Squeak coming from front end

[MeatMonsterAT4]

How many miles on your 2020?

Just turned 100,000miles. I'm the second owner. Previous owner had 3.5" lift which I removed and then an incompetent shop installed the Leveling kit with new Leveled UCA's and there is still persistent squeaking on the front driver side.

I am now having a similar sound on my ‘24. Will have them check the mounts. Thank you all!

Good news update. Took it to local GMC dealer where I have faithfully gone since 2016 and they diagnosed it as incorrectly installed new struts which ruined the struts/mounts. So GMC installed new OEM struts and strut mounts. Rides incredibly better now. It fixed 3 different squeaking and squealing sounds I (and the wife) were hearing. She says that the truck feels better now than when I bought it. So the problem is solved. I have invoiced the incompetent shop and asked them to reimburse me for what I spent on their misdiagnosis and faulty repairs and they said would help me out. So fingers crossed they do the right thing and reimburse me. Never going to any other shop again that isn't the GMC dealership.

Don't settle for that answer. I had a rear leafspring squeak around 2000 miles; during the third visit they agreed to rock the truck by jumping up and down on the tailgate step whilst another tech used a stethescope to conclude the rear springpacks were defective. Three weeks later they replaced springpacks, U-Bolts etc. and the problem obviously went away.

I now have the same issue on the passenger rear on my ‘24 1500 AT4. it’s driving me nuts. I’ll try this when I go to the dealership. So it was only a faulty springpack? @pinebaron

Yes. Dealer replaced both spring packs, ubolts, all hardware. New spring packs were dark in color and looked different from original, perhaps because they were recently manufactured.

Follow up from me. Was prepping on a Saturday to take the truck into the dealership. Pulled myself off the ground using my B&W hitch as a brace and heard the squeak. In my case, the squeak came from a slightly rusty hitch pin. Upgraded to a better pin and the squeak is gone.

1113,000. Updated as of today June 30th, 2026. GMC dealer replaced the squeaking strut mounts back in February and then I went and got it leveled with the Ready Lift leveling kit in April. Squeaking is back and it is GOD awful. Took it to GMC this morning and they said the strut mounts are cracked and need to be replaced and they will warranty them this time. But if and when it happens again they will not and he places all the blame squarely on the Leveling Kit. Not sure I believe him yet, but this is a real problem apparently.

Update on July 7th, 2026. GMC Dealer installed new Strut mounts and squeaking is completely gone and front suspension is quiet as a mouse and smooth as silk. Dealer was pissed though and says you cannot blend OEM with after-market suspension parts without consequences. They didn't charge for the work but they claim this is going to keep happening again and offered to remove the Leveling kit and return truck to true factory front suspension. I find all this very intriguing. Does Ready-Lift or any other vendor not give a shit at all that their products are damaging factory parts and performance? I'm ready to unload the truck at this point. This is a circular nightmare that I wish I had known before I bought it. I've come to the conclusion that if you have 10 OEM factory components in your suspension, and you replace 1 with after-market, you've completely jeopardized the safe operation of your truck. Change my mind, I challenge anyone to try.

The problem isn't that you level or lift your truck. The problem is who you go with and that OEM struts aren't designed for anything but oem.

When you go with a cheap solution i.e rough country, ready lift, supreme suspensions (if they're still around) etc. you get what you pay for. If you don't want problems, you can't cheap out on a leveling or lift kit. You have to buy from the top dogs.

Kryptonite, cognito, icon vehicle dynamics etc. and you have to upgrade your struts with fox, Bilstein, icon, kings etc

It's also important to either install everything yourself, so you can do it right or visit a reputable shop. Les Schwab for cheap isn't it. They installed a leveling kit on my buddies HD where his control arms now sits at 45 degree angle and ride on the bump stops.
