What is preload rear axle adjustment?

Bearings adjusted in preload are typical on pinion and ring gear shafts of heavy-duty axles. Preload is achieved by adjusting the bearings to a slight amount of bearing rolling torque. Rolling torque is a measure of a bearing’s resistance to rotate, indicating tightness in the bearing setting.

How do you find the preload on a bearing?

The requisite preload force can be estimated using:

  1. F = k d.
  2. a.
  3. i) Axial displacement method: The axial displacement method is based on the relationship between the preload force and the elastic deformations within the bearing arrangement.

How is preload differential calculated?

Measure the distance between the left and right bearing shoulders on both diffs. Then, measure the distance between the left shoulder bearing and the ring gear mounting flange. Adjust the bearing shims to put the ring gear in the original location and put the original amount of preload on the bearings.

Does a Dana 30 have a drain plug?
