Turns sharper when accelerating, Durango Steering Gear upgrade

Hey xjers
Just finished swapping out my 2000 4.0 with a '98 Durango steering gear box. I noticed it turns much quicker now, yet I still seem to have a dead spot, and when I accelerate, it turns sharper..
Anyone have an idea what's causing this? Could I have bought a faulty reman?
Thanks!

Did you upgrade your pump to a WJ one? If not you need to. You put in a bigger box and the factory pump isn't going to keep up. Only other option is looking an the PSC underdrive pulley.

Sounds like you drilled out the fitting on your power steering pump and now you have too much flow to the box which is overrunning the spool valve.

When I rebuilt a Durango box I noticed mine had a variable rate gear in it that moves the pitman faster as you move away from center and that the sector shaft doesn't travel a full 90 degrees like the stock box so you need to have the pitman arm centered when going straight and it will feel a little different and turn the wheels fewer degrees. I used a modded stock pump that blew the top off the box pulling the threads out. I am on a East Texas (stock box) ram assist now and it's great.
