## ⚠️ Common Signs of Failure

-   Housing movement or misalignment
-   Wrong screw length fitted
-   Oil leakage at the housing joint
-   Abnormal driveline vibration

## 🛠️ Service Notes

-   Check the head, threads and seating face before reuse; a screw with rounded flats, a stretched thread or heavy corrosion should be renewed, not refitted
-   Clean the threads and the mating face so the screw pulls down onto metal rather than onto dirt or old sealant
-   Use a correctly sized spanner or socket fully engaged on the head, and support the component so the screw is not loaded sideways as it tightens
-   Refit the same washers, locking devices or sealing compound that were originally used
-   Tighten to the figure and sequence given in the workshop manual for your engine, pulling the screws of a multi-screw joint down evenly in stages
