I have OME heavy duty coils in the front with 10mm OME "trim spacers" and OME medium coils in the rear. All of a sudden after a few thousand miles of driving on and off road I've developed a knocking noise when I hit a rut or bump in the road. I checked all control arm bolts for torque, checked the ball joints, checked the motor mounts, checked the shocks, etc. Can't find anything loose. Then yesterday I noticed that my front lower control arms are touching the frame at the frame end. Like, you couldn't slide a pencil in between the arm and the unibody. It seems like a super tight fit. Is this normal? Anybody else have this issue? The control arms are new also, but they are not Mopar brand.
