knocking in my floorboards 01 S10

[GorillaGirl]

Ok so I have already read a lot of the topics already posted with the "same issue" except most people are saying they feel a knocking under the drivers side floor board when hitting bumps and such.

 

I have noticed that I can hear and feel a knocking under the floor boards myself but it is generally on acceleration from say slowing down to allow a vehicle to turn and then speeding back up or when I am slowing down from high speeds such as coming off an exit ramp from the interstate. Generally I don't hear/feel it when driving in town although sometimes it does.

 

I took the truck to the shop and found out I had broken motor mounts. So I replaced them (the shop showed me the issue before taking it in and even showed me the motor mounts when they were done). I have had the vehicle out of the shop for 2 days and I notice the knocking is still there. It isn't as loud so it seemed to have the same timing but I can still feel it.

 

I'm not convinced it would be suspension issues since I don't have it happening on bumps and things but then again I don't know squat about that kind of thing. I have read where some people are saying the bottom ball joint, steering box or tie rods....

 

Can anyone help me out with ideas? I really thought after replacing the motor mounts that would fix it!
