Drive shafts transmit torque from the engine, transmission and differential to the front wheels (Fig. 9.28). In the gearbox drive shaft spline connection attached to the differential side gears. Fixation of the spline tip of the internal hinge of a power shaft side gear made snap ring. When installing the lock ring is compressed into the groove of the shaft. Once the shaft is fully seated in the side gear differential lock ring expands and fixes slotted tip from axial movement. External hinges are attached to the drive shafts of front wheel hub mounted on bearings. Fixing the shaft to the hub nut is carried out. The drive shafts of equal length to the intermediate shaft placed between the gearbox and the right drive shaft. CV joints protected by rubber covers that attach clamps and CV joints prevent contamination of water and mud. Cases must be periodically inspected for signs of damage, leakage of the lubricant or cuts. Damaged covers CV joints should be replaced immediately with new, or CV joints can be damaged. Replacing the cover includes surgery to remove the drive shafts. The most common sign of wear or damage to the CV joints, in addition to the leakage of the lubricant are clicks when cornering, under acceleration roar from the state of inertial motion or vibration at high speeds on the highway.

Main elements and arrangement of the shafts on vehicles with manual and automatic transmissions are shown in Fig. 9.29, 9.30.

To remove the shaft, do the following. Lift the front of the car, fix on supports, remove the front wheels and mudguards, drain the gearbox. A screwdriver inserted through the caliper, brake disc lock from turning and remove the hub nut. This nut is tightened strongly. When installing, use a new nut. Disconnect draft stabilizer, unscrew the ball joint nuts and bolts knuckle, remove the rack from the front suspension ball joint.

Remove the inner end of the drive shaft or the intermediate shaft of the transmission, which insert a tire lever between the gearbox housing and the housing inner CV joint (Fig. 9.31). Lightly tap on the blade assembly, remove the drive shaft of the transmission. Be careful not to damage the drive shaft seal. On models with automatic transmissions need to insert a chisel between the drive shaft and the casing, and then tap it easy to disconnect the drive shaft of the differential (Fig. 9.32). Tilt the hub outwards and disconnect the inner end of the drive shaft. Pull out the drive shaft from the hub, if necessary using a stripper. Support constant velocity joints and remove the drive shaft from the vehicle. Removing the intermediate shaft Lift the front of the car, fix on supports, remove the front wheels and mudguards, drain the gearbox.
A WARNING Each time you remove the drive shaft cover the hole in the gearbox casing. If you remove the drive and the intermediate shaft, be careful not to move the slots differential side gears. Insert a wooden plug or the like to hold the plug in place of the differential side gears. |
A screwdriver inserted through the caliper, brake disc lock from turning and remove the hub nut. This nut is tightened strongly. When installing, use a new nut. Remove the inner end of the right drive shaft from the intermediate shaft, which insert a tire lever between the bearing of the intermediate shaft and the housing inner CV joint. Lightly tap on the blade assembly, remove the drive shaft.

Remove the screws, remove the intermediate shaft from the gearbox and remove it from the vehicle (Fig. 9.33). To disassemble the intermediate shaft and the bearing replacement necessary tools for pulling out, the work entrusted to experts equipped garage. Installation countershaft

Before installing the intermediate shaft put a new lock ring on the drive shaft and the groove of the intermediate shaft, lubricate the splines with gear oil (Fig. 9.34). Insert the intermediate shaft in the gearbox, screw the mounting bolts and tighten them to the specified torque. Installing the wheel drive shaft Lift shaft supporting the SDC, and insert it into the hub and gearbox, or an intermediate shaft. Insert the drive shaft into the side gear differential, easily tapping it with a hammer through a wooden block. Pull out the hub to ensure reliable fastening of the inner CV joint in the drive shaft of the differential side gear. Position the steering knuckle and screw bolts knuckle to strut front suspension. Screw the new hub nut. A screwdriver inserted through the caliper, brake disc lock from turning and tighten the hub nut.

Hammer and chisel hammer in a nut fillet into the groove of the drive shaft (Fig. 9.35). Connect the stabilizer bar, install mud flaps and wheels fill the transmission hydraulic fluid and lower the car.
Replacement of a protective cover of the drive shaft Remove the drive shaft and secure it in the grip of two pieces of wood to protect the surface from damage.
A WARNING Before starting work, purchase the appropriate kit to replace the cover. The kit contains a special lubricant based paste Moly, required to fill the SDC. Another type of lubricant can be used. |
Cut the fixing collars cover and discard them. Slide the protective cover from the SDC to the drive shaft. Screwdriver, remove the retaining ring SDC large (if available). Remove the thrust ring and shifting, remove CV joint from the drive shaft splines. Remove the protective cover from the drive shaft.
A WARNING | Fig. 9.36. Boot band of the drive shaft
|
From the side of the wheel and the differential use different covers, so they can not be mixed (Fig. 9.36). |
Due to the fact that the removal and installation of the drive shaft rather labor-intensive, it is recommended to replace at the same time, both the protective cover of a power shaft, even if only one is damaged. Thoroughly clean the CV joints and shaft splines, inspect them for wear, damage, dirt and water. Replace any damaged items with new ones. Wrap the tape drive shaft splines to prevent damage to the surface of the new sheath during installation. Lightly grease the inner diameter of a new cover and put it on the drive shaft. Remove the tape, lightly coat with lubricant slots and set the CV joints and thrust washer cone side facing the shaft. Tamp SHRUS special lubricant based paste Moly. Install external retaining ring. Place the protective cover in the grooves of the housing and the drive shaft CV joints. Install clamp protective cover so that the key addictive closed in the direction opposite the direction of rotation of the drive shaft when the vehicle is moving.
