurance policy which gives you some peace of mind when your off playing in the good stuff!
