DIFFERENTIAL M t- 900mm (35.43 in) 10. Remove the transmission-side bolts, and remove the PPF. Do not remove the spacers from the PPF. If they are removed, replace the PPF as an assembly. Drive shaft Mark the drive shaft and output shaft for proper installa- tion. Differential 1. Support the differential with a jack. 2. Lower the differential and move it forward. Note If the drive shaft will not separate easily from the out- put shaft, remove a bolt and nut from one side of the upper arm. 3. Separate the driveshaft from the output shaft. 4. To prevent damaging the fire wall, crank angle sensor, and engine mount, support the transmission as follows. (1) Prepare a steel plate (as shown in the figure), a wooden block, bolts (M8 x 1.25), and washers. (2) Install the parts as shown in the figure. Gartner Banana
