Just wanted to give an update. I did get the dealer to agree to shock replacement. Clearly it was blow. When we removed, it was not as smooth as the other side and had little resistance. We actaully knowing it was failed pushed it back past the seal, and it barely had any pressure. In fact, all the oil was mixed with air/water where with the nitrogen charge, that shouldnt happen as much. Been a couple weeks. Definitely quiet and rides like a z71. Took the bounce and lightness i was feeling out of the truck. Love this thing now. Thank for all the support!

Tried this, it does make the sound. THose horizontal cracks in pavement do it too. How many miles did you notice it took to go away? I only have 12k on it, might need to break in more, shocks could just be darn stiff

thank you!

I tried bouncing it, might not be moving it enough as i am not the biggest guy, but it sounded fine. However, another mentioned drive slowly over 2x4 and that duplicates it. Passsenger side is silent Curious, do you guys have z71 suspension with same white ranchero shocks, wonder if some are bad. Sounds like it isnt acting properly at low speed, probably a internal valve issue. My tech said bring it in, we are going to try shock and see if it improves/or stays the same. Either way, it is one more thing out of the way PS: i wonder if these damn trucks are too light, With all the plastic and aluminum, i notice the sound is bettter when the truck has cab full and it is warm outside

Okay i will try that. IS what you were hearing considered normal just bouncing or noise feeding thru the fenders? Or did you find something wrong?

What did you find out? what do you mean by pull down on the fender, are you saying the fender is loose or hitting while hitting a bump?

That exactly it! seen nothing wrong and my buddy is a 20 year certified gm tech, he is who works on these and my personal truck, and even he is stumped. ALso hard to duplicate problem Let me know what you find if anything.

So my 2019 z71 had a pull from factory. No biggie right, it was just tow, could have been the first pothole or delivery pulled it out of wack. But when the did the alignment, they said caster or something was off, and i noticed they moved the eccentric bolt on the lower control arm almost 1/4" from max on both sides. They didn't move the front eccentric bolt much on the front of the control arm. See pictures It seemed odd so i asked for a re-check and saw the specs, the truck is in alignment. They said some have been seen off this far from factory. Should i be concerned i don't have much adjustment left? Should i be concerned truck was this far out? Tracks great, just curious.

Hey guys, Got a 2019 Z71, bought new with 12K miles on it. Ever since new, it sounds like the front drivers wheel when hitting a bump at lower speed(around 15-30 mph) is almost bouncing, like a bad strut/shock/bushing. Had it checked thoroughly by dealer twice, everything seems tight. Had an alignment done too. Seems also to be noticeable at winter time(40 degrees or colder). Didnt notice much this summer, also dont notice at all at highway speeds. Anyone experience this or have a thought? Dealer is willing to replace strut but that doesn't seem to make sense either. I have even watched it out the window, and tire shows no sign of bouncing.

I see if can pull it from Drive to Low mode when driving. If I take off next time when towing, I might try that as I'll be able to see what gear it's in. Also I notice while driving it empty it hoops from 1-2 so quick and smoothly, and being the ratios are very close, I don't notice it. This is most likely the case when towing

Didn't say temp was issue, just commenting truck stayed very cool compared to my 2010 or 2014

Becuase id rather keep it in 5th when towing heavy loads. Sometimes it bounces back and forth between 5-6.

2019 Silverado 1500 z71 with 8K miles, 3.23 rear, 8 speed. Today I have towed about 8000lbs of cattle and trailer. I prior towed an old farmall tractor back. Both times when towing over 6000lbs, I had the transmission in L6, tow haul mode. Sometimes when taking off from a stop, it almost felt like the truck started in 2nd, not dropping down the first. Would it do that? Or is the torque converter just being floated as RPM's rise, and possibly I am not feeling the shift from 1 to 2. This transmission is crazy smooth compared to my 6 speed. Truck drives great otherwise. Ran it to town empty later, no issues. Even ran it thru the Low mode gears, and it starts in first normally. Thought maybe this was towhaul mode trying to avoid unnecessary shifting if still rolling. Transmission running cool, never over 180 even with that load at 60-70 mph. Thanks for sharing your experiences.

did the torque converter or valve body make it anybetter? or where they smoked already? These things are tuned for fuel saving which is awesome to some degree. I know plenty of ford, dodge and tundra people out there looking silly with their fuel mileage. However, I feel it is saving fuel although putting extra wear and tear on good trucks

When you say harsh downshifts, can you explain? My truck I notice if I brake hard, downshifts hard. Brake slow and soft, downshifts soft. it is like the programming of the transmission is set to grade brake down even under normal driving conditions. Also, what RPMS are you seeing down shifts occur? Mine usually are around 800-900rpm then rise to 1000-1200rpm, until down around 800rpm, then repeat for each lower gear except first, where it goes to idle I think my tranny as it has aged has got more clunky. 70+K and things just are not as smooth
