About a month ago I put on a Rough Country 2.5" lift with shocks and springs and Spider Traxx wheel spacers. I went offroad and didn't have any suspension noise. I re/torqued the spacers at 50 miles so I know nothing is lose. A few weeks ago I had the dealer replace a differential cover seal and now when I go offroad and over minor bumps on a smooth road I hear a suspension rattle up front. I know I'll be told to re-torque the front bolts but I find it odd it started to make the rattling noise from the front suspension after the dealer. Suggestions?

 

Forgot, no wobble or vibrations.
