Solution
Tighten bolts to specified torque. Remove companion flange, turn 180 degrees from its original position lubricate splines and reinstall. Tighten pinion nut to specified torque.
Problem
Roughness at low speed light load at 15 to 35 mph or 24 to 56 kph.
Cause
U bolt clamp nuts excessively tight.
Solution
Check and tighten to specified torque. If torque was excessive or if brinelled pattern on trunnions. Replace U joints.
Problem
Scraping noise.
Cause
Oil slinger, companion flange or end yoke rubbing on rear axle carrier.
Solution
Straighten or replace oil slinger, companion flange or end yoke rubbing on rear axle carrier to remove interference.
