2005 Honda Civic Struts replaced now noise

I just replaced the four struts on my 2005 Civic EX SE Coupe with Gabrial Ultras. As soon as I drove it to the shop to have it aligned I noticed a thumping sound coming from the front passanger side. I also noticed the steering felt loose and sloopy, especially at speed on the highway. I had the shop double check all the bolts to make sure they were torqued correctly and then give it the alignment. I picked up the car and the thumping is still there plus when you pull out of a driveway so that the passenger side takes the dip first, it sounds like it’s bottoming out, this also happens over speed bumps or larger potholes. The steering is also very unnerving at highway speeds, it feels loose and any bump seems to make the steering wheel turn. I took it to the shop and they told me it could be a bad strut, I had them replace that strut and it still does it. Then they told me it could be the stabilizer end link, it was replaced and it still does it. I’ve had four shops look at this and tell me they can find no reason why it would be doing this and no one can fix the problem. Can You help?
