Ford Excursion :: Grinding Noise Occasionally On Small Bumps

We took our Ex to a local business and got almost 6k worth of work done prior to our trip. This included specific instructions to inspect the brake systems and replace anything that needed it. The work done included new front calipers, pads, hubs, new xrf ball joints, new shocks all the way around including dual fronts, a 6.0 tranny cooler and all new fluids. I alook tried getting a magtec differential cover installed but was told it didn't fit.

Long story short, while on the road we began to notice a grinding noise occasionally on small bumps. In reding ca our rear drivers side brake pads basically disintegrated and we were stranded while BigO replaced both pads, calipers and one rotor. They also advised that the slide pins were frozen on both calipers. This had no effect on the other noise I described.

Now that we're home we went back to the original shop and explained what happened. The owner agreed to take another look at the truck but basically said he stands behind his employees. He admitted that they chose not to examine the rear brakes to save usome "3 hours" of shop time. He also said that the rear brakes would've cost the same regardless of if they'd replaced them instead of BigO.

When my wife pointed out that our family had been first of all put in danger and secondly stranded by his worker's shoddy examination. He then preceded to ask why I insisted on doing so much work to such an old, high mileage truck. I left our truck with him so they could see if the sound could be traced back to anything they worked on and off course they didn't hear it.

I'm going back there tomorrow to take him for a drive and show him the noise which I repeat only started after their work was done. Am I wrong to be furious and think this crap is completely bs?
