I am replacing my front ball joints and would like to know what else I need to replace while I am in there. This is my first time doing this on a four wheel drive. The axle is a Dana 44. I allready have the Moog ball joints and need to know what bearings, seals,ect.. to replace. Should I replace the axle u-joints at the same time even if they are in good shape? Any help would be appreciated.
