Clunk Over Speed Bumps

I believe this is exactly what you're hearing.

My UCAs were hitting my coils when the front suspension was suddenly unloaded. Jack up the front of your truck and check the clearance between your UCA and coil. It also depends on the clocking of your coil so it may be worse on one side than the other.
If that's the case, it's not really anything to worry about other than being annoying.

 

Yes, but wouldn’t the noise happen in other instances if the coilover was bad? The ONLY time this does it, is on a speed bump…

 

No not necessarily. Suspension is stupid like that sometimes.

 

I’ve only had the truck for like 2wks, I guess anything is possible. I don’t see any leaks or anything out of the struts, truck seems well cared for… it really actually seems like the clunk is coming from the bumper support area… does that change anything?

 

Time means nothing and defective parts are sometimes directly out of the box or shortly thereafter.

Additionally, have you checked your front radiator support bulkhead body mount bushings? They tend to tear up from the truck just existing. You may want to check them, and given that the truck is a 2013, I'd be willing to bet that they have never been changed out.

 

I did look at the bottom ones while crawling around under the truck, but they didn’t seem out of whack or anything and I guess I hadn’t considered they would make a clunk like that.. are they a possibility?

 

Here are pics of the lower bushings, they look original, but not sure if they look bad..

 

Oh my god.

They look like hammered dog shit. Replace replace replace! THEN recheck. If it still happens you have a busted internal in the suspension on those Bilsteins.

Hahahaha yep, just went thru your thread on the rad support bushings and am now aware of how terrible mine look! It doesn’t sound like the coilovers, like I said, definitely sounds like the drivers side front bumper which would point to the rad support bushing. I ordered the ES kit, should have it Wednesday. Thanks for all your help man!

 

In that last picture, is there a bolt missing?

 

I thought the same, but I don't think so - it's the bumper bracket. Not sure if the PO had something mounted there or not.
