So let me give props to Rosenthal Mazda of Arlington VA. Tons better than Ourisman of Laurel MD.
Now they looked at my problem starting with the brakes. They attempted to shim the brakes even after I told them I barely got the caliper over the new pads with the piston compressed. They had to try of course before checking that off the list. The next try was for the spline greasing. Surprisingly enough it worked! I will keep my ear on it, but it seems to have worked.
Now came the time for the bend-over. I have 45K on my 2007 and am on the extended warranty, therefore I owe $100 at least if it is covered under the warranty. Brake jobs are not covered. So I cringed and asked what the damage was.....not a dime, it was covered by the shop. My opinion of Mazda dealer/service departments has changed.
