W126_Rubber Boot_drive shaft center support bearing

MARK THE DRIVE SHAFT FOR RE-ASSEMBLY, BEFORE SEPARATING THE SLIP JOINT...

This rubber carrier boot can be replaced without disturbing the bearing.

I use a small pry bar against the boot edge, and tap it off/on with a small ball peen hammer.

NOTE:
Clean and lubricate the slip joint splines with axle grease before assembly..

Im in the process of this very job however I cannot get the bearing to seat all the way down in the rubber bushing. Ive tried soapy water and a little persuasion with a wood block and mallet but it wont seat all the way in. Suggestions?
