* Glass ∅ 48 mm with a beveled bottom, in which a radial groove 17 mm wide is made. A screw M22x1.5 is screwed into the glass.
Insert screw 2 (Fig. 161) of device 67.7828.9504 (Fig. 162) into the hole of the upper support of the suspension spring, put it on the spring coil 3 from below (see fig. 161) and screw 2 support plate 1 and secure it to the spring with a clamp. Screw a nut onto the screw from below so that its lock fits into the socket of plate 1. Turn screw 2 with a wrench to compress the spring until the suspension arms are completely unloaded. Remove the upper arm axle and disconnect it from the body. Disconnect the lower arm axle from the crossmember and remove the vehicle suspension unit. In doing so, it is necessary to mark the number and location of the washers between the lower arm axle and the crossmember, as well as the adjusting plates between the crossmember and the body side member, 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.
The main element of the 67.7828.9504 device is the support plate 1. It is made in the form of a disk with a central hole with a diameter of 27 mm, on the side of which a socket for a nut lock is sawn. A support surface for a spring coil is made on the disk, according to the shape and size of the spring support of the lower suspension arm. A handle with a threaded hole M8x1.25 is welded to the side of the disk, to which the clamp bar for fastening the plate on the spring coil is screwed.
Remove the mudguard and stabilizer bar. Supporting the engine with a crossmember A.70526 or a hoist, remove the suspension with the crossmember as an assembly.
Install the suspension units and parts in the reverse order of removal. In this case, install only group A springs on the front suspension (marked with yellow paint).
To prevent incorrect distribution of forces in the rubber-metal hinges, tighten the nuts and axles of the levers in the following order:
- place the car on a level surface and point the wheels straight ahead;
- load the car with a mass of 320 kg (4 people + 40 kg in the trunk).
Using a torque wrench, tighten the nuts securing the axles of the upper and then the lower control arm, and the nuts securing the axle of the lower control arm to the crossmember. Then check and adjust the wheel alignment angles.
