• Q: How to service and repair the axle shaft assembly on 2007 Toyota Sienna?

  A: Service for the front drive shaft assembly starts when you drain automatic transaxle fluid using the drain plug procedure followed by gasket installation before tightening the drain plug to 49 Nm (500 kgf-cm, 36 ft. lbs.). The process of draining transfer oil should be performed on all 4WD vehicles. The front wheel along with both nut components from the front axle hub must be removed with Special Service Tool: 09930-00010 and a hammer to unstake and fully loosen the nut before removing it to prevent drive shaft screw damage. Apply brake pressure during which time you can take out the lock axle hub LH nut. After removing the nut from the front stabilizer link assembly LH you should check whether the ball joint turns. If it does turn apply a 6 mm hexagon wrench to maintain the stud stable. First detach the front LH speed sensor bolt while unwiring the clip after checking for any component damage before splitting the tie rod end sub-assembly LH with Special Service Tool: 09628-62011. Separate the No. 1 front suspension arm sub-assembly lower LH by unfastening its bolt followed by two nuts. A plastic hammer allows you to separate the front axle assembly LH from the drive shaft but you should avoid damaging the boot and speed sensor rotor. Seize the front drive shaft assembly LH using Special Service Tools 09520-01010 and 09520-24010 (09520-32040) to ensure no damage happens to the transaxle case oil seal inboard joint boot and drive shaft dust cover. After removing the bearing brake hole snap ring with the bolt, you can take out the front drive shaft assembly RH on 2WD vehicles. The same tools will be used for 4WD front drive shaft disassembly steps while draining all transaxle and transfer oil before installation to prevent oil mixture. The front axle assembly needs to be secured for protection of the hub bearing from harm. The No. 2 front axle inboard joint boot LH clamp and the front axle inboard joint boot LH clamp must be removed along with the inboard joint boot separation from the inboard joint assembly. Separate the front drive inboard joint assembly LH before marking the outboard joint shaft and inboard joint shaft with a punch avoiding usage. Use a brass bar and hammer to eliminate the snap ring and tripod from the outboard joint shaft while protecting the roller from damage. Next proceed with taking off the front drive shaft damper clamp and the damper component followed by both outboard joint boot clamps and their related boots. Use Special Service Tool: 09950-00020 to remove the LH hole snap ring along with the dust covers from the front drive shaft assembly through a press operation while preventing inboard joint assembly drops. Follow these steps to rebuild the front drive shaft assembly LH through proper inspection then reinstallation of the front drive shaft bearing using Special Service Tool: 09710-30021 (09710-03141). Complete the assembly process with the reinstallation of the RH hole snap ring and dust covers. After installing the outboard joint boot along with its clamps you need to pack it with grease then you can mount the drive shaft damper by retaining a preset distance. The inboard joint assembly needs to be installed with matchmark alignment before tightening the boot clamps. First apply ATF to the inboard joint shaft assembly spline then align the splines before installing the drive shaft assembly at a flat position. The installation of the RH front drive shaft assembly should proceed identically to the LH side but must prevent any damage from happening. Reinstall the front axle assembly LH then install the No. 1 front suspension arm sub-assembly lower LH together with the tie rod end sub-assembly LH by applying correct torque specifications. Replace the speed sensor front LH after securing the stabilizer link assembly LH as well as the axle hub LH nut and stake it for protection. After installation of the front wheel complete the procedure by adding automatic transaxle fluid and transfer oil for 4WD while inspecting front wheel alignment and checking the ABS speed sensor signal.
