i bought this nitro September 2011, noticed squeak beginning of may when windows were down and driving slow. took to dealership moberly motors in moberly mo they took tires wheels off, greased all they could, tightened things. 2 hours later was squeaking just the same. took again month later, same thing. it is very annoying, they ran beside car when going slow and put weight on one side to get it to squeak (it won;t do it unless in motion) friend of mine has 2008 dodge durango and hers does same thing is this a dodge problem?
