Rancho 9000 install question

Installed a set of 4 Rancho 9000xl's on my 12 F250. The stock shocks were a year old with 9000 miles, very little towing. I have had the new shocks on a week and haven't been impressed, the ride seems stiffer don't know about better. I now have what seems like a vibration or slight thumping feeling in the drivers side floorboard. It could be in my mind since I am focusing on everything thing, since I have installed these shock. My question is- I have checked all of the shocks and everything seems to be tight what could be causing this feeling?

On a side note, I thought I would change the shocks back to the factory ranchos just to see if the feeling was still there. I compressed the front shock and they had absolutely ZERO rebound, and the rears were terribly slow. I don't know if that is the way there are valved or they are just worn out. If anyone has any insight let me know.

Thanks

There's another post here from someone saying their new 9000s seized up and rode really rough... May be worth pulling and checking.
Just food for thought.

I have tried different setting. Just put them on 2\2 and like the ride. Still have a certain feeling in the floorboard, like a slight banging. I have checked and everything is tight.

No issues here after my install, I have all 4 corners set at 3 and the ride is amazing. For towing, I will set the front to 5 and rear to 7 which still makes for a smooth ride. Not sure what your issue is. If I think of anything, I will post it up. Good luck, hope you figure it out.

I believe I have figured out the issue. My drivers side Front shock will not compress. It seems to be locked up.
