REMOVAL SERVICE POINTS

.

<<A>> DRIVE SHAFT NUT REMOVAL

CAUTION

Do not apply pressure to the wheel bearing by the vehicle 
weight to avoid possible damage when the drive shaft nut 
is loosened.
Use special tool MB990767 to fix the hub and remove the drive 
shaft nut.

.

<<B>> TIE ROD END CONNECTION/LOWER ARM 
BALL JOINT CONNECTION REMOVAL

CAUTION

• Do not remove the nut from ball joint. Loosen it and use 

the special tool to avoid possible damage to ball joint 
threads.

• Hang the special tool with cord to prevent it from fall-

ing. 

1. Replace the self locking nut with a regular nut, because the 

original one is a little bit large to install the special tool. 
Install special tool MB991897 as shown in the figure.

<<C>> DRIVE SHAFT <LH>/DRIVE SHAFT AND 
INNER SHAFT ASSEMBLY <RH> REMOVAL

1. Use special tools MB990242, MB990244, MB991354 and 

MB990767 to push out the drive shaft or the drive shaft and 
inner shaft assembly from the hub.

2. Remove the drive shaft from the hub by pulling the bottom of 

the brake disc towards you.

CAUTION

• Do not pull on the drive shaft; doing so will damage the 

PTJ; be sure to use the pry bar.

• When pulling the drive shaft out from the transmission, 

be careful that the spline part of the drive shaft does 
not damage the oil seal.

3. Insert a pry bar between the transmission case and the drive 

shaft, and then pry and remove the drive shaft from the 
transmission.
