Exhaust Rattle Noise or Vibration (Replace Turbocharger Exhaust Outlet Bracket)

Some customers may comment on a rattle noise or vibration coming from the engine compartment under various conditions. The effected vehicles include:

The turbocharger exhaust outlet bracket may break, allowing excessive movement and causing a rattle noise or vibration. Vehicles built after those listed will already have the updated bracket design.

Inspect for a broken turbocharger exhaust outlet bracket.

If the bracket is broken from the turbocharger exhaust outlet, remove the right exhaust pipe (1) and install the updated brackets to the turbocharger exhaust outlet (2). The first turbocharger exhaust pipe bracket (3) bolts to the right exhaust manifold, replacing the existing bracket. The second turbocharger exhaust pipe bracket (4) clamps around the turbocharger exhaust outlet (2) and bolts to the manifold side bracket (3). The bracket bolt (5) may have to be temporarily installed without the washer to engage the threads enough to initially compress the bracket and then reinstalled with the washer.
