Front end clunk after level

[RPaul]

I am embarrassed to say after being optimistic on here about spacer leveling kits, I now have a minor potential issue....

 

When turning the wheels and driving slow, I often hear pops on front end. I believe i have closed in on the issue and believe its to do with the sway bar.

 

Everything is tight, and the level is new, I don't believe there is any damage yet.

 

 

I am asking for help on tightening and troubleshooting the sway bar and popping noise from it.

 

Any advice? this is driving me crazy

wanted to clarify, the truck is a 1500 GMC Denali with ARC, level kit is 2.5" Rough country spacer

Hey, did you have any luck figuring this out? Just put a level on my truck this weekend and had a clunking. Everything is tight, got it aligned and the shop said they tightened up the sway bar end links and the rattling seemed to go away but now it’s back again. Don’t really want to have to take it off now but seems like it’s a common issue from some of the forums I found.

Check the top strut bolts. They’ll seem tight when the suspension is hanging but then at ride height they will have slop and be loose. Impact them down.

When you complete your final torque down of the nuts for the suspension, do it with the truck on the ground.  Torqueing to spec on an unloaded suspension is no bueno.

thank you, ill let my off road installers know this solution. you would think they knew this already. hmm

Replying to this thread because it’s the first thing that pops up on Google. I had the same issue and it ended up being the sway bar links. GM updated the sway bar links in 2022 with longer ones. 
 

if you have a 2019-2021 Silverado, you added a leveling kit and you’re hearing a clunk at slow speeds check your sway bar links. Have someone rock your truck side to side on the front and go underneath of it and give it a listen.

 

You will need part # GM85590925.
