Disassembly Procedure

1.  Perform the following inspection:

Caution
•  If there is no malfunction based on the results of the inspection, it not necessary to disassemble the ring gear and differential.
•  Visual inspection of parts (See VISUAL INSPECTION OF PARTS [FW6A-EL/FW6AX-EL])
•  Ring gear and differential inspection (See RING GEAR AND DIFFERENTIAL INSPECTION [FW6A-EL/FW6AX-EL])
•  If there is a malfunction, disassemble the ring gear and differential and replace the malfunctioning part with a new part.

2.  Remove the taper roller bearing (transaxle case side) using the following procedure:

(1)  Secure the ring gear and differential in a vise.
