Clunk/popping noise after level

Recommended Posts

Hey guys I bought a 2015 GMC Sierra this year. I recently installed the RC 2.5" levelling kit and am now getting an odd popping/clunk noise from the drivers front end. Now I'm aware of the noise that's from the top a-arm hitting the bump stop but that is not it. I have inspected it and triple checked all torque settings. It happens usually at changes in elevation while turning for example pulling up into a back alley etc. But it seems to be related to the brakes. From what I can tell it happens whenever the brake is applied in these situations. Not always but often. I've even felt it applying the brakes on a flat road with no bumps while turning around a corner. Any ideas? I've done some research and heard it could be a broken brake pad spring but I haven't taken the caliper apart. The truck only has 10,000miles and the nearest dealer is 100miles away as I'm in a remote area for work more then 600 miles from home.

Did you ever track this down, I may have just picked up the same noise.

Sorry for the late reply, I never did track it down it just kind of went away after I installed the bigger tires shortly after. I -think it was caused by the UCA hitting the bump stop with enough flex, which I guess is a good thing considering its designed that way to help your upper ball joint. Either way after installing my bigger 285/75-17 tires it all went away.

Also a sqUeak when going over bumps, thinking I'll start with new sway bar end links and bushings. Hope I don't have to end up doing lower ball joints and have to take crap apart again.

Me too. I'm trying this as well. I think torque for ax nutz is 180s (foot/pounds).

 

With the creaky rear leafs, its hard to tell, but there is def noise in the front... Now re-torqued we'll see what the next few days hold.

It's more than likely strain on the a arm bushings from just putting in keys. Proper leveling is kys, shocks and upper a arm. Other wise the geometry get outta wack and stuff starts to wear wrong then fail. Any new noise is not good. I learned the hard way but I just traded it in.

I am having this same issue after I installed the 2.5 inch leveling kit from auto spring on my 2014 Sierra Z71. Sounds just like the CV joints. My kit was a 1 3/8 spacer on top of the strut. I also replaced the passenger side axle shaft due to a torn boot and still have the same popping noise while turning the steering wheel and moving. I will be getting my new 275/70 R18 BFG AT TA KO2 tires today with an alignment. Hopefully the noise goes away.
