Hey I am new to this and thought that I could get some answers.

I have an 04 Galant GTS and as of right now. I know for a fact my front struts are bad. I have been to two different local shops and both have confirmed this. Now the problem is that I am hearing a thudding noise (like im driving over rumble strips) when I start to get up to higher speeds. The last shop I went to looked at it and said that they saw bushings missing in the back and a loose link?? They also told me that my rear struts are locking up. They were not very clear on what they were saying let alone sounded confident. So if anyone else has ideas or has delt with something like this, Let me know.
