I have a 2018 Silverado with a 2.5” RC level kit. Occasionally/sporadically when making sharp, slow speed turns (usually when parking) I’ll notice a faint “clunk” coming from the front end. The truck itself has 33k miles (about 6k w/the level kit). 
 

Could this be indicative of a bad ball joint? If so, is it normal for a 2.5” front level to wear a ball joint out that quickly? Thanks

Did you keep the stock UCAs?
If so, your upper control arm ball joint(s) may have expired.
Any level installation should have a UCA replacement for the height of level over 2"

Yes, they are the stock UCA’s. I know I took a gamble keeping them, now I may be paying the price. I’ve heard replacing upper ball joints isn’t cheap, so I’m fearing that price may be high..

It's about $275 for the ones I bought - Motofab UCAs for a three inch Motofab level kit.
I also got the Motofab 1" rear block lift and a 1.5" rear spring lift.
My installer charged $335 for the entire install so, I would think just a UCA chang-out would be the price of the UCAs and, maybe, $150 or so?
EDIT: My installer mentioned he would never install a level without proper new UCAs.

" Corrects the ball joint angle for 2.5"-3" front leveling kits "

Price is actually about $290, sorry.

Good to know. If it does end up being a bad upper ball joint, I’ll probably just swap out the stock UCA’s for aftermarket ones. 
 

Like I said, the clunk is really sporadic and only happens once and a while. Is there anything else that could possibly be causing it? I haven’t noticed any uneven tire wear (yet) etc..

Not that I'm aware of in my experience.
As long as your sway bar links and steering links are good, it usually comes down to the UCAs.
See my edits above. :)

Thanks for the links! I have replica 20” GMC Honeycomb wheels, judging by Motofab’s website I’ll need wheel spacers? Aren’t wheel spacers usually frowned upon? Or maybe I’m just regurgitating something I read somewhere..

I have 18" wheels and 35s, virtually no rubbing - didn't know the recommendation for spacers.
I'd try to stay as far away from wheel spacers as I could!
EDIT, again: they only call for 1/4" so that seems reasonable.

I took that gamble and lost..... Now I'm looking at the DirtKing UCA or BDS UCA....

I'm pretty happy with the Motofab UCAs.
Ruining a 3" Motofab level (with 1.5" Zone body lift but that doesn't affect the geometry) and, really, I don't notice any rubbing on 35x12.5x18s.

Your ball joint pressed itself out! Totally legitimate reason for upgrading now!

    • Indeed a proper drain tap or drain valve with adapter that has a hose on it that opens up the valve as the adapter goes on is a slick setup and have that for certain highway tractors etc and other equipment that came from the factory with a tap but this L8T is pretty darned good other than me doing it on the floor and easy to touch hot exhaust and am not as agile as I used to be !. If I really want to pull a hot filter on an engine I will use an insulated set of thick neoprene gauntlet gloves but I am not in the hurry I used to need to be so things are done more relaxed and in theory somewhat safer ... I think LOL.    And as I mentioned the unique shape of the Amsoil 1 quart containers, while they might not work as well as an offset pour spout container for some awkward engine location applications, they are working a lot better with my Lisle funnel kit because of how they prop up on all four corners when upside down resting on the rim of the funnel where the typical quart container would never stay put without holding onto it. 
    • Well, I just hit 100K a few weeks back, and I can honestly say I have not had any major issues with my '21 5.3 Crew cab.  I have done most routine maintenance, oil changes, air filter, tire rotations, and a transmission drain and filter change (not even a full flush).  A couple of months ago, I started experiencing the dreaded CLUNK when coming to a stop, sometimes hard enough to literally push the truck forward! After researching here and in other forums/youtube videos, etc, I was thinking it's the slip yoke. I finally had a chance to take it to my local mechanic today, and he was not able to recreate the issue.  Amazing, since it does it nearly every time I drive.  He also said he can't simply grease my slip yoke/driveshaft splines, because I have a 1 piece driveshaft.  I am not sure what else I can do.  Has anyone else had this issue or have any idea what else it could be?
    • This is where the Fumoto drain valve comes in handy.  No mess and able to change oil hot, like right off the interstate hot.  Flows nice and you can direct it into a container. As for the oil filter, I use an old dixie cup or plastic one from McDonalds. It contains the oil as you pull the filter down and not all over your hand.
    • Well, if it did change from lifters to rocker arms, at least it would be easier to fix as they fail.
    • Doesn't hurt to try.  It's my understanding that you have to run it at least 4 or 5 oil changes for things to get clean.  Think about it, your engine didn't get dirty in just an oil change so over time it will slowly clean. It's the safest way to do it and not have seal issues.      I remember  a product that came out a long time ago, AutoRX, it was an additive you put in the oil and then drove for 3k miles. Some saw improvements and some didn't. It was suggested to use a non synthetic with it at the time. Same observation, use a couple oil changes and give it time to work. It also stated it worked best if you could drive on trips to keep the oil hot.  I'm sure if you ask AI it could tell you all about it.
