Driveline and wheel setup
Swapping to a Dana 60 front axle changes more than the axle itself. The heavier housing changes the load on the steering, the front driveline and the tires, so the complete front end should be looked at as one system. The shafts, U-joints and pinion yoke all carry torque through the front driveline, which is why the driveshaft is part of the planning.
Before installing, measure the existing wheel and tire setup against the 8 on 6.5-inch pattern and the axle’s brake size, since the brakes must clear the wheel. Look for wear on the old U-joints, bearings and axle seals at the same time, and replace worn parts while the axle is out. After the first few trail runs, re-check the axle and driveline bolts and the fluid level.
- Confirm wheel offset and backspacing for clearance
- Inspect the transfer case and driveshaft angles
- Check the differential fluid level after installation
- Replace worn U-joints while the driveline is apart
