Removal and installation the front suspension (VAZ-2101)

To remove the front suspension, place the vehicle on a lift or inspection pit, apply the parking brake, remove the front wheels and, holding them with the A.50070 key, (6mm wrench) end of the rod by the flats, disconnect the upper end of the shock absorber. Having bent the locking plates, unscrew the bolts fastening the caliper to the bracket, move the caliper to the side and secure it so that it does not hang on the hoses. Remove the shock absorbers with brackets. Disconnect the ends of the anti-roll bar from the lower suspension arms. Using puller A.47052, press out the pins from the holes in the arms and move the steering rods to the side. This puller has the shape of a cup with a diameter of 48 mm with a beveled bottom, in which a radial groove 17 mm wide is made. An M22x1.5 screw is screwed into the cup.

Insert screw 2 (Fig. 105) of device 67.7828.9504 (Fig. 106) into the hole of the upper support of the suspension spring, and place it on the spring coil 3 from below (see fig. 105) and on screw 2 support plate 1 and fix it on the spring with a clamp. From below, screw a nut onto the screw so that its lock goes into the socket of plate 1. Turning screw 2 with a key, compress the spring until the suspension arms are completely unloaded. Remove the axle of the upper arm and disconnect it from the body. Disconnect the axle of the lower arm from the crossmember and remove the suspension unit from the car. In this case, it is necessary to note the number and location of the washers between the axle of the lower arm and the crossmember, as well as the adjusting plates between the crossmember and the body side members, so that when installing the units, put the washers and plates in their original place. Then remove the spring, smoothly unloading it, remove the device and repeat the operations on the other side of the suspension.







Remove the mudguard and stabilizer bar. Support the engine with a crossbar A.70526 or a hoist and remove the crossmember.


Installation of suspension units and parts is performed in the reverse order of removal. In this case, springs of the same group are installed on the front and rear suspensions (group A is marked with yellow paint, group B - green). In exceptional cases, it is allowed to install group A springs on the front suspension, and group B springs on the rear. If group B springs are installed on the front suspension, then springs of the same group are installed on the rear suspension.

To prevent incorrect distribution of forces in rubber-metal hinges, tightening of nuts and lever axles is performed in the following order:

• place the car on a level surface and point the wheels straight ahead;
• load a car weighing 320 kgf (4 people + 40 kg in the trunk);
• the torque wrench is used to tighten the nuts securing the axles of the upper and then the lower levers, and the nuts securing the axle of the lower lever to the crossmember. Then the wheel alignment angles are checked and adjusted.
