SUBFRAME, Servicing, Front Bonded Rubber Bushing For Rear Final Drive, All Wheel Drive (AWD) Vehicles: Installing

WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

Installation is the reverse of removal, with special attention to the following:

Before installing the bonded rubber bushing, make sure the Spindle T10254/5 is able to fit through the hole in the inner core of the bushing. The hole drilled into the inner core of the bonded rubber bushing may prevent the Spindle T10254/5 from sliding through. If this is the case, it must be drilled out.

WARNING:

Wear protective eyewear while drilling.

-- Gently pre-load the bonded rubber bushing -2- with cover horizontally in the vice clamp as illustrated -1-. Be sure not to damage the outer layer of the bonded rubber bushing.

Step 1, 11 mm drill bit

Step 2, 11.5 mm drill bit

NOTE:

Marking is needed to align bearing with subframe.

When pulling in the bearing, the grooves are masked by the tool.

-- Coat the rubber bonded bushing with Installation Lubricant before pressing it onto the subframe contact surface.

-- Install the rubber bonded bushing with the marking -arrow- into the subframe so that the marking points exactly in the driving direction.

-- Place the tools on the front bonded rubber bushing as shown in the illustration.
