Elements of a suspension bracket of forward wheels
The four-lever, independent suspension bracket of forward wheels has depreciation racks of McPherson and the torsion stabilizer of cross stability.
Depreciation racks consist of cylindrical screw springs, shock-absorbers in the form of a double pipe and the top support of the big size. The stabilizer does not participate in the direction of wheels, and through connecting bars is connected with depreciation racks.
The depreciation rack is fixed by bolts to a support of the top lever and to the forward cross lever.

At the wrong wear of tires, and also at insufficient stability on the road it is necessary to perform optical measurements and, if necessary, to adjust corners of installation of wheels.
