Most German vehicles these days utilize limited slip differentials for improving traction on slippery roads. It’s precisely for this reason that you need to bring your vehicle to an Audi and VW service for tire replacement and alignment.
Limited Slip Differentials (LSD) Explained
Most American cars, especially older models, use a standard differential where the left and right axle rotations are completely independent of each other. This creates a problem when one wheel comes across a slippery surface. This causes the wheel to spin excessively while the other continues to spin at normal speeds. This causes more power to flow to the slippery wheel while power flow comes to a near halt for the other. This can result in significant shifting problems or even bring the vehicle to a halt.
A limited slip differential seeks to address this problem by reducing the independency between the two axles. Most LSDs use a clutch pack based system. It’s not necessary to understand the exact mechanics of how the system works; all you need to know is that the component includes friction and steel plates wedged between the casing and side gear. This enables for a distribution of power so that one wheel absorbs a portion of the traction loss should the other wheel come upon a slippery surface.

Bring Your German Vehicle to Buttera Motors
Since most German vehicles uses a LSD, any Audi and VW repairs to the tires or axle require special attention. It’s also absolutely important that new tires match the one being replaced exactly. Even as little as a 2cm circumference difference can cause rotational speed variances that can create premature wear on the drive train management system present in most modern Audis and Volkswagens.
