Step 0 – Raise the vehicle securely on jackstands or a lift, in order to gain access to the rear subframe. Important: Install the 034Motorsport Subframe Mount Inserts one at a time to avoid shifting the subframe! Step 1 - Using an mm Socket, remove the rear bolt securing the rear subframe to the chassis. Step 2 – Once the subframe bolt is removed, use a small pry bar to separate the factory washer from the rubber bushing.
Step 3 Remove the factory washer and set aside. Step 4 Apply silicone grease to the insert as pictured below.
Step 5 – Align the 034Motorsport Rear Subframe Insert (601-0037) with the voids in the factory subframe bushing. Step 6 – Install subframe bolt using an mm Socket. Note: We recommend replacing the original subframe bolts with new pieces, as they are stretch bolts that are intended fora onetime use.
Step 7 – Torque new subframe bolt to 115 Nm + 90° Turn. If you opt to reuse the stock bolts, torque them to 120 Nm with Blue Loctite. Step 8 - Using a T Torx driver, remove the 2 bolts securing the rear subframe cover.
Step 9 – Using a flathead screwdriver, release the clips securing the rear subframe cover to the underbody. Step 10 – Using a mm Socket, loosen the outer 2 bolts from the subframe support bracket.
Step 11 Using a mm socket, remove the final bolt securing the rear subframe bracket to the subframe bushing. Step 12 With the support bracket removed, the subframe bushing should be exposed and appear as the picture below.
Step 13 – Apply silicone grease to the insert as pictured below. Step 14 – Align the 034Motorsport Front Subframe Insert (601-0036) with the voids in the factory subframe bushing.
Step 15 – We recommend replacing the factory stretch bolts when installing subframe inserts. However, if you choose to reuse the existing subframe bolts, apply some blue loctite to ensure they stay put. Step 16 – Reinstall the subframe mount bracket and bolt, tightening just enough to allow for alignment of the two additional bolts.
Step 17 – The support bracket should be snug, but with enough play to align the remaining 2 boltholes to the chassis. Step 18 – Align the subframe mount bracket and reinstall the two mm bolts. Torque the mm bolts 55 Nm.
Step 19 – Torque new subframe bolt to 115 Nm + 90° Turn. If you opt to reuse the stock subframe mount bolt, torque to 120 Nm with Blue Loctite. Step 20 – Slide the rear subframe cover back into place, and secure using the two T Torx screws.
Step 21 – Repeat stepson the other side of the vehicle to install the remaining two inserts. Step 22 – Double-check the installation, and verify that everything is torqued to spec. Lower the vehicle from the lift or jackstands, and enjoy the improved performance
