t  Counterhold tool -T10172- with adapters -T10172/5- Removing   Note t  Repairs on the propshaft should preferably be carried out on a two-pillar hoist. t  Before removing, mark the positions of all parts in relation to each other. Reinstall in the same position to avoid excessive imbalance, resulting in bearing damage and rumbling noise. t  Do not bend propshaft; only store and transport fully extended. t  Always support the propshaft during removal; it must not be suspended from one of the joints. t  Always keep the propshaft horizontal while pulling it off or fitting it on the joint flange.

–  Remove noise insulation -1- → Rep. gr.66.

–  Remove bolts -arrows- and detach cross piece -1-. –  Remove heat shield for centre tunnel → Rep. gr.66.

–  Slacken bolts -arrows- for centre bearing 2 turns.

–  Check whether there is a factory marking (paint dot) on the flexible coupling and on the flange for the propshaft on the rear final drive -arrows-. –  If there is no marking, mark position of flexible coupling relative to flange for propshaft on rear final drive. –  Also mark position of propshaft in relation to bevel box flange.

–  When loosening propshaft bolts, counterhold at rear final drive using counterhold tool -T10172- and adapters -T10172/5-. –  Loosen front and rear propshaft bolts but do not remove them yet.

–  Detach bolts -arrows- securing propshaft to rear final drive. –  Support propshaft with engine and gearbox jack -V.A.G 1383 A-.

–  Remove bolts -arrows- securing centre bearing and take out propshaft towards rear. Installing Installation is carried out in reverse sequence; note the following: l  Tightening torques → Chapter   Note Install all parts in the same relative positions, as marked before removal.

–  Attach propshaft to rear final drive so that the markings -arrows- align.

–  Fit bolts -arrows- for centre bearing, but do not tighten yet. –  Tighten bolts securing propshaft flexible coupling to bevel box and rear final drive. –  Align centre bearing within elongated holes so that neither propshaft nor centre bearing are under stress. –  Tighten bolts -arrows-. –  Install heat shield for centre tunnel → Rep. gr.66. –  Install pendulum support → Rep. gr.34. –  Install rear section of exhaust system → Rep. gr.26. –  Install cross piece and noise insulation → Rep. gr.66.
