My steering went out I could turn left easily but not right at all so I replaced gear box. Issue after replacing gear box and resealing the front axle is it will turn right but wont turn all the way left. If you lift up the jeep and take pressure off the front end it will steer full lock both ways but with pressure it will only turn full lock right and about 3/4 left. So I took the new gear box and warrantied it but im having the same issue with my second box I did everything correctly to my knowledge but cannot figure out the issue ive tried everything any ideas would be helpful. Also anything asked I can answer

1988 jeep xj
Hd hiem joint steering all but trac bar is after market
about 5 inch of lift needs adjustable control arms
cv axles

 

Where did you get the steering box from ? and what does it do if you run the engine up to about 1500 RPM ?

 

Running 5" of lift on a stock track bar? Did you relocate it? Is it possible your axle is not centered? Did you center the box and steering before putting the pitman arm on?
