The front suspension
Design and specifications Independent front suspension with telescopic shock absorbers with helical coil springs, upper and lower arms and stabilizer bar connecting the upper suspension arms. All mounts suspension made on silent blocks (rubber bushing). Stub is connected to the suspension arms through sealed ball joints (ball studs). The hub of the front wheel is adjustable tapered bearings. Characteristic | Value | Wheel bearing axial play mm | 0.01-0.02 |
Coil springs
Depending on the model and equipment installed on the vehicles of several types of coil springs in combination with the upper bearing cups of different thicknesses.

Selection of spring suspension with upper bearing cup
For vehicles used in the front suspension springs and support plates of four types. Selection of spring and bearing cups at the factory and must be maintained throughout the lifetime of avoiding deterioration of the stability and controllability of the car. When replacing the spring or bearing cups sure to install parts that are identical to the former. Spring to the support dish chosen by the sum of points. This amount consists of the score models and points of additional equipment.
