Just in case you still want to try it. Here are some pics of the guide rod mount removed without taking the lower control arm off. Again, this should only be done if the Lower Control Arm (LCA) bushing is pliable because it puts a tremendous angle/stress on it.
Pic 1. marked the guide rod position and loosen the bolts in the rear. I think they are 13mm. Also loosen your shock from the top so it can angle forward easily as you jack it out.
Pic 2 and 3. Put a portable hydraulic jack (an example from
Harbor Freight) into position. I used the weight of the vehicle on the jack stand as a base and pushed against the lower control arm with a block on it. I have the floor jack underneath for extra support just in case the jack stand slips.
Jack it out until the guide rod mount clears it's resting spot and you are able to unscrew it from the rod. The suspension will be pushed way forward and will look fierce and scary. But this is OK if your LCA bushing/bearing is good and you have the top of the shock loosen enough.
Pic 4. Install the new mount to the right location and release the pressure.
Pic 5. Tighten everything to spec.
