Maintenance And Service
Studs, lugs and wheels can be damaged by over tightening.
Do not over tighten wheel lugs.
9.3.2 DISK WHEELS Lug nuts are prone to loosen right after a wheel is mounted to a hub. When driving on a remounted wheel, check to see if the lug nuts are tight after the first 50-100 miles of driving and weekly thereafter.
Lug nuts are prone to loosen after being first assembled. Death or serious injury can result.
Check lug nuts for tightness on a new trailer, and after re-mounting a wheel after the first 50-100 miles and weekly thereafter.
1. Place two drops of oil to a point between the nut and flange and two drops to the two or three threads at the end of each wheel stud.
2. Tighten to 50 lb/ft of torque in the sequence shown in figure 9-1.
3. Tighten to 450-500 lb/ft of torque in the sequence shown in figure 9-1.
