Honda 8-97180-423-0 Shaft Assembly, Front Propeller

To change the front driveshaft on 4WD models raise the front of the car and support it on jackstands and to orient the front driveshaft flange and the front differential companion flange and the direction the front driveshaft faces. Also note the orientation of the U-joint where it attaches to the driveshaft and at the other end. Subsequently, align the rear driveshaft flange to the transfer case companion flange and make the respective marks. Screw and tighten the lock to ensure that the drive shaft does not rotate, and then remove the four nuts and bolts which are used in the front flange, and those four nuts and bolts used in the rear flange should also be removed while supporting the transmission with a jack if needed. Pull the splined end to the rear until the rear end of the front portion of the driveshaft reaches the rear end of the other driveshaft then take the driveshaft out from the vehicle. In case of installation, there is a reverse process to be followed, however, verification of the position of marks must be done and the flange bolts must be tightened to the correct torque value. To get to the rear driveshaft, lift the rear of the car and provide it with support using jackstands; if in the model of your car there is such a thing as the center support bearing bracket attached to the frame, then remove its bolts. The relationships between the U-joint and the driveshaft and flanges should be marked out to allow for reassembly of the same. This has to be removed by the four nuts and bolts to detach the rear driveshaft from the rear axle or the transfer case. On the 2WD models only: Rest the driveshaft, take the yoke out of the trans extension housing and pull the yoke. In case of automatics and 4WD models, shift the driveshaft slightly to the side and U-joints are released and the whole set up is slid out in unison. Thread a plug in the transmission to illustrate how to cope with leakage of lubricant on the 2WD models. Reinstallation is done in the reverse order to the removal with especial attention to ensure that the flange marks meet and the center bearing support bolts are tightened while at the same time ensuring the bracket is perpendicular to the driveshaft.

Several driveshaft assemblies are used in the vehicles and all Rodeo has a driveshaft come with a center bearing while the Amigo comes with a single piece driveshaft with no center bearing. The driveshafts for 2WD manual transmissions have a slip yoke at the extreme end of the extension housing, and are attached to the pinion flange at the differential end, and has two universal joints-one at the slip yoke and the other at the rear end of the shaft where it connects to the pinion flange. On the other hand, those for automatics and 4WD fix to flanges in the extension housing and the differential; the slip yoke is behind the center bearing in the rear section. Two-piece driveshafts with a center bearing feature three U-joints: At housing of companion flange is one, behind the center bearing is one, and at the pinion flange of the differential is one. Also included is front driveshaft that links to a flange on the front of the transfer case as well as a pinion flange at the front axle differential; both ends of the former come with two U-joints. Every U-joint is serviceable separately from the shaft; the driveshaft has to be reassembled and put back in its original order, otherwise, the excessive vibration is hardly avoidable. The rear axle is described as semi-floating, and here the axleshafts sit across the vehicle, with the housing being taken up by the suspension arrangement. The differential in the centre of the rear axle transmits the turning force coming from the driveshaft to the axle halves, which are splined to mesh with the differential gears; the outer support is available from the rear wheel bearings that are pressed onto the axle shafts. Front axle structure of the 4WD vehicle is a differential assembly mounted on the frame and two driveaxles, having constant velocity joints at its two ends for transmitting power from the transmission to wheels at different suspension angles. Because of the sensitive nature and complexity of differential, together with the need for special tools, it is best that any disintegration of the differential to be in the hands of a dealer or a professional repairshop.
