Chrysler is recalling about 1.2 million Ram trucks to fix front-end problems that could lead to steering troubles.

The company announced three recalls on Friday. It wants to inspect the trucks and says only 453,000 will likely need repairs.

Chrysler said Friday in a statement that it knows of six crashes and two injuries involving the 2008 to 2012 Ram 2500 and 3500 trucks that are being recalled, and one crash with no injuries from the other recalled models.

The trucks are being recalled because tie-rod ends in the steering system may have been installed improperly, which Chrysler says stemmed from technicians misinterpreting instructions. Those tie-rods could be out of alignment, which Chrysler says can lead to steering failures.

The company has since updated the instructions and the parts involved.

Customers to be notified by mail next month

The first case covers 842,400 Ram 2500 and 3500 trucks from 2003 through 2008. Chrysler says 116,000 were repaired with tie-rods in the steering system that could be out of alignment.

The other two involve trucks with tie-rod assemblies that were replaced in previous recalls. They cover 294,000 Ram 2500 and 3500 trucks from the 2008 through 2012 model years, and 2008 Ram 1500 four-by-four mega cabs. Also included are 43,000 Ram 4500 and 5500 four-by-four chassis cabs from 2008 through 2012.

Customers will be notified by letter in December, and work could begin in January, the company said. Owners of Ram 4500 and 5500 models can take their trucks to dealers for interim repairs because parts may not be available until late next year, the statement said. The interim service would involve realignment of the front ends.

Chrysler said about 968,000 of the affected trucks are in the U.S., with another 157,000 in Canada, 37,100 in Mexico and 18,000 from other countries.
