Removal:

–  Place the support bracket -10-222 A- with the adapters -10-222/3- on the screw joint edges of the mudguard. –  Remove wheels.

–  Loosen the quick locks-1 … 3- and remove the front and rear noise damping.

–  Thread off the bracket of the noise damping -arrow-.

–  Before loosening the subframe, use locating pins - 3393- to check whether holes -1- and -2- are aligned. If this is not the case, wheel alignment has to be performed after installing the subframe. –  Remove anti-roll bar → Chapter.

–  Thread off the fastening nut -1- of the support on the engine. –  On vehicles with headlight range control, detach coupling rod for vehicle level sender from track control link → Chapter.

In order not to damage the joints of the top axle link if deflection of the spring on stretching is too high, the wheel bearing housing should be supported by a device e.g. the setting fixture -T20209 -.

–  Unscrew bolt -3- from track control link. –  Position engine and gearbox jack -V.A.G 1383 A- with suitable wooden block under subframe and press subframe upwards lightly. –  Thread off the screwed joint of the bottom steering link to the sub-frame → Item.   Note To prevent the outboard joints on the track control links and guide links from being bent too far, secure the links to the car body with a piece of wire or similar.

–  Unhook lower mount -arrow- on starter line from right engine console.

–  First remove the hexagon bolts -4- and then the bolts -3-. –  Remove the hexagon bolts -1- and loosen the bolts -2- enough so that the subframe can be removed. Installation Installation is carried out in the reverse sequence; note the following: Fasten sub-frame with aid of check gauge -3393- to body before tightening.

–  Hole -1-, hole -2- in subframe and hole -3- in aluminium bracket must be in alignment on both sides.   Note t  This locating method avoids the need for a subsequent wheel alignment check, provided that: t  Only the subframe has been removed and installed. t  The holes -1- and -2- were matched before the repairs. –  Protect holes in body for mounting check gauges -3393- against corrosion.

–  Place the sub-frame at its assembly location and insert the hexagon bolts -1...4- in their locations.

–  Screw on nut -1-. –  Insert track control links and guide links in subframe. –  Thread off the screwed joint of the bottom steering link to the sub-frame → Item.

–  Screw in bolts -3- of the track control link.

–  Hook lower mount -arrow- on starter line into right engine console. Tightening sequence   Note t  The threads of the bodywork can be made operational with the threaded insert (Heli-Coil) according to DIN 8140. The threaded insert must have the same length as the threads of the bodywork. t  Bonded rubber bushes can only be turned to a limited extent. The mountings of the suspension links must therefore only be tightened when the suspension is in the unladen position → Chapter.

–  Tighten the hexagon bolts -1 and 3- to 110 Nm and re-tighten to 90°. –  Tighten the hexagon bolts -2- to 65 Nm. –  Tighten the hexagon bolts -4- to 75 Nm.

–  Tighten the nuts -1- of the engine bearing to 23 Nm.

–  Tighten the hexagon bolts -3- of the track control link to 70 Nm and continue for 180°. –  Tighten the hexagon bolts → Item of the track control link to 70 Nm and continue for 180°. –  Install the stabiliser bar and tighten the bolts with the appropriate torque → Chapter. –  Mount the wheels and the tighten the wheel bolts → Running gear, axles, steering; Rep. gr. 44   Note t  If attachment to the bodywork was made with the test mandrels -3393- before the assembly of the sub-frame (before final tightening of the bolts), the wheel axle alignment can be dispensed with. t  If such a fixing has not been done, axle alignment is necessary. –  If necessary, perform an → Chapteraxle alignment. Setting of the running gear must be done with an alignment stand recommended by SEAT.
