XV1024 2009 Dodge Ram AAM 925 14 Bolt Front Axle Exploded View

The 14 Bolt American Axle Manufacturing (AAM) Model 925 5,500 pound rated Front Beam Axle with 5-link, coil spring suspension debuted in the 2003 model year Dodge RAM 2500 and RAM 3500 4x4 trucks. The differential and 9-1/4" gear set are more than adequate for the stock Cummins Diesel or gasoline engines and rarely pose major problems unless severely abused or neglected. However, the same cannot be said for the rest of the axle. Ball Joint failures with this axle are often a reoccurring problem due to the comparatively small size of the ball joints and the steering geometry of the axle. The life expectancy of the original wheel hubs and axle universal joints is only fair to good. Another known issue with these axles is the rivets holding the axle tubes to the differential housing can loosen up causing alignment and tracking problems.

The 2009 model year axle is somewhat of a transition unit as it has some features of 2003-2008 axles and also some of the 2010-2013 era. In addition, the steering knuckles and outer axle shafts are unique to the 2009 model year. Parts availability for 2009 axles is variable. Due to the low 2009 model year RAM truck production numbers, those parts that are unique to 2009 are often difficult or impossible to find.

‌

‌Available Axle Ratios were 3.42, 3.73, and 4.10 for all models except for the Ram 2500 Power Wagon which has a 4.56 ratio axle. An open differential is used. For Power Wagon models, the open differential is augmented by an electromagnetic coil assembly which can activate a dog clutch to lock both axles.

‌

2009 was the last year RAM trucks used a 1485 series axle universal joint that fit axle shafts with a 2.92" inner yoke span. The inner axle shafts are the same as 2003-2009, however the outers are specific to 2009. Effective with the 2010 model year, the axle u-joint size was upgraded to 1555 size (3.702" inside yoke span).

‌

2009 RAM AAM 925 14 bolt front axles are a non-disconnect type. The 5-link suspension has four control arms located behind the axle and a transverse mounted tracking bar. The tracking bar attaches to the passenger side of the axle housing and driver's side of the frame. A loose tracking bar can contribute to poor steering response and uncontrollable shaking (Death Wobble).

‌

Other names for the AAM 925 include Front Axle - 9 1/4 AA, 9-1/4" AA, AAM 9-1/4", AA925.
