What version of the 2007 Dodge Ram do you have... 1500, 2500 or 3500... 4x4 or 2x4... Regular, Quad or Mega Cab... Is it bone stock or do you have a lift on it...
The 3rd gen trucks are known to have several issues that cause the steering to be loose and or sloppy. They are also notoriously known to get "Death Wobble" as the trucks age, some people have started to experience it in as little as 50,000 miles. Use the search function for this forum and type in "Death Wobble" to learn more about it.
Any way, there are several cures to tighten up the steering that Ram owners have found to work...
1. Steering box stabilizer that ties the steering box into the frame rails - http://www.custom-diesel.com/dodge-p...lizer-4x4.html
2. Upgraded steering linkage - http://klmperformance.com/mopar/mopa...grade-kit.html
3. New track bar (Adjustable/one with poly bushings instead of the stock rubber bushings) - http://www.dieselpowerproducts.com//...FfFj7AodU2sA3w
The Carli track bar in the link is a common one that a lot of guys upgrade to, including myself for my 2006 Ram 2500 4x4.
4. New steering shaft - http://www.borgeson.com/xcart/catalo...p-1-c-109.html
5. Upgraded/Beefier steering box - http://www.borgeson.com/xcart/catalo...p-1-c-108.html
Factory ones are known to fail early, new upgraded box and steering box stabilizer fix this issue.
6. Front Sway Bar End Links - http://www.suspensionmaxx.com/index....mnuf%5B%5D=176
Beefier and they also use poly bushings instead of the stock rubber bushings.
7. New HD Ball Joints - http://www.carlisuspension.com/dodge...nts/index.html
Factory ones tend to fail rather quickly.
The above 7 items are basically most of the items people install when addressing the 3rd gen truck steering issues.
