Please note that some 2003 chassis (W20 and W22) had a 2 inch front stabilizer shaft. Often called an anti sway bar. In September of 2003 WH changed to a 2.5 inch bar. If your chassis has the 2 inch bar I would strongly recommend that you have the 2.5 inch bar installed. I did and it made a huge improvement in roll or side to side sway. This is from an email I got from WH in 2005: The part number for the Front Stabilizer Bar with Brackets is: W0005643. This bar was found to have an advantage over the original 2" bar, and was put into regular production on 9/2/2003. The installation is very straightforward. Remove 4 retaining nuts while supporting bar, remove bar, hold new bar in position, reinstall 4 retaining nuts, and torque to specification. This procedure is NOT meant to replace the service manual, but is a generalized procedure. The upgraded stabilizer bar has been shown to provide the following benefits: 1. Reduced Body Roll when cornering. 2. Reduced rocking when passed by or passing large vehicles. 3. Reduced rocking when traversing bumps on an angle. The installation procedure is below - I did not raise the coach, just crawled under it: Stabilizer Shaft Replacement (Front) (W20/W22) Removal Procedure 1. Raise the vehicle on a hoist 2.
