Default help please

hi i am new to this forum. I have an 05 grand prix with a problem. Whenever i brake or accelerate there is a snap and or crackling sound coming from the left front area. I had it checked out and thread lock was applied to the welds because the dealer said it was the cradle welds that crackle. That cost 300 to do and it did not make a difference. They now say that if that did not work then the cradle has to be replaced at a cost of 2 grand. The damned car is not even 3 years old yet. Does this sound normal or has anyone else had this sound happen to them? Thanks

There is a TSB out for the aluminum cradles about this. Though I haven't heard of it being so pronounced, but the TSB is just as he described. Small spaces in between the metal need to be filled.

There is no danger to the weld strength, it's only annoying. IMO, it could also be that the cradle bolts are loose.

I've posted the TSB number on here before somewhere. Otherwise I'll have to look it up in the SI manual again.
