I had popping that I think has been isolated to my hood latch. I could somewhat create the sound by turning the wheel while stationary, but could never get it to occur with the hood open while someone else was at the wheel. Got me thinking. Pushed on the top edge of my grill with hood closed and sure enough it popped pretty readily. Must be some flex in the hood. Shot some lithium grease into the latch and onto the latch bar. Haven't heard it since. While driving, it occurred in similar situations to what you describe.
Very ill advised to stack that. Anything over 2.5" will drastically accelerate suspension wear. You'd want to consider uca replacements and maybe even a diff drop. There are 3"-3.5" kits that exist and some people run with success, but most of them include uca and diff drop. The further you stretch your suspension the rougher the ride will get. Better shocks will help offset some of that, but not completely.
I have no issues. The knuckle was not contacting the steering stop on the LCA like it was supposed to and allowing my wheel to turn too far where the tire would make contact with the nub that jimmyboy8301 is referring to. I've since had the shop add another stop where it actually makes proper contact and all is well. I don't rub anywhere now. Mind you, both of us have stamped steel arms. Ymmv. Regarding the zone shocks, I don't know. Never ran them. Went straight to fox.
I believe people have done it with your UCAs, but it really depends on the tires. I have stamped and I clear barely with 275/60/20s. Zone 4.5, bilstein 5100 front stock height, fox 2.0 rear. The narrow 33s look a little on the small side, but not bad. I'm in the same boat, only 10k on the tires. Will be putting 34's or 35's on when they wear out, but they look fine for now.

MBSierra17 replied to MBSierra17's topic in 2014-2018 Silverado & Sierra ModsUpdate: it would seem the new knuckle is not making contact correctly with the steering stop on the lca, allowing the wheel to turn further than it should. Shop will be adding a new stop which should remedy the rubbing. Will update next week.
MBSierra17 posted a topic in 2014-2018 Silverado & Sierra ModsAs the title suggests, is anyone aware of any aftermarket UCAs that are compatible with stock wheels and a zone 4.5" lift? I have a 2017 sierra 4x4 CC with stamped UCAs making contact at the ball joint with tire wall. Looking at options between replacing wheels with less positive offset, or just replacing the control arms. I know there are several options out there, but I'm sure some would require the same offset adjustments.
Apparently spoke too soon. Noticed today there is slight rub on the nub of the UCA at the ball joint on sidewall. Doesn't manifest at full lock, so I guess that's how I missed it. Not sure how I want to resolve it. 275 is already a narrow tire, so I'm a little baffled. Looks like 4 options: monitor rubbing to see how bad it really is over time. 1/4" spacer (not a fan of these slip ones) 1" spacer (don't really want to go that wide) New wheels (Hopefully can get close to cost by selling the stock wheels...)
Apparently I spoke too soon. I found no tire contact at full lock, but noticed today that at approximately 1/4 - 1/3 turn off the wheels the tire sidewall makes contact with the ball joint area of the UCA. Very very light. Not sure how I'm going to resolve it at this point. Don't want 1/4" spacer, don't want a full 1" spacer either... Guess I'll be looking for new wheels and seeing how much I can get for the stock ones.
Stock wheels, 275/60/20 falken wildpeak tires for now. Had them already on with the leveling shocks, but only 10k miles on them so I'm waiting to go bigger tires until these wear out. Probably 275/65/20 once these are done.
I think the suspension geometry being stretched is just as big a factor, if not more so, than the spring setting. I imagine you'd see a similar improvement to me. My wife even commented that the ride seemed better with the lift.
