The defect
Mci IS recalling 103 my 2005-2008 d4500 and d4505 coaches equipped with detroit diesel series 60 engines and a zf transmission. customers may experience a possible interference between the drive shaft u-joint bearing cap bolts and the tag axle center beam assembly.
The risk
Interference between the bearing cap bolts and the axle center beam assembly could cause the bearing cap bolts to shear, freeing the bearings and possibly releasing the drive shaft, increasing the risk of vehicle damage or a crash.
The remedy
Dealers will install a tag axle suspension spacer kit and an spl250 driveshaft retrofit kit to limit the suspension travel and reduce the swing diameter of the driveshaft thereby increasing the clearance and eliminating any possible interference. the recall began on february 25, 2009. owners may contact mci at 1800-241-2947.
