Nissan 37200-ZP90A Shaft Assembly PROPELLER

The drive shaft is of significant importance, as it transmits power between the transmission or transfer case (on 4WD models) and the differential and is characterized by universal joints at each end and a centre support bearing in the event of a two-piece drive-shaft. In the single piece rear drive shafts, the one at front has a splined yoke that connects to either the transmission or else the transfer case while the rear portion possesses a splined yoke that joins the front section, allowing for suspension changes. The two-piece rear driveshaft model has a center support bearing attached to a frame crossmember. Because of suspension movement, the 4WD front driveshaft contains a slip joint. When problems occur throughout their service lives, drive-shafts typically require little servicing, as they contain permanently lubricated universal joints that need to be replaced only after issues have been identified which necessitates removal of this part for servicing. Take good care to balance accurately without any debris being stuck on it while balancing weights should be secure. As soon as noise or vibration is noticed during driving, an immediate attention is needed including road testing for confirmation. Do not forget to inspect the driveshaft for dents or cracks under proper vehicle raising conditions plus both ends must be checked for oil leaks during servicing. While doing this check ensure smooth operation of universal joints with no binding noises or looseness; examine center bearing in terms of wear which might affect it plus rubber section for cracks. Try to twist or lift it up so as to ascertain whether there is any movement hence verify that there is no disintegration within universal joint(s). Finally check whether driveshaft mounting bolts are tight enough also. For 4WD models perform these checks again but on front driveshaft including checking slip yoke for leaks too. Also scrutinize all connections from driveshafts into transfer case and front differential input where oil sealings get outworn as well as front drive axle joints tend to get loose with grease and oil leakage from rubber boots.

Raise the vehicle and support it securely on jackstands. Place the transmission in Neutral with the parking brake off. Make reference marks on the driveshaft flange and the pinion flange in line with each other. Remove the rear universal joint nuts and bolts. Turn the driveshaft (or wheels) as necessary to bring the bolts into the most accessible position. If you're working on a model with a two-piece driveshaft, unbolt the center support bearing from the crossmember. Lower the rear of the driveshaft, then slide the front yoke out of the transmission or transfer case. Wrap a plastic bag over the transmission or transfer case housing and hold it in place with a rubber band. This will prevent loss of fluid and protect against contamination while the driveshaft is out. Remove the plastic bag from the transmission or transfer case and wipe the area clean. Inspect the oil seal carefully. Slide the front yoke of the driveshaft into the transmission or transfer case, being careful not to damage the seal in the process. If you're working on model with a two-piece driveshaft, raise the center support bearing into position, install the fasteners and tighten them securely. Raise the rear of the driveshaft into position, checking to be sure the marks are in alignment. If not, turn the rear wheels to match the pinion flange and the driveshaft. Install the new bolts and nuts, tightening them securely. For 4WD models, raise the front of the vehicle and place it securely on jackstands. Remove the skid plate, if equipped. Mark the relationship of the driveshaft to the front differential companion flange and to the transfer case companion flange. Remove the bolts and nuts from the flanges, then lower the shaft from the vehicle. Attach the ends of the shaft to the differential and transfer case companion flanges, install the new bolts and nuts and tighten them securely. Install the skid plate if equipped.

Slide the front yoke out of the transmission or transfer case.

A driveshaft is a vital component responsible for transmitting power between the transmission or transfer case (in 4WD models) and the differential, featuring universal joints at both ends and, in the case of two-piece driveshafts, a center support bearing.
