LIMITED-SLI P REAR AXLE
The optional limited-slip rear axle on vehicles that have it, can give
added traction on snow, ice, mud, sand, gravel, etc. Normally, the
limited-slip axle unit works like a standard axle. However, when either

continue to give driving force to the wheel having the greater traction,
instead of merely spinning the wheel that has the least traction.
