Mud is bad, and can cause a lot worse than that. I swore off of mud about 20 years ago once I realized what I was doing to the vehicle. The final incident was when it caused the front caliper to seize up completely. I had to pry the pads away from the rotor with a screwdriver, and then only use the emergency brake the entire 60 mile drive home.Woke up this morning and cleared off the mud. Went for a test drive and the wobble is gone! thanks for the advice I didn't realize some mud could do that.
