you encounter. Maximum axle temperature may
vary, depending upon the axle and type of lubricant. Very
high temperatures signal a need to have your axle(s) lubrication
checked.
CAUTION: Driving with very hot temperatures in
your rear drive axles can cause serious damage
to axle bearings and seals. Have your axle lubrication
checked if you notice a sign of overheating.
