Bad Ball Joint?

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.
EDIT 2" https://motofablifts.com/i-30558324-17-18-chevy-gmc-silverado-sierra-1500-upper-control-arms.html

" 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'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!

      Software Update

      By kickass audio · Posted

      when it's greyed out that is it's way of telling you that it's downloading the patch in the background. Eventually it will be fully downloaded and then it will prompt you at ignition shut down to run the update. I highly recommend doing the update once you get home and can run it a few times. I've had several issues with updates not going the first time around and I had to retry the update multiple times in my driveway before it was successful.   Some updates are huge and take awhile to download. You can help it by connecting to your home WiFi and keep the truck on service mode for the ignition and keep it alive for awhile on a battery charger too. There are specs it needs to be in for updating such as a full enough battery charge, no running ignition, etc.

      Software Update

      By Chuck FB · Posted

      I am not techy at all but wondered if you have the truck running but sitting still in park as some functions gray out as soon as the truck is moving. I believe in the settings for updates you can choose for it NOT to update and I wonder by chance if maybe that was chosen before and now it won't allow you to chose to press update, I think that is back in the settings menu where it has all the items one wants on or off etc. Also I assume you have a wifi connection and checked that it has some signal strength, not that it would have anything to do with the grayed out updates choice in that case. What I am thinking out loud of here may be be of no value but thought I would suggest it, sometimes it can be the simplest thing that resolves an issue.

      Dave's Auto (custom engine builder) tear down of L8T

      By Chuck FB · Posted

      The so called rare failure that some certainly liked to tout ( die hard Ford fan boys ) as per the lifter failing and wiping out the cam. Back when it started happening the blame was being pointed to the lifters and honestly I never did hear anything myself conclusively one way or the other on that. Ford themselves in I believe 2024 had a technical bulletin I will call it that came out and for some engine platforms they were reprograming the engines idle speed but also they had a software update for the oil pump which then some time later was said what that software update did as to be increasing the oil pressure at idle. It is a good question if that issue was completely solved as one Ford specialist mechanic youtuber said he saw failures after that time period. Like anything there would be the variables, what oil is being used and the OCI and how much idle time gets put on an engine. I've seen some comments to claim that the L8T isn't so happy with high idle time either but I also know that companies that require their vehicle to idle a lot on the job don't tend to get the oil changed often enough for all those hours of idle time and go off of the odometer.

      Lower trims ( WT, Custom, Silverado ( aka LT )

      By bwiese · Posted

      My 2026 Silv. 1500 WT (reg cab/short bed/4wd) has the 40/20/40 with storage in lower middle seat as well as the fold-down center bolster/armrest.   With the dual glove boxes this is about as much storage as possible in a std cab IMHO. Bill

      2026 Silv. 1500 WT reg cab: how many speakers do I have? Is amp module separate?

      By bwiese · Posted

      I have a 2026 base 1500 "WT" regular cab with basic Chevy "Infotainment 3" 7-inch screen/radio. How many speakers do I have If I want to upgrade? Is the audio amp separate from the radio/display unit]? [I listen to classical and it gets a bit raspy at slightly higher volumes. Don't need a sub etc.] Do I have two or 1 speakers in the doors? etc. Thanks Bill  San Jose
