99' XJ 4.0 swap

Hey guys new here. Just bought a 99XJ 4.0, 4x4, AT. Had a nasty rod knock and exited the block on the way to the shop, lol. On the way the steering felt a bit sloppy, more like a rack issue not pwr steer pump. I have already put new gaskets and seals in the motor I'm going to swap. My question is, is the steering rack easier to replace while the motor is out and would the rack be the culprit if al are good? Thanks!

If the motor is out, then yes the steering is easier to get to, as is pretty much everything else.
Inspect everything, and account for any lift it has. If it's lifted and the steering has not been addressed, then that is a likely culprit.
Far too many just slap springs on a rig and call it lifted. Far from the truth when they leave steering geometry, driveline angles, brakes, and so on untouched.

Gotcha, it has a rough country 3" lift w control arms. What are some things I would need to address (if a 3" would cause issues) while I'm in process? It's completely stock except for the lift. I bought it this way.

Let me clarify, when you talk about steering geometry, how do you correct that

Do some light reading in the XJ tech section. There are tons of posts there about it.
You want the trac bar in line with the drag link as a rule though, so have a look at it and see how far off it is.
You also need to beef it all up if the tires are oversize, and think about a reinforcement for the steering box mount. The unibody can and does shear there.
