[LH]

  
• Use a pry bar (A) being careful not to damage the transaxle and joint.
• Do not insert the pry bar (A) too deep, as this may cause damage to the oil seal.
• Do not pull the driveshaft by excessive force it may cause components inside the joint kit to dislodge resulting in a torn boot or a damaged bearing.
• Plug the hole of the transaxle case with the oil seal cap to prevent contamination.
• Support the driveshaft properly.
• Replace the retainer ring whenever the driveshaft is removed from the transaxle case.
9. To install, reverse the removal procedure.
10. Check the front alignment.

TJ Joint Repair procedures

Disassembly
  
• Special grease must be applied to the driveshaft joint. Do not substitute with another type of grease.
• The boot band should be replaced with a new one.
1. Remove the Front Driveshaft.

(Refer to Driveshaft Assembly - "Front Driveshaft")
2. Remove the housing circlip (B) from the driveshaft spline (A).
3. Remove both boot bands from the TJ housing.
4. Remove the TJ housing (A).

  
• Make alignment marks on spider roller assembly (A), joint case (B), and shaft spline (C) to aid reassembly.

5. Remove the snap ring (A) from the shaft.
6. Remove the spider assembly (B) from the driveshaft (A) using the special tool SST (09495-33000).
7. Clean the spider assembly.
8. Remove the TJ boot (A).
  
• For reusing the boot (A), wrap tape (B) around the driveshaft splines (C) to protect the boot (A).

Inspection
1. Check the driveshaft boots for damage and deterioration.
2. Check the driveshaft spline for wear or damage.
3. Check that there is no water or foreign material in the joint.
4. Check the spider assembly for roller rotation, wear or corrosion.
5. Check the groove inside the joint case for wear or corrosion.
6. Check the dynamic damper for damage or cracks.
Reassembly
1. Wrap tape around the driveshaft spline(TJ) to prevent damage to the boot.
2. Using the alignment marks (D) made during disassembly as a guide, install the spider assembly (A) and snap ring (B) on the driveshaft splines (C).
3. Add specified grease to the joint boot as much as it was wiped away at inspection.
4. Install the both boot band.
