2006 Dodge Ram 2500. 5.9. I changed my ball joints and axle shaft ujoints this weekend. Drove my truck about 100 miles after and then my abs and parking brake light came on. Any idea what caused this?

 

Did you try the key trick and get any codes?

I'd guess you bumped one of the sensor connections. If you have them up front, they should have a connector around each knuckle, and one in the back that I think is supposed to be on top of the diff. Unplugging an ABS sensor will throw those lights up.
