| FORD: | 2005-2007 Mustang |
2005-2007 Mustang GT vehicles equipped with the 8.8 inch limited slip axle may exhibit a moan/groan noise when making tight low speed turns.
This may be more noticeable when the axle is at full operating temperature.
The noise may also be confused as originating from the brakes or steering system.
SERVICE PROCEDURE
- First, verify the concern.
- Make sure the axle is at full operating temperature.
- Perform several full lock turns at low speeds in both directions.
- If the noise is verified to be in the rear axle, proceed to Step 2.
- If the concern can not be verified or the noise is not coming from the rear axle assembly, do not continue with this TSB and follow normal diagnostics in the Workshop Manual (WSM).
- For vehicles built before 10/22/2006, replace the limited slip clutch pack. Install the new limited slip clutch pack kit.
- Vehicles built after 10/22/2006 were built with the new limited slip clutch pack. For these vehicles, add 1 bottle of Motorcraft Additive Friction Modifier to the axle. Perform several full lock turns at low speeds in both directions to force the lubricant into the limited slip clutch pack.
NOTE: DO NOT INSTALL NEW LIMITED SLIP CLUTCH PACKS IN VEHICLES BUILT AFTER 10/22/2006.
