The drive is transmitted from a transmission to wheels through half shafts. The internal ends of half shafts through shlitsevy connection fasten to gear wheels of half shafts of differential. The external ends of half shafts through shlitsevy connection fasten to naves of wheels and are fixed by nuts.
On the internal ends of half shafts the sliding hinges of equal angular speeds (HEAS) which are capable as to axial, and angular movement are installed. Each of internal the CV JOINT consists of a tripod with three bearings and a hinge casing (which the role of an external path of swing plays), in which tripod can move back and forth at the movement of a half shaft together with a wheel up-down. Hinges can be sorted and cleared in case of damage of a cover, however, at damage of the hinge, any of elements, all hinge needs to be replaced.
External the CV JOINT are Universal Rzeppa hinges and consist of ball-bearings in which balls rotate between an internal path of swing and the external case which is capable to angular, but not axial movement. External hinges need to be cleared, checked and filled with new greasing, but they cannot be disassembled. If the external hinge is damaged, it needs to be replaced together with a half shaft (external hinges are on sale only together with a half shaft, as a unit).
Covers of hinges need to be checked regularly for existence of damages or leak of greasing. The torn covers need be replaced immediately, otherwise, hinges can be damaged. For replacement of a cover it is necessary to remove a half shaft.
It is possible to find the putting-on covers for which installation it is not necessary to remove a half shaft in sale. It is rather convenient alternative; however, the half shaft needs to be removed, and the hinge to sort and clear to check, whether moisture or dirt which will accelerate its wear got to the hinge.
The main signs testifying that the hinge is worn-out or damaged are, besides greasing course, knock at turns, acceleration and vibration at high speeds.
For check of wear of the hinge and half shafts, undertake a half shaft and try to rotate it in both directions, holding casings of hinges. If you feel existence of a free wheeling, it testifies that vents or hinges wore out. Also, examine a half shaft on existence of cracks, dents and deformation.
| PERFORMANCE ORDER
| 1. Disconnect a wire of the negative plug of the accumulator.
If the stereoplayer of your car has system of the coding, check, whether you know a code of activation of the player before an accumulator detachment.
| 2. Put the car on the emergency brake.
| 3. Turn off nuts of fastening of forward wheels, lift the car and establish it on support. Remove wheels.
|4. Get to the check (to a photo at the left) and remove a cap from a nut of fastening of a half shaft (a photo on the right).
|5. Turn off and remove a nut of fastening of a half shaft and a washer. In order that the nave did not rotate, insert lomik between bolts of fastening of wheels and establish the second end of a lomik so that it rested against a floor or the bottom of the car.
|6. To get a half shaft from nave shlits, strike on the end of a shaft with a hammer with a brass head or use to copper small beards.
If you make too big effort for a half shaft, you can damage it or a transmission. If the half shaft very densely sits in nave vents, and you cannot beat out it, you should remove a brake disk (see subsection 9.7) and to squeeze out a half shaft by means of a two-foot stripper after implementation of point 8.
|7. Remove engine filters (see subsection 126.96.36.199.1). Install the pallet under a transmission for collecting oil which will pour out at removal of a half shaft.
|8. Turn off the nuts and bolts fixing the spherical hinge to the suspension bracket lever, then lower the suspension bracket lever to disconnect it from the hinge (see subsection 10.5).
|9. Turn a rotary fist and get a half shaft from a nave. Do not allow the external end of a half shaft to hang on internal the CV JOINT, so it will lead to an exit it out of operation. Suspend the external end of a half shaft by means of a wire if it is necessary.
|10. Accurately get the internal end of a half shaft from a transmission, having wrung out the internal CV JOINT.
|11. Procedure of replacement of an epiploon of a half shaft is described in chapter describing a transmission.
| PERFORMANCE ORDER
| 1. Installation is carried out upside-down removals. At installation pay attention to the next moments.
| 2. Sharply insert the internal end of a half shaft into a transmission in order that the lock ring on the end of the internal hinge got to a flute on a differential half shaft gear wheel.
| 3. Tighten a nut of fastening of a half shaft till the demanded inhaling moment (see subsection 8.1), then establish a cap of a nut and new to the check.
|4. Establish a wheel and acquire nuts of fastening of a wheel, lower the car on the earth and tighten nuts till the demanded inhaling moment (see subsection 10.1).
|5. Check oil level in a transmission or a case of differential and add if it is necessary, to the demanded level (see subsection 2.3)
