• Q: How to Replace the Crankshaft Seal in a Vehicle on 2003 Toyota Matrix?

  A: Following the replacement of the crankshaft main bearing seal requires the manual transaxle assembly removal along with the automatic transaxle assembly for both 2WD and 4WD drive types. Proper installation of the transaxle assembly occurs only after detaching the engine assembly with transaxle. The manual transaxle requires removal of the clutch cover assembly followed by the clutch disc assembly and the flywheel sub-assembly. The 8 bolts and flywheel need removal with Special Service Tool: 09960-10010 (09962-01000, 09963-01000) to fix the crankshaft. To remove the components from the automatic transaxle use a special service tool for detaching the eight bolts from the drive plate and ring gear sub-assembly. The first step involves cutting off the oil seal lip which enables the removal of the seal using a screwdriver. Check the crankshaft after removal because damaged parts need sandpaper (#400) for repair. Use Special Service Tool: 09223-15020, 09950-70010 (09951-07100) to insert the new engine rear oil seal by taping it into the retainer edge until flush and wiping off excess grease. Before sequencing apply MP grease to the lip while inspecting it for foreign materials. The installation of the flywheel sub-assembly requires fixing the crankshaft with Special Service Tool: 09960-10010 (09962-01000, 09963-01000) while cleaning the bolts and bolt holes then applying adhesive (Part No. 09330-00070, Three Bond or equivalent) to the bolts before uniformly tightening the 8 bolts in sequence to 49 Nm (500 kgf-cm, 36 ft. lbs.) torque and marking bolts with paint then retightening by an additional 90 plus or minus. Check that all marked bolts show proper movement at a right angle position. After installing the clutch disc assembly and clutch cover assembly for the manual transaxle you must perform the same sequence with the drive plate and ring gear sub-assembly for the automatic transaxle by using Special Service Tool: 09960-10010 (09962-01000, 09963-01000) to clean bolts before applying adhesive (Part No. 09330-00070, Three Bond or equivalent) followed by uniform bolt tightening to 88 Nm (897 kgf-cm, 65 ft. lbs.). Completion of manual transaxle assembly installation concludes the procedure while automatic transaxle assemblies should be installed for both 2WD and 4WD drive types.
