^ Check the driveshaft spline part for wear or damage.
^ Check the inner shaft spline part for wear or damage.
^ Check the spider assembly for roller rotation, wear or corrosion.
^ Check the groove inside TJ case or PTJ case for wear or corrosion.
^ Check the boots for deterioration, damage or cracking.
^ Check the center bearing for seizure, discoloration or roughness of rolling surface.
^ Check the dust cover for damage or deterioration.
BJ/EBJ BOOT REPLACEMENT
Required Special Tool:
MB991561: Boot Band Crimping Tool
1. Remove the boot bands (large and small).
NOTE: The boot bands cannot be re-used.
2. Remove the BJ/EBJ boot.
3. Wrap a plastic tape around the shaft spline, and assemble the boot band and BJ/EBJ boot.
4. Align the center groove on the BJ/EBJ boot small end with the shaft groove.
5. Turn the adjusting bolt on special tool MB991561 so that the size of the opening (W) is at the standard value.
Standard value (W): 2.9 mm (0.11 inch)
[If it is larger than 2.9 mm (0.11 inch)] Tighten the adjusting bolt.
[If it is smaller than 2.9 mm (0.11 inch)] Loosen the adjusting bolt.
NOTE: The value of W will change by approximately 0.7 mm (0.03 inch) for each turn of the adjusting bolt.
NOTE: The adjusting bolt should not be turned more than once.
6. Position the BJ/EBJ boot band (small) so that there is even clearance at either end (A and B).
CAUTION
^ Secure the driveshaft in an upright position and clamp part of the boot band to be crimped securely in the jaws of special tool MB991561.
^ Crimp the boot band until the special tool touches the stopper.
7. Use special tool MB991561 to crimp the boot band (small).
8. Check that the crimping amount (C) of the boot band is at the standard value.
Standard value (D): 2.4 - 2.8 mm (0.09 - 0.11 inch)
[If the crimping amount is larger than 2.8 mm (0.11 inch)]
Readjust the value of (W) in step 5 according to the following formula, and then repeat the operation in step 7.
W = 5.5 mm (0.22 inch) - D
Example: If D = 2.9 mm (0.11 inch), then W = 2.6 mm (0.10 inch).
[If the crimping amount is smaller than 2.4 mm (0.09 inch)]
Remove the BJ/EBJ boot band, readjust the value of (W) in step 5 according to the following formula, and then repeat the operations in steps 6 and 7 using a new BJ/EBJ boot band.
W = 5.5 mm (0.22 inch) - D
Example: If D = 2.3 mm (0.09 inch), then W = 3.2 mm (0.13 inch).
9. Check that the boot band does not stick out past the place where it has been installed. If the boot band sticks out, remove it and then repeat steps 6 to 8, using a new boot band.
CAUTION
The driveshaft joint uses special grease. Do not mix old and new or different types of grease.
10. Fill the inside of the boot with the specified amount of the specified grease.
Specified grease: Repair kit grease
Amount to use (BJ) [2.4L]: 120 ± 10 g (4.2 ± 0.3 ounces)
Amount to use (BJ) [3.8L (Except MIVEC)]: 165 ± 10 g (5.8 ± 0.3 ounces)
Amount to use (EBJ) [3.8L (MIVEC)]: 155 ± 10 g (5.5 ± 0.3 ounces)
11. Align the center groove on the BJ/EBJ boot big end with the BJ/EBJ case groove.
12. Follow the same procedure as in step 5 to adjust the size of the opening (W) on special tool so that it is at the standard value.
Standard value (W): 2.9 mm (0.11 inch)
13. Position the BJ/EBJ boot band (large) so that there is even clearance at either end (D and E).
14. Use special tool to crimp the BJ/EBJ boot band (large) in the same way as in step 7.
15. Check that the crimping amount (F) of the boot band is at the standard value.
Standard value (F): 2.4 - 2.8 mm (0.09 - 0.11 inch)
[If the crimping amount is larger than 2.8 mm (0.11 inch)]
Readjust the value of (W) in step 12 according to the following formula, and then repeat the operation in step 14.
W = 5.8 mm (0.23 inch) - F
Example: If F = 2.9 mm (0.11 inch), then W = 2.9 mm (0.11 inch).
[If the crimping amount is smaller than 2.4 mm (0.09 inch)]
Remove the EBJ/EBJ boot band, readjust the value of (W) in step 12 according to the following formula, and then repeat the operations in steps 13 and 14 using a new EBJ/EBJ boot band.
W = 5.8 mm (0.23 inch) - F
Example: If F = 2.3 mm (0.09 inch), then W = 3.5 mm (0.14 inch).
16. Check that the boot band does not stick out past the place where it has been installed. If the boot band sticks out, remove it and then repeat steps 13 to 15, using a new boot band.
