Download Propeller Shaft & Differential Carrier (Section PD)
Manual Description
PINION GEAR HEIGHT AND PINION BEARING, noise, Vibration Harshness (NVH) Troubleshooting, center bearing mounting (insulator) cracks, damage deterioration, excessive center bearing axial end play.
Use the chart below to help you find the cause of the symptom, if vibration is present at high speed, inspect propeller shaft runout, final drive companion flange with hands, if runout exceeds specifications, disconnect propeller shaft.
Final drive companion flange; then rotate companion flange, inspect propeller shaft tube surface dents cracks, if damaged, replace propeller shaft assembly, if center bearing is noisy or damaged, replace center bearing.
Put matchmarks on flanges and separate propeller shaft, draw out propeller shaft from transmission plug up rear, end of transmission rear extension housing, if the play exceeds specifications, replace propeller shaft.
Put matchmarks on shaft flange yoke, remove pushed out journal bearing by lightly tapping yoke, with a hammer, taking care not to damage journal yoke, put marks on disassembled parts so that they can be reinstalled in their original positions which they were.
When assembling, be careful that needle bearing does not fall, select snap ring that will provide specified play in axial direction of journal, install them, select snap rings with a difference in thickness both sides, adjust thrust clearance between bearing and snap ring zero.
Check to see that journal moves smoothly check axial, *: Always check with the Parts Department for latest parts information, the actual shapes of Kent-Moore tools may differ from those of special service tools illustrated here, measuring pinion bearing preload total preload.
(To use, make new hole, removing and installing propeller shaft lock nut, removing and installing drive pinion rear inner, removing and installing differential side bearing.
Installing pinion rear bearing outer race, installing pinion front bearing outer race, adjusting bearing pre-load gear height, refer to NVH TROUBLESHOOTING CHART”, PD-3.
Apply multi-purpose grease to cavity at sealing lips oil seal, press front oil seal into carrier, install companion flange drive pinion nut, remove rear cover rear cover gasket.
Install new rear cover gasket rear cover, fill final drive with recommended gear oil, ¼ Remove front final drive mounting bolts, be careful not to damage spline, sleeve yoke front oil seal.
Before disassembling final drive, perform following inspection, a) Turn drive pinion in both directions several times set bearing rollers, b) Check total preload with Tool, ring gear drive pinion backlash.
Check backlash of ring gear with a dial indicator several, check runout of ring gear with dial indicator, side gear to pinion mate gear backlash, using a feeler gauge, measure clearance between side gear.
Clearance between side gear thrust washer differential case, using three spacers [20 mm (0, put matchmarks on one side of side bearing cap with paint.
