intermittant roaring noise in front end. will stop when 4wd is engaged or come to a stop. have replaced actuator
Thank you for writing in. Start by looking into the wheel bearings and CV joints. Both will cause similar noises. Various tests can be done at home with all 4 wheels in the air, but repairs are easier if you are properly equipped with a lift and specialty tools. You will want to make sure these test are done sooner than later, as these problems can get worse quickly, and will start to wear down other suspension and steering components. I suggest seeking professional repairs from a qualified technician. Good luck!
