Final Drive

Due to their function, the shafts of the right and left stub axles in the final drive have different lengths. In an idle state, this results in a noticeable different vertical clearance of both flanges, which is a feature of the design.

This does not affect the function and is not a cause for complaint.

This uneven clearance applies for all models with fully variable M slip differential and may affect either the right or the left flange, depending on the version and model.
