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.
Disassembly
   
   
Do not disassemble the BJ assembly.
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 circlip (B) from the driveshaft spline (A).


2.
Remove both boot bands from the transaxle side joint(TJ) case.


3.
Pull out the boot from transaxle side joint case (B).
4.
While dividing joint(TJ) boot (A) of the transaxle side, wipe the grease in TJ case (B) and collect them respectively.

Remove the boot (A) of the transaxle side joint(TJ).
   
   
For reusing the boot (A), wrap tape (B) around the driveshaft splines (C) to protect the boot (A).


9.
Using a plier or flat-tipped (-) screwdriver, remove the both side of clamp (B) of the dynamic damper (A).


10.
Fix the driveshaft (A) with a vice (B) as illustrated.


11.
Apply soap powder on the shaft to prevent being damaged between the shaft spline and the dynamic damper when the dynamic damper is removed.
12.
Saperate the dynamic damper (A) from the shaft (B) carefully.


13.
Using a plier or flat-tipped (-) screwdriver, remove the BJ boot band on the side of wheel.
