Re: Suspension Bottoming Out?
I've purchased a new set of shocks that had a bad one in recent years, and luckily noticed it was not working properly before I installed, so got a replacement shipped. It is either a bad part, or improper install / assembly. Since you don't even know what parts they used, the shop supplied them, and they are responsible for fixing it; typically there is a one year parts/labor warranty minimum on the work done.
Springs do not ever just go bad like that and would not cause those symptoms. Check your receipt and see if they installed new strut mounts and lower front insulators, as these are also a must to replace when doing shocks.
