Removing inner ring/tapered-roller bearing –  Fit thrust plate -MP3-467 (40 - 105)- on drive wheel.

Press on inner ring/tapered-roller bearing   Note A pressure plate must be placed under the hub of the drive wheel to avoid damages to the drive wheel.

Inser inner ring/tapered-roller bearing –  Before inserting, coat the area of the bearing seat -arrow- of the inner rings successively with locking agent -AMV 185 101 A1-. On inner rings with “pegs”, the “pegs” must grip into each other. –  Then successively install the inner rings.

Remove drive wheel –  Position pressing tool -MP3-428 (40 - 503)- with collar into the threaded bore of the drive wheel. –  Fit washer -A- and connect with multi-purpose tool -MP3-419 (VW 771)-. –  Carefully drive out drive wheel with multi-purpose tool -MP3-419 (VW 771)-. –  Remove multi-purpose tool -MP3-419 (VW 771)- and take out drive wheel.

Remove and install tensioning screw –  Engage parking position for slackening and tightening. A -  Torque wrench B -  Socket wrench insert waf 22
