Removing and installing suspension strut/coil spring: Audi TT Mk1

🧭 Before you start

Remove the wheel, coupling rod, brake hose clip, speed sensor wire and noise insulation, then free the drive shaft and tie it up. Remove the pinch bolt, spread the housing with 3424 and pull it off the strut, wiring it to the subframe. Fit the strut with lubricated mounting at 60 Nm, raise the bearing housing on a gearbox jack to refit the bolt, remove 3424. Strip or build up the strut with V.A.G 1752/1 and its adapter.

Fits: Audi TT Mk1 (8N)

• Special tools named: 3424

Don't miss

• Note the installation direction of the pinch bolt between wheel bearing housing and strut.
• Coat the strut mounting with assembly lubricant G 294 421 A1 before fitting.
• Strut to suspension turret takes 60 Nm.
• Do not press the gearbox jack against the ball joint when raising the bearing housing.
• Make sure the coil spring is seated correctly in adapter V.A.G 1752/4 before compressing.

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.
