    Grin... Taking your advice, I youtube'd about uninstalling/re-installing control arms. Ran across this video. I'm not sure why, but this guys attitude and selectively colorful words he uses all throughout the video just seem to really add to the instructions. Make special note of "Engineer Johnny" in the video, as I've had these same type of thoughts allllll the time when driving/working on vehicles. I bet if Pickle had this guy at his side when installing the Prodigy turbo, that 27 hour install would have been cut in half, and been fun to boot.

    That may be the greatest install video for a control arm, ever.

    Update... The control arms have grease points at the body side. I'm not sure if it was the install shop, or if they came from the factory with zerks, but either way, they have them at the body side mounts. Unfortunately, Engineer Johnny (see a fore mentioned video) didn't put the zerks in so they point down at the front, and put in 90 degrees zerks at the rear so you can't access them through the access holes!!! Stupid Johnny....

    I unbolted one of the front lower control arms at the body and examined it. It sure seemed like this was the part making all the noise. It had an inner shaft on a ball that could move all around, surround by a poly bushing, and then the control arm. It was obvious it needed grease. So, given that I'm looking for a long term solution, and Engineer Johnny had the right idea but poor implementation of access, I just decided to drill new 7/32" holes, tap them with a 1/4" tap, and insert new zerks. Greased away until it was oozing out the sides, did the same for the other three lower control arms at the body, and then jumped on the jeep restlessly. No major squeaks!!! Took for a test drive, and so far, fairly quiet. I've never installed zerk grease points before. If I had known how easy it was after you bought the correct tap and zerk sizes, I would have done it long ago. Watch out squeaks, or you might get zerk'd!!!

    So, for today, with sub 80 degree weather, my squeaks are mostly gone. I say mostly as the reality is you'll always have some from all the different bushings and articulation that goes on. But at least when I start of from a full stop, or come to a complete stop, my Jeep no longer announces itself to the entire world that I'm a brand new 2014 Jeep (sarc.) Hope this holds. If not, I'll just grease the sucker up again until the mount points are dripping grease.

    Hope this thread has maybe helped others with their noise Jeeps.

    Excellent. I'd like to see a brief how-to with pictures of how you did the zerk fitting. I've never done one myself. I've pulled bolts and installed fittings, but never drilled and tapped a joint to add one where one didn't exist. Drill press or just a hand drill? Sounds really effective.

    Because they are simple enough, I didn't think to do a write-up. If I do another one, I'll take pics.

    Process is:

    1) Drill with 7/16" drill bit.
    2) Tap with 1/4" x 28 thread tap bit (since it's only for a zerk, I just put it on my cordless drill and went really slow.)
    3) Screw in 1/4" x28 thread zerk (straight, 45deg, or 90deg angle.)

    In my case, since I tapped it using my drill, I'm sure the threads were not _perfect_ so I also put some teflon tape on the zerk to make sure it was in tight. Who knows if this is good practice or not. The reality is, they were for greasing the rubber bushings on my lower control arms, so it's not like I was really concerned if this was best practice or not.

    They do make zerk's in different sizes. I ran across metric versions of 6mm, 8mm and 10mm. The problem is, the auto store didn't have taps that matched the thread count. Seems like 1/4" is the standard US size (when, oh when will we get off this stupid english measuring system. I truly hate it.) One thing I couldn't figure out is they had 1/8" zerk's, and they are bigger than the 1/4". How does a smaller measurement equate to a larger threaded fitting?

    After posting this, I did run across this site that shows a bunch of different zerk's, and I read on another forum that if you're going to put one in, put in the larger size (not sure why they said this, they just said, if you're going to do it, do it right by installing a 1/8")

    I see on the following site that there are tapered zerk's, straight zerks, zerks called PTF. They seem to give a nice write-up of each and why you'd use one over the other.

    crate of mice is funny... Squeeks are not.

    Im glad you solved this. Others will be able to use the info. If I hear a squeak in my jeep, i have to investigate until I find it. Sometimes it takes a long time.

    so whats the prognosis on the pro comp lift?

    has this squeak problem turned you off them?

    Would you do it the same again? or go with synergy or RK?

    Squeaks are 100% gone now that I'm greasing the right spots. Jeep is silent over bumps and other stuff. I have to admit, I think that Pro Comp gets a bad wrap. I watched a video recently of all the testing that they do to make sure that their product meets various standards. In the video below, they show passing the FMVSS 126 test (appears to be a stability control test.) I've also seen videos about their design and fabrication processes that appear pretty solid. I don't know enough about the other lift manufactures, but I'm curious if the other lift manufactures go through the same sort of stuff as I've seen Pro Comp go through? I'm also not so sure I understand what people don't like about Pro Comp. At this point in my experience, I'd buy a Pro Comp Stage 2 lift again unless I had compelling reason to buy something else.

    As for me, I'm not hard core into off-roading. I go enough to know that the suspension hasn't let me down so far, I've been happy with the flex I'm getting out of it, and I've been happy with the ride quality thus far. Unfortunately, I haven't driven any other lift kit, so I have no comparison.

    Not the best pic, but here's my rig at the top on some rocks after a Jeepin trip.
