Did you replace your wheel bearings when you did your front houseing? The only reason I'm asking is because I'm assuming your using wheel spacers and with 2.5 b/s you will be puttting quite a load on your wheel bearings with the 40's.
Yeah, it got a fresh set of bearings from a Marlin rebuild kit last winter when I built the rig. The front axle probably only has 1500-2000 miles on it along with the engine
