Need some help with the power steering on my GF's CJ7 as it requires A LOT of effort to turn when aired down off road and on road (have to air her jeep down to 7PSI to clear garage door). The Jeep only has 33's and at about 17psi offroad it takes pretty good effort (both hands tugging on steering wheel) from even me to make tight turns with her Jeep. My ZJ on 35's in contrast, I can steer with one hand crossed up and aired down to 12 psi so you can see the disparity. I was thinking about doing hydro assist, but that's probably way overkill for a jeep on 33's, so what do you guys think, power steering pump not working, steering box gone bad? Is there a easy and a relatively inexpensive upgrade to help with this? Any input would be great.

Thanks,
Fred R.
