Removal

PERFORMANCE ORDER
1) weaken bolts of fastening of wheels
2) remove a nut or a bolt of fastening of a nave of a wheel / half shaft (the car has to stand at the same time on the earth)
3) remove a washer
4) remove a wheel
5) remove bolts of fastening of a support of a brake and a support (average shooters)
6) remove a brake disk

8) remove a bolt of fastening of the spherical hinge to a rack of the wheel bearing (it is specified by the lower arrow)
9) remove cross draft
10) remove a nut from connecting draft (it is specified by an arrow)
11) wring out by means of the lever the lever of a forward suspension bracket down to disconnect the spherical hinge from a rack of the wheel bearing

Prevention

At removal of the spherical hinge, turn a steering wheel here and there (you will need the help of the second mechanic).


12) by means of a stripper remove a half shaft from a nave

Prevention

At removal of a half shaft use only a mechanical or hydraulic stripper. Do not heat a rack of the wheel bearing as you can damage the bearing.
