just got off the phone with GMC parts and he said this is in my truck.. part # 22818981 where do you recommend I go to look at upgrading this and making it plug and play?

My RPO code on build sheet is UQA. Know anything about that one? Thanks

Not to thread jack, but you guys seem to know an awful lot about this.. i have a 17 Sierra all terrain fully loaded slt with Bose system... how can I figure out if I have a factory sub? I don’t think it has one but I’d like to check... also how hard is it to add one and how much would it cost?

Update.. GM applied good will and replaced the drier rear door lock actuator.. I ended up paying $135 total. Does the tech still get paid when that happens? I hope so... So Friday they called me and said the truck was fixed.. I had to send my dad to get it... gets it home, NO AC, blowing hot heat. The ticket said the AC Compressor broke from the back side? I immediately took the truck back... using a light they detected the lines or a line was cracked... had to leave the truck and they said they would fix it... very frustrating, but they gave me a loaner. i just hope they take their time and actually get it fixed correctly.

I’m not sure, but they called me and said they replaced the compressor for no charge. ive currently got them looking at why the driver rear door doesn’t always lock, they said it’s probably the rear door lock actuator and want $315+ tax.. that’s insane

Thank you a lot. I appreciate it. It’s going back Monday morning, I hope they don’t try to screw me.

Looking at the schematic posted it doesn’t look like that, are you sure? if the bolts for the compressor have to come lose and the compressor was loose wouldn’t the refrigerant leak out?

2017 GMC Sierra All terrain. 61,500 miles Dealer has replaced leaf springs, brake vacuum pump, water pump and belt... Now driving the other day AC quit working, look under vehicle and refrigerant was every where.. I immediately noticed a bolt loose and it seems like it doesn’t want to tighten back up... Anyone seen this issue? I am out of warranty. I wonder if GM will give me any assistance? Could this have anything to do with them replacing the water pump? any help is appreciated...

My truck was making a “chirping” noise and noticed it when it was in v4/v8 mode transition... clamped the valve open.. noise gone. i agree with the other guys, something cheap and easy to narrow down

No clue man... but I will give an update. Less than 1500 miles later, the noise has returned and it’s just as bad as before. Back to the dealership Monday... very frustrating

Just wanted to give an update.. I reached out to Chevy via social media.. I ended up going to a dealer. I was out of bumper to bumper warranty and they waived the diagnostic fee.. I can’t say enough about the service I received from RICE Buick GMC... they diagnosed my suspension noise to be the rear shackles needed to be replaced... I had to pay a little out of pocket but they ran the calculator and assisted a lot. I drove the truck and it drives like a 2 year old truck should, no noises, no creaking, no popping.. feels solid

I replaced the rear shocks with bilstein shocks. My truck is making this god awful noise. I can’t handle this shit anymore. $40k trucks don’t make this noise. I have bought waterproof grease to lube the leaf springs, nothing makes a difference. It sounds like something is going to fall off.. shocks didn’t fix it

I will check it out.. Yeah I couldn’t find all of those threads so i will sort through them.. Thanks i definitely feel like this “pop” is coming from the rear end, but I guess it could be the leaf springs. I might consider replacing the springs, that’s how bad this is bothering me.. any recommendations? I won’t be using GM stuff

What do you mean box mount bolts?

Guys, I have a 2017 GMC Sierra All terrain with 50k miles. I have developed a noise i hear when traveling slow and going over bumps or when the rear is put on uneven ground it seems like. The noise is either coming from the rear or center bottom of truck... almost like a light clunk or pop I searched and found some threads about bad rancho shocks, today I installed Bilstein 5100 series shocks on the rear and the noise subsided a little it seems like, & the ride quality feels better.. HOWEVER I still hear this noise. Is it the leaf springs? Do these trucks have bushings that wear? Could it be the rear end? I read something about some special lubricant for GM leaf springs.. Anybody have a part number? Where do you apply the lubricant? This noise is driving me nuts... Any help is greatly appreciated
