Servicing subframe - Audi A1 quattro — AUDI

🧭 Before you start

Strip the rear axle of wheels, springs, silencer, anti-roll bar and track rods, release the brake line clip and fix the subframe position with locating pins before lowering it 100 mm. Mark the bush position, extract it with the hydraulic puller and clear the old bush from the tube in a vice. Press the new bush in with lug, plate and thrust piece square to the direction of travel until the collar is flush, then remove the pins and rebuild the axle.

Fits: Audi A1 (8X, 2010–2018)

Don't miss

• Do not disconnect the brake line; only remove its clip so the subframe can drop.
• Fit the locating pins to fix subframe position before lowering, so axle geometry is kept.
• Mark the old bush against the subframe with a felt-tip pen before pulling it.
• Expect a loud bang as the outer ring shears off during extraction; that is normal.
• Lug, plate and the flat side of the thrust piece must all be perpendicular to the direction of travel.
