If you are not in a hurry, the glow plug control module usualy can be easily repaired, I think Clarky has the info.
I used these lower control arms, seemed ok and are still running fine after 20k, which isn't a lot but time will tell.

The plan then was to get a set of poly bushes from jeep perf, and fit them to the original lower control arms, for the next swap out.
But as can be seen by the avatar, the other half had different plans and the son got the Commander.
