I think I may need bushings up front for my stock height 4x4. They look ok, but I am feeling some wandering when driving. I have a press but no adapters. Has anyone done this that could advise on how hard it is to do?

That’s 1 hell of a job, bub. These are the procedures required for removing the upper and lower CAs, half of the battle. Once you get them on the bench, I would estimate anywhere from 4-8 hours rebuilding each with new bushing & ball joints.

Nowadays, most folks will buy new control arm assemblies and swap them out as opposed to rebuilding the originals since the cost:benefit isn’t worth the extra time & labor involved.

If you had the cups and presser blanks already on-hand, familiar with the exercise then it might make sense. But if you have never done it before, hours could be spent searching and doing tedious little shit that makes you wish there were new full assemblies sitting in boxes on the floor.

Don’t remove and replace, or rebuild & replace without installing new ball joints as well. All of that work just for new bushings, then neglect the ball joints REGARDLESS of condition, is a major FAIL.

These components really need to be in a bad way for warranting such an undertaking. I’m usually the driver of the prevent maint bandwagon but front control arms isn’t for the faint of heart and you certainly need a large assortment of tools, stands, jacks, even more so to rebuild any components. You can get away with much less for a direct remove & replace.

Great info and input. I am pretty well equipped, but this is major work for sure... The upper looks easier than the lower. I'm gonna try and verify the bad bushings before going through the expense and pita for swapping a pile of heavy metal.

Just replace the whole control arm. Your truck will thank you
Jesus Christ! I did my upper bushings not too long ago, and its a pity to remove the old rusted ones off! That is putting it lightly, To remove even with a press requires some adjustment abd creativity, They wont straight up fit into it to remove. I had to use my press in reverse to make it work, I used a combination of bearing races I had laying around that matched the the bushing diameter, to remove and install, Installing is the easy part, its removing that will make you regret not just buy the control arm and ball joint already assembled. For the top ones, I would recommend just buy the whole arm, for the bottom that can be pricey, that will be a pain I can imagine, but might be worth it since you save some shekels.
