Axle Assembly, Driver Side

Starting front drive shaft disassembly requires users to remove the No. 2 axle inboard joint boot clamp either with screwdriver or needle-nose pliers based on the clamp type. You need to remove the front axle inboard joint boot clamp by using the same method. The inboard joint boot must be uninstalled from the inboard joint assembly before cleaning the inboard joint with old grease debris. Make match marks on the inboard and outboard joint shaft assembly while avoiding punched marks and separate the inboard joint from the outboard joint shaft. A snap ring expander extraction tool should remove the shaft snap ring before applying matchmarks to both the outboard joint shaft and tripod joint without punching the marks. A brass bar with a hammer should be used to carefully remove the tripod joint from the outboard joint shaft while avoiding the rollers before finally taking off the inboard joint boot. You need a screwdriver if your front drive shaft damper has a one-touch clamp but needle-nose pliers work for the claw engagement type to detach the clamp before pulling out the front drive shaft damper. Start by utilizing a screwdriver to remove the one-touch type outboard joint boot clamp from the No. 2 axle and proceed with removing the front axle outboard joint boot clamp in the same fashion. Take off the outboard joint boot from the outboard joint shaft then wipe away all old grease from the joint. Use the screwdriver to remove the front drive shaft hole snap ring while Special Service Tool: 09950-00020 and a press extract the front drive shaft dust cover from the LH side keeping the inboard joint assembly safe from dropping before repeating the process on the RH side. Press the drive shaft bearing case out using a press after removing its sub-assembly snap ring with a screwdriver and avoid letting the inboard joint assembly fall. Also extract the straight pin. Using Special Service Tool 09950-00020 press the front drive shaft dust cover to completion while keeping the inboard joint assembly protected from falling. Then extract the drive shaft bearing by first applying a snap ring expander to remove the drive shaft hole snap ring before using Service Tool 09527-10011 and a press to push out the bearing then discarding the snap ring.

The first step for axle shaft assembly replacement requires draining both automatic transaxle fluid and manual transaxle oil. The front wheel and engine under cover needs to be removed first before using Special Service Tool: 09930-00010 and a hammer to unstake the front axle hub nut. The nut must be fully loosened to protect the drive shaft screw from damage. The front stabilizer link assembly requires removing its nut before checking if the ball joint rotates. Use a 6 mm hexagon wrench to maintain the stud position in place. Pull off the front speed sensor by disconnecting its wire and flexible hose attached to the shock absorber then to the steering knuckle while being careful not to damage the components. The disconnect process requires removal of the cotter pin along with the nut from the tie rod end sub-assembly for subsequent use of Special Service Tool: 09628-00011 to separate the sub-assembly from the steering knuckle. To perform the front No. 1 suspension lower arm sub-assembly removal you must first uninstall the bolt and two nuts. The procedure to remove the front axle assembly starts with marking both the drive shaft and axle hub before separating them using a plastic-faced hammer while protecting the boot and speed sensor rotor. Special Service Tools: 09520-01010, 09520-24010, and 09520-32040 remove the front drive shaft assembly LH while protecting the transaxle case oil seal alongside the inboard joint boot and drive shaft dust cover from damage. To access the drive shaft bearing case of the RH front assembly remove its two retaining bolts then carefully extract the drive shaft keeping safety in mind of inboard joint boot damage or dust cover wear. It is appropriate to add vehicle weight to hub bearings using Special Service Tools: 09608-16042, 09608-02021, or 09608-02041 but keep the tools as safety mechanisms to avoid damage.

Install the dust covers ensuring they are not damaged, and install the outboard joint boot and clamps, packing with grease.

Align the matchmarks and install the drive shaft to the front axle, taking care not to damage the outboard joint boot and speed sensor rotor.

Remove the inboard joint boot clamps and the inboard joint boot, clean the inboard joint, and carefully remove the inboard joint assembly and dust covers using Special Service Tool: 09950-00020 and a press.

Use Special Service Tool: 09520-01010, 09520-24010, and 09520-32040.

Use Special Service Tool: 09930-00010 and a hammer to unstake the nut, ensuring it is completely loosened to avoid damaging the drive shaft screw.

Begin by draining the automatic transaxle fluid and manual transaxle oil.
