There is no problem! This sound is normal for this vehicle! The sound <they say> comes form the suspension shackle as it goes up and down during heavy braking. I told them that this is NOT something that has been happening since I bought the unit. It only happened after I slammed on the brakes to see this supposed stripper walking out in the parking lot. (Sorry... No pics!) She had a VERY short skirt, seamed stockings and quite an a$$!.... Anyway... It started grinding then and has done so, under heavy braking, ever since.

They say that they lubricated the suspension bushings, shackles, etc so that MAY help the problem. I called BS on that crap! I said that it started when I slammed on the brakes! It is DEFINITELY a rotational GRINDING noise! They said they had it up on the lift... they drove it for two days and could not find anything out of place! I told them of a few post I had seen online about an emergency brake line mount that may be the culprit. I also told them I have read about warped rotors. (I doubt that is the problem!)

They washed my car for me so it was soaked when I picked it up. The service tech asked to drive with me to try to duplicate it before I left.... No noise! I could swear I heard it in rush-hour driving on the way back but can't swear to it. (I'll test it tomorrow.)

The bottom line is... There is no TSB about this so the dealer has blinders on. I must say that Moore Cadillac Hummer in Tyson's Corner, VA was very nice about this. (Though potentially very WRONG!) They went out of their way to TRY to make me feel at ease about taking off in it.

I will post again in a day or two as to what it does now. I'm pretty sure it will do the same thing! If it does... I'll go out of my way to slam on the brakes to make what ever it is wear out and show the problem!

I guess we'll see!

If anyone has any comments... Post away!
