Subframe Servicing

Subframe Servicing

Special tools, testers and auxiliary items required

• Torque wrench (VAG 1332)

• Engine and transmission jack (VAG 1383 A)

• Hydraulic press (VAS 6178) with pressure head (T10205/13)

• Hollow piston cylinder (VAS 6179)

• Tensioner hooks (VW 552)

• Assembly tool (T10301)

CAUTION!
Before starting work, stabilizer bars must be coupled in vehicles with separable stabilizer bars. Otherwise, there is the danger of injury caused by unintentional separation.

- Depressurize hydraulic system for separable stabilizer bars using.

- Hook in tensioner hooks (VW 552) on both vehicle sides in upper opening of wheel housing - arrow A - and in upper control arm - arrow B -.





- Lightly pre-tension control arm to prevent damage to ball stud caused by ball joint.

- Remove noise insulation below engine/transmission.

- If present, remove shield - A - from steering gear (2 bolts).





- Remove bolt - B - for steering column universal joint at steering gear and remove universal joint from steering gear.

With Separable Stabilizer Bar

- Disconnect both hydraulic lines - 1 - and electrical connection - 2 -.





Lines and wires must not be mixed up when connecting!

- Check whether color marking is present on front in driving direction. If no longer present, apply a new one.

- When loosening hydraulic lines, counter hold using open-end wrench.

Continuation for All

- Remove coupling rods from stabilizer bar.

- Remove strut from lower control arm.

- Subframe, locating. Refer to --> [ Subframe, Securing ] Subframe, Securing.

- Install insert of floor jack in engine and transmission jack (VAG 1383 A).

- Place engine and transmission jack (VAG 1383 A) and a block of wood - A - under engine carrier and press lightly against.





- Remove bolts - 1 and 2 - for subframe.





- Lower subframe approximately 70 mm using spindles (10-222 A/11).

- Install two M14 x 1.5 x 90 bolts, for example bolts (N 104 281 01) to secure engine carrier to body on left and right - 3 - sides.





- Remove engine and transmission jack (VAG 1383 A) from below engine carrier.

Continue with removing front bonded rubber bushings. Refer to --> [ Subframe Bonded Rubber Bushing, Front ] Subframe Bonded Rubber Bushing, Front.

Continue with removing rear bonded rubber bushings. Refer to --> [ Subframe Bonded Rubber Bushing, Rear ] Subframe Bonded Rubber Bushing, Rear.

- Mount subframe on body and remove locating pins (T10300) (second mechanic required).

Further installation is in the reverse sequence to removal.

With Separable Stabilizer Bar

- Bleed hydraulic system for separable stabilizer bar. Refer to --> [ Separable Stabilizer Bar, Bleeding ] Procedures.

Perform road test after repair work; if steering wheel is crooked, vehicle alignment must be performed. Refer to --> [ Wheel Alignment ] Wheel Alignment.
