Clean it, I think you can get new boots pretty cheap and new grease.
I’d get the stabilizer bracket. Blaine had the size of the bolts that were smaller on tie Rod adjuster so I could rotate the sleeve, these guys may know as well, I thought was a good add.
Rubicon axles plus Currectlync, good find if it was reasonable.
