Remove the front lower arm from the front knuckle using the SST (0K545-A9100).

(1)	After removing bolts from the front knuckle, install and tighten the sub body bolt (A) .

(2)	Input the sub body (A) between the front knuckle and the sub body bolt.

(3)	Tighten bolt (B) of the sub body bolt to broaden the gap of the front knuckle.

(4)

Install the safe wire (A).

Install a safe wire on the front strut to prevent dropping the SST and hurting technicians.

(5)	Install the main body, between the front strut and the lower arm.

(6)	To avoid the main body coming off, install a fixing clamp (A) beside the main body.

(7)	After installing a fixing clamp, rotate the handle (B) clock wise till the clamp is fixed on a lower arm.

(8)	Tighten a main body bolt (A) of the slowly and remove the lower arm from the front knuckle.

10.	Disconnect the driveshaft (A) from the front hub assembly.

11.	Remove the driveshaft cover (A).

12.	Loosen the mounting bolts and then remove the inner shaft (A) & driveshaft assembly (B).

13.	Disconnect the driveshaft (A) from inner shaft (B).

14.

Install in the reverse order of removal.

•	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.

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 (UTJ) case.

3.	Pull out the boot from transaxle side joint case (B).

While dividing joint (UTJ) boot (A) of the transaxle side, wipe the grease in UTJ case (B) and collect them respectively.

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

5.	Remove the snap ring (A) and spider roller assembly (B) from the shaft.

6.	Clean the spider assembly.

Remove the boot (A) of the transaxle side joint (UTJ).

For reusing the boot (A), wrap tape (B) around the driveshaft splines (C) to protect the boot (A).

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

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

10.	Apply soap powder on the shaft to prevent being damaged between the shaft spline and the dynamic damper when the dynamic damper is removed.

11.	Saperate the dynamic damper (A) from the shaft (B) carefully.

Reassembly

1.	Wrap tape around the driveshaft spline (UTJ) to prevent damage to the boots.

2.	Apply grease to the joint boot on the side of the wheel and install the boot.

3.	Install the clamp.

4.	To install the dynamic damper (A), keep the shaft in a straight line and assemble the dynamic damper with the bands (B).

5.	Assemble the transaxle side joint boot and bands.

6.	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).

7.	Add specified grease to the joint boot as much as it was wiped away at inspection.

8.	Install the both boot band.

To control the air in the UTJ boot, keep the specified distance between the boot bands when they are tightened.

Items	Distance (L) mm(in)
Items	LH side	RH side
Lambda 3.3 GDI	517.8 (20.39)	531.5 (20.93)

10.	Using the SST (09495-3K000), secure the UTJ boot bands.
