Vacuum Actuator Problems
The colder the temperature, the longer it will take to engage.
If the front differential becomes submerged, the TLA temperature will cool and the 4-wheel drive will disengage.
The TLA unit can cause excessive wear on internal components in the differential and may cause other electrical problems.
