Had a leaking issue with the front suspension valve block and replaced, also replaced the tired compressor. Now the suspension is all messed up, left front normal, right front hyper extended, right rear normal and left rear is not lifting. Do I must have the GAP IId tool to calibrate or there's another way or perhaps something else is wrong. Your help will be greatly appreciated........

 

Make sure your suspension hight sensor is correctly installed.

It's possible to install it the other way around, where up is down and down is up
I had the exactly same problem and this was the cause. Rotating it 180 degrees fixed all the issues.

Good luck!

 

Thanks, I will check into that

 

Well… did you figure it out?
