Removing and installing wheel bearing housing, front-wheel drive vehicles — AUDI

🧭 Before you start

Remove the wheel, speed sensor, caliper and disc, then the coil or air spring. Mark and remove the adjuster screw, free the shock absorber and link bolts, and take the housing off. On refit, fit the housing, run the bolt with spacer in loosely, tighten it at the bolt rather than the nut, refit the spring, brakes, track rod, transverse links, sensor and wheel. Check and adjust wheel alignment as required.

Fits: Audi A6/A7 C7 (4G, 2011–2018); platform code 4X

Don't miss

• Hang the caliper so its weight does not strain the brake hose or pipe.
• Do not press the brake pedal with the caliper removed.
• Mark the adjuster screw position against the wheel bearing housing before removal.
• Tighten the bolt connection at the bolt, never by turning the nut.
• Tighten bonded rubber mountings only in the unladen or reference position.
