After cleaning and washing the shafts, the universal joints are checked for ease and smoothness of turning the forks and for the absence of significant axial and radial clearances. Check the balance of the driveline on the balancing stand, as indicated below. If the turning of the forks is smooth, there are no jamming, the imbalance does not exceed 220 gf mm, the circumferential clearance in the spline connection does not exceed 0.30 mm, and no lubricant is ejected through the cross seal, then disassembly of the driveline is not recommended.
