- Clunk/pop/knock sound coming from the front when going over speed bumps or other obstacles.
- General wandering feeling of the front wheels when driving over uneven terrain or obstacles.
What I've done/plan to do:
- I have replaced sway bar end links and bushings. This helped the roll slightly but problem persists. Struts were also replaced about 40k miles ago, so I think they can be ruled out.
- Next I plan on replacing lower and upper A-arm bushings and ball joints.
Questions:
- Am I correct in targeting a-arm bushings and ball joints and sway bar end links? Are these symptoms of something else?
- Are there other components I should replace while tackling the bushings and ball joints? Inner/outer tie rods, wheel bearings? cv axles? I've read the oem wheel bearings are pretty robust and a hassle to replace. Also seems a good time to do the brake upgrade. Any other suggestions while I have all these components off?

From your description of the problem I think you were right in tackling sway bar bushings and end links first. They are all good now?
I think next you should be questioning the struts, shocks and springs. Thats the number one thing to be causing body roll and instability. What was put on 40,000 k ago? If it says Monroe on it consider it past due for replacement. I'd suspect someone cheaped out here.
Could also be tires really. I had a set of Nokians that were horribly unstable.
And then continue with your list. I can't really see wheel bearings, tie rod ends, CVs or for that matter control arm bushings causing body roll issues. Unstable steering for sure but not body roll issues.
Do you have a 200lb rooftop tent up there? My money is on a poor suspension setup.
