5	Remove differential pressure sensor.	Model 257 with engine 264 with code 598 (Gasoline particulate filter (OPF) with sensor system)
			AR07.04-P-0025MRH
6	Remove all heat shields under propeller shaft (1).
7	Remove front reinforcement (2).	Bolt, reinforcement under seat to frame floor assembly	*BA61.10-P-1005-01L
8	Remove center reinforcement (3).	Bolt, center reinforcement to frame floor assembly	*BA61.10-P-1003-01L
9	Mark propeller shaft (1).	In order to be able to reproduce the factory installation position when installing, apply a color marking identifying the position of the propeller shaft (1) relative to the flanges on the transmission and rear-axle differential.
10	Mark propeller shaft intermediate bearing (5).	In order to be able to reproduce the factory installation position when installing, make colored markings of the position of the propeller shaft intermediate bearing (5) relative to the frame floor assembly. Observe marking.
11	Loosen screws on propeller shaft intermediate bearing (5).	Tighten screws securely only after the propeller shaft (1) has been securely fitted to the transmission and rear axle differential.

13	Remove screws from propeller shaft intermediate bearing (5) and guide out propeller shaft (1) towards the rear.	Screw in screws loosely and tighten only after the flex disks (6) have been tightened at the transmission and rear axle differential. Vibrations in the drive train and damage may otherwise occur. Make sure that the propeller shaft halves do not come apart at the slide joints. Otherwise damage will occur.
	Check
14	Check propeller shaft intermediate bearing (5) for wear and damage.	If problems exist, ↓ replace propeller shaft intermediate bearing (5).
			AR41.10-P-0100MSA
15	Check pilot bushings for wear and damage.	If problems exist, ↓ Replace pilot bushings.
			AR41.10-P-0250MSA
16	Check flex disks (6) for wear and damage.
			AP41.10-P-4152EW
		If problems exist, ↓ replace respective flex disk (6).
17	Install in the reverse order.
