Axles
Axles:

93-98 I6 Grand Cherokee's

D30 low pinion front axle
Differential Location: Drivers side
Stock axle splines: 27 (upgradeable to 30 splines)
Lug Pattern: 5 on 4.5"
Width: 60" from wheel mounting surface to wheel mounting surface
Notes: Stronger than earlier D30's. Decent for 33" or smaller tires. The u-joints are the main weak point but can be easily upgraded.
D35 c-clip rear axle
Differential Location: Centered
Stock D35 axle splines: 27 (upgradeable to 30 splines)
Lug Pattern: 5 on 4.5"
Width: 60" from wheel mounting surface to wheel mounting surface
Notes: Not a bad axle with 33" or smaller tires if left open. Many people upgrade this axle with 30 spline axles and lockers. However you'd be better off swapping in a stronger axle like a Dana 44a or Ford 8.8. The weak part of this axle is the axle tubes. Under extreme pressure they flex which results in broken axles or pinion failures.

93-98 V8 (5.2L or 5.9L) Grand Cherokee's

Dana 30 low pinion front axle
Differential Location: Drivers side
Stock axle splines: 27 (upgradeable to 30 splines)
Lug Pattern: 5 on 4.5"
Width: 60" from wheel mounting surface to wheel mounting surface
Notes: Stronger than earlier D30's. Not a bad axle with 33" or smaller tires. The u-joints are the main weak point but can be easily upgraded.
D44a "aluminum center section" rear axle
Differential Location: Centered
Stock axle splines: 27 (upgradeable to 30 splines)
Lug Pattern: 5 on 4.5"
Width: 60" from wheel mounting surface to wheel mounting surface
Notes for D44a: Not a bad axle with 33" or smaller tires but can handle 35's if driven with care. The aftermarket support is very limited for this axle due to the aluminum center section. The center section is very similar to the unit in the corvette. Many people replace the axle due to the limited gear ratio's available and the extremely limited availability of any traction device such as a locker.
