I'm hearing a loud constant clicking-ish type sound coming from the front passenger side wheel well everytime that my suspension is under load.. basically everytime that I hit a bump or just any sort of roughness in the road. I take a quick glance in the well and this is the first thing that catches my attention.

Can I just replace the boot and/or ball joint? I know a full rack replacement can easily out cost an engine swap!

TREs are cheap and the best way to go, I wouldn't replace just the boot. But that's not likely to be your noise IMO, my guess would be a cv joint.

It looks like your control arms and tie rod ends need to be replaced anyway. As to the noise, that sounds like a bad CV joint. Check the boots for tears.

I spent about 2 hours on the highway this morning and one thing I noticed is that when under load my steering wheel would be stable and firm. As soon as I would let off the gas, my steering wheel would start to shudder, almost violently at higher speeds. The faster I was going, the worse the shudder was getting after I would take my foot off of the accelerator. I'd imagine this description that I just gave will pinpoint my problem. CVs for sure?

My CVs look like they're about a week old!

Before you say something about the stains on the inner CV (2nd pic) I'm pretty sure that's from water from my AC system and not grease. My AC system seems to drip gallons of water after a lengthy drive which I just got done doing and that's right in the area here it drips from. Also, the inner CV boot looks brand new as well and I don't see any tears or any grease nearby.

A few more pics of what I believe is the tie rod end:

That would be a nice upgrade but I don't need that entire kit to solve this problem.. at least I shouldn't.

What type of improvements did you notice with that kit though? :-)

I have that kit and it is absolutely awesome. Makes the car seem new again. Definitely get the full metal TRE's.

Your boots are cracked and torn. You can replace both sides inner/outer for cheap. These are for the S4, but I believe these are the ones I am rocking.

If not that, I would say the CV joint.

Just looking at stuff isn't going to do much. You need find the play. Pry at the joints, wiggle the wheels around. Putting your hand on each joint while having somebody else manipulate stuff is helpful. Sometimes the joint can be worn such that it only shows play at exactly ride height. That can make it a little trickier. But if the play is very noticeable while driving, it should be pretty easy to find even if the wheels are hanging.

I've not yet seen a good video that shows how to check the lower control arm ball joints. I have been waiting for a car to come in with a bad one so I can make a video.
