1. After cleaning and washing the shafts, check the cardan joints for ease and smoothness of turning the forks and for the absence of significant axial and radial clearances.
2. Check the balance of the driveline on the balancing wall as indicated in subsection 7.3.7.
3. If the turning of the forks is smooth, there are no jamming, the unbalance does not exceed 2.15 N·mm (220 gf mm), and the circumferential clearance in the spline connection is not more than 0.30 mm and no lubricant is ejected through the gland of the crosses, then disassembly of the driveline is not recommended.
