Frequently asked questions

What does the 571957 vacuum actuator do?
This vacuum actuator engages the centre differential lock on the LT95 four-speed gearbox. Manifold vacuum moves the actuator piston, which shifts the diff-lock selector fork to couple the front and rear output drives.
Where is the vacuum actuator located?
It mounts on the selector fork housing at the front output of the LT95 gearbox, fitted to V8 manual applications.
Why would this vacuum actuator fail?
Vacuum actuators typically fail from a split diaphragm or a perished vacuum hose, both of which stop the piston moving and leave the centre diff unable to lock or unlock properly. A hissing sound near the gearbox often points to this.
