Full Hydro Questions and Advice

[4wdOwnage]

I currently have a 8v in my tracker and have ran full hydro with a single ended 8" 1.75" bore ram for a couple years now with 31" skinny tractors with no issues. I have a PSC TC series 1650psi 4.5gpm pump and a 4.8ci (i'm guessing on the orbital) all of which before were on a sami front axle which was using heims on the drag link with a simple tab and a simple ram mount on the top of the axle above the diff and had 1 finger steering. I then put 2 trips on the 35" tractor tires I have now and didn't really notice any steering issues.

Recently I swapped all of that over the the toyota axle I bought which already had the TG hi-steer setup with FJ80 ends and I used the tab on top of the axle as well as the one on the drag link to mount my ram to. In the process I had the orbital rebuilt because it leaked, had the cylinder rebuilt, as well as the PSC pump and now first trip out in the woods the steering is horrible unless i'm moving or have a good amount of rpm's the steering simply won't move as if it's in a bind. I have a 5" pulley on it and am not sure what to swap out next to remedy the problem is it really going to be noticable going down to the 4.5" recommended pulley or is my money better spent just purchasing a larger diameter bore ram? Any help would be greatly appreciated.
