LIMITED SLIP DIFFERENTIAL
Traction-Lok™ and TORSEN™
Axles
These axles provide improved traction on
slippery and loose surfaces, particularly
when one wheel is on a poor traction
surface. Under normal conditions, these
axles function like a standard rear axle.
Extended use of tire sizes other than the
manufacturer’s specified tire size on these
axles could result in a permanent reduction
in effectiveness. This loss does not affect
your normal driving and should not be
noticeable.

Use fluid that meets the defined
specification and viscosity grade.
If you do not use fluid that meets the
defined specification and viscosity grade,
it could result in:
• Component damage that your vehicle
warranty does not cover.
