Connect bearing support toģ) Ensure that front face of bearing support is perpendicular On most models with 2-piece shafts, proper phasing is accomplished by keys on spline and slip joint.Ģ) On models with 2-piece shafts, rotate transmission yoke 2: Slip Joint Alignment Arrows Align arrows for proper shaft phasing.ġ) All General Motors models with 32 splines use keys on spline and slip joint, which can only mate in correct position. If flanges are not in same plane, disassemble universal joint and align.įig. Often there are arrows on slip joint and drive shaft to aid in alignment. Check for loose bolts and worn bearings.Ĭheck that flanges on either end of drive shaft are in same plane. Universal Joints - Check for foreign material stuck in If mountings are deteriorated, replace them.ĭrive Shaft - Check drive shaft for damage or dents thatĬould affect balance. If bearing insulator is deteriorated orĮngine & Transmission Mountings - Tighten mounting bolts. Tires and wheels - Check tire inflation and wheel balance.Ĭheck for foreign objects in tread, damaged tread, mismatchedĬenter Bearing - Tighten drive shaft center bearing Before overhauling driveline, check other sources of possible vibration as follows: 1: View of 5 Commonly Used Drive Shaft Combinations Many 4WD models use 3 drive shafts. Location of slip joints varies with model and manufacturer. Three shafts are used in many 4WD applications. Number used in vehicle varies: one shaft, 2 shafts with a center bearing, or 3 shafts. ![]() Drive shafts are balanced, one-piece, tubular shafts with universal joints at each end. ![]()
