I have a 03 with 55k miles 90% of them are stop and go with a 7000lb landscape trailer. At 45k my front pads were squeaking horribly so I had a friend of mine change my front pads with some Wagner Thermoquiets and since about 50k the right front is squeaking alot. I pulled the wheel off today to check to rotor, but it was perfectly smooth. Any idea what it could be??
