When driving over bumps a clicking or squeaking from the rear leaf springs may be fixed by replacing the (leaf) spring tip liners and installing a spring clinch clip (kit available from the dealer).

Most Reported Dodge Ram 2500 Problem Reports
A vibration or shimmy felt in the steering wheel when driving over rough roads may be caused by a worn steering damper and tie rod ends. Also be sure the tires are correctly inflated, alignment is within specification and suspension components are tightened properly.
If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.
A loud buzzing or whining when the transmission is in reverse may be caused by a regulator valve in the transmission valve body. A revised valve was released that does not resonate. Careful diagnosis should be performed because other causes can create the noise.
A new overrunning alternator pulley often helps with drive belt squealing or fraying. Pulley alignment should also be inspected when the belt frays or squeals.
If a clunking or "loose lumber" noise is coming from the front or rear suspension, there are revised shock absorbers available that can help the concern. This is usually heard at lower speeds and colder temperatures when driving over bumps.
If the transmission delays initial gear engagement after being parked overnight or longer, it may be due to a suspect transmission cooler return filter. If the transmission was recently serviced and the part number for the cooler return filter contains an "AB" suffix at the end, a new filter should be installed.
If the engine cranks but does not start, or starts and stalls, the fuses should be inspected, especially the power door locks fuse. The power door lock fuse provides power to a module that sends the Powertrain Control Module (PCM) the "OK to start" signal.
The throttle body may malfunction in very cold climates causing symptoms at engine start up. A throttle body causing problems will require replacement.
A software issue with the sunroof module may lead to a battery drain while the ignition is off. This may cause a dead battery if the vehicle is left parked for a couple days, however reprogramming the sunroof module with new software may fix this problem.
