Total Backlash Check

If the vehicle vibrates and produces a booming sound due to an imbalance of the driving system, measure the rear axle total backlash by the following procedures to see if the differential carrier assembly requires removal.
1) Place the gearshift lever in the neutral position, apply the parking brake and jack up the vehicle.





2) Manually turn the propeller shaft clockwise as far as it goes and make mating marks on the companion flange dust shield and the differential carrier.





3) Manually turn the propeller shaft counterclockwise as far as it goes and measure the movement of the mating marks.

Limit: 5 mm (0.2 inch)

4) If the backlash exceeds the limit, remove the differential carrier assembly and adjust the backlash.
