Remove the rear differential. Rear Differential (T-type) > REMOVAL Rear Differential (VA-type) > REMOVAL 2. Fit the ST to the periphery of the sub frame cylinder, and make sure that the ST does not contact with welded spots or spatters.
3. If the ST contacts with welded spots or spatters, remove the excessive welds or spatters with sander or the equivalent so that the ST contacts the cylinder peripheral part. CAUTION: Performing the operation with the ST contacting with welded spots or spatters may break the ST. Be sure to remove excessive welds or spatters before the operation. 4. Set ST1, ST2, ST3, ST4 and ST5 as shown in the figure.
5. Fit and hold the ST1 and ST2 to the rear differential mount bushing from the rear side of vehicle.
6. Insert the ST set in the step 4) through the rear differential mount bushing hole from the front side of vehicle, and screw in the ST1 by hand till the front end of ST1 comes out slightly from the rear end of ST2.
7. Hold the ST1 to prevent it from rotating, and screw in the ST3 by hand till there is no loose fit on the ST2. CAUTION: When setting the ST to the vehicle, always make sure that the ST2 fits the periphery of the sub frame cylinder and is not tilted.
8. Hold the ST1 with a tool to prevent it from rotating, and screw in the ST2 to remove the rear differential mount bushing. CAUTION: • Rotation of ST1 will damage the screw at the rear end of rear differential mount bushing. Never rotate the ST1. • If the ST starts to tilt while removing the rear differential mount bushing, stop the work and set the ST again.
9. Set ST1, ST2, ST3, ST4, ST5 and rear differential mount bushing as shown in the figure. NOTE: • Set the ST2 nut near to the end of ST1 screw. • Hold the rear differential mount bushing with the marked side facing toward the rear of the vehicle, and set the rear differential mount bushing to the ST so that the arrow mark faces upward. • Mark the bottom end of rear differential mount bushing to identify the installing direction.
10. Attach ST1 to the ST2, and fit and hold the STs as a unit to the sub frame from the rear side of vehicle.

13. Screw in the ST2 while holding the ST1 with a tool to prevent it from rotating, and press-fit the rear differential mount bushing to the front end of sub frame cylinder.
14. Make sure that the rear differential mount bushing is inserted to the front end of sub frame cylinder.
