Fig. 4.5. Ground clearance measurement points
Measuring the vehicle's ground clearance is necessary to ensure the accuracy of the wheel alignment angles, as these angles vary slightly depending on the vehicle's height. The points for measuring ground clearance are shown in Figure 4.5.
The R1 dimension is measured between the floor and the front wheel pivot point.
The R2 dimension is measured between the floor and the rear wheel pivot point.
Fig. 4.6. Dimension W1 between the floor and the lower end of the head of the bolt for fastening the rear cross member of the subframe
The dimension W1 is measured between the floor and the lower end of the head of the bolt securing the rear cross member of the subframe (Fig. 4.6).
Fig. 4.7. Dimension W2 between the floor and the axis of the silent block attachment on the support
The dimension W2 is measured between the floor and the axis of the silent block attachment to the support (Fig. 4.7).
