Axle & Differential Parts for Jeep CJ7

Why Axles and Differentials in the Jeep CJ7 Need Attention Over Time.

The front axle, rear axle and driveshaft together form the drivetrain of the Jeep CJ7, transmitting the engine's full power to the road or the trail. The Dana 30 front axle and the two rear axle options, AMC 20 and Dana 44, are constantly exposed to rotational, bending and shock loads that gradually wear axle shafts, ring and pinion sets, wheel bearings and differential components. Seals at the axles and driveshaft harden and start leaking, U-joints lose grease and begin to clunk, and differential side bearings lose precision from frequent traction changes. These loads add up quickly, especially with off-road use, larger tires or axle swaps. Regularly checking for play, leaks and unusual noise helps avoid costly damage further down the drivetrain.

• Front Axle Dana 30: Parts for the Dana 30 front axle – axle shafts, ring and pinion sets, wheel bearings and yokes for the standard front axle.
• Rear Axle AMC 20: Parts for the AMC 20 rear axle – axle shafts, wheel bearings and Trac-Lok differential components for the standard rear axle.
• Rear Axle Dana 44: Parts for the Dana 44 rear axle – the sturdier alternative with ring and pinion sets, wheel bearings and yokes for more heavily loaded vehicles.
• Drive Shafts: Parts for the driveshaft – U-joints, propeller shafts and yokes for power transfer between the transmission and axles.

American Axle Engineering from Proven Brands.

Across all four categories, Crown Automotive and Dana Spicer supply the bulk of the axle shafts, ring and pinion sets, wheel bearings, yokes and differential components – both stand for American engineering and precise US-made quality. The range is rounded out by wheel studs from Dorman and select ring and pinion variants plus the rear propeller shaft from Omix.
