Well, I took it back to the Chevy dealer I bought it at last week and they fed me the same song and dance. They said the differential backlash was within Ford spec as it needed that slop to be able to lock into 4 high while moving. Ok, I guess I can buy that and I find that if I shift a certain way (much different from my MX-5 I am used to) I can keep it relatively quiet.
The brakes I just don't know what to do. They squeal almost constantly when just lightly braking. The Chevy dealer said it was because I have rear drums and that the semi-metallic dust gets built up in there and cannot escape. I believe it, but don't accept it as it is at the very least a terrible design.
Lastly, I still don't understand why when my HVAC control is on face/feet, feet or face, the AC is on. It was 73 degrees today and on face/feet it was so cold I had to add heat and I can hear the compressor running.
I would take it to a Ford dealer and have them fix it but I'll have to pay for it and will have very little chance the Chevy dealer will pay me back. At this point I'm trying to finance my wedding and the rear differential on my mx-5 which is why I'm driving the truck during summer in the first place.
Does anybody have these problems with their 07 vintage? Am I the only one?
