Unhappy Poison Spyder Rock Brawler II Clunk!!!

Hi everyone,
I have searched a lot and could not find one person complaining about the Rock Brawler 2 rear bumper tire carrier combo for the Jeep JK.

So I have a 2015 JKU Freedom with PS Brawler Lite front bumper and Rock Brawler 2 rear bumper/Carrier combo. The problem is that there is a really loud clunking noise coming from the driver side rear bumper. NOT the carrier. I took the carrier off and drove without it and the noise is still there. I can replicate the noise by pushing or jumping up and down on the driver side rear bumper.
Can not figure out what it is.

In the PS instructions it says to drill a 3rd hole on the outside of the frame rail, behind the 2 factory bolting points (see picture) to correspond the hole on the Rock Brawler 2 bumper. On my JK, there ALREADY was a hole there that is oblong shaped so i put the clip nut and everything fit perfect. I am thinking that this might be the clunking as the factory hole is little bigger than the hole that PS wants you to drill.

Anyone out there with this bumper having the same issue? if you hop on the driver side and jump up and down you can hear it (in a garage or quite environment) or can feel it metal hitting metal. Please let me know, i really want to make that noise go away as it sounds really bad from inside the vehicle.
Thank you all.

Right after i posted this, i went to check the bumper again and i can actually pull the bumper up (lift up and down) with the carrier and the tire on it and feel that there is a gap somewhere. But i don't understand how because the nuts and bolts are as tight as it gets.

I have the same Poison Spyder bumper and it was built like crap.
I had to drill all new mounting holes on the frame mount flange while prying on the spare tire carrier so the CB radio tang on the tire carrier would not break my rear window...

I also had the same issue as you are describing.
I ended up changing to grade 8 bolts of a different length. I went shorter on the bolts because the non threaded part hit the nut before it was tight.. the bolt seems tight but the bumper is loose..
I may have even put a spacer between the bumper mount and the frame.. dont remember though..
I also have to add a pin to keep the spare tire rack fully closed to the bumper.
am not really impressed by Poison Spyder at all.

but make sure your bolts are not to long to compress the mount flange to the frame

I am just kinda happy that i am not alone .
Thanks for the reply, i will try your method.

My tire carrier works perfect even thoigh i had trouble putting in the bearing seal.
But the bumper, just like u said, every bolt is tight as mother but i can still move the bumper up and down. Anyways i will try the new shorter bolts, i might even drill a new hole.

If you get a chance, would you be able to ck to see if you've used a spacer, and if so what did you use?
Thank you so much.

Maybe stop by a local jeep shop as I inquired about installs from PS and they told me that they only manufacture and don't do installs. I hope you get that thing fixed. Maybe the thejeepshack in San Diego could help you out.

I will definitely stop by them, 4wheelparts store was not much help even though i bought it from them.
But turns out i am only 2 hours from PSC HQ, Breven there asked me if i can stop by, so i think i might just do that.

Breven at PSC also told me that it might be the rear track bar making that noise but i looked and there is no moving / loose parts down there. Oh well,

Thanks again.

That's weird since they told me otherwise. Hopefully they do fix it. Good luck bud.

4wheel parts owns poison spyder..

could the movement be from the tire rack itself where the swing arm mounts to the bumper. there is a bearing that has an adjustable nut for play

Yeah, i hope i can get fixed too because tgis thing was pretty penny, you guys know.


I actualky have taken the tire carrier off and drove it like that and the clunk was still there but not as loud. So there is definitely something wronge with the bumper. When the tire carrier is added on, the clunk gets louder. I keep thinking it is the 3rd bolt on the side of the frame closer to the back of the jeep.
I didnt get a chance to go to any shop to get it checked and i just found out that PS is not doing any installs like you guys said. They dont even have any tools up there, so i didnt want to drive all the way out there.
I am at the point where i will take the whole thing off and install another brand's bumper/carrier combo. Maybe AEV.

Well, it has been a while but i finally got to work and figured it out myself. It was the Rock Krawler rear driver side sway bar link that came loose. i grabbed the sway bar itself and rocked it, the noise was coming from there. So tightened the sway bar link and the noise is gone, so stupid of me to blame it on the PS bumper. Thanks for all the help though.

It speaks volumes that you let us know what the actual cause of the clunk was and that you are clarifying the issue. It's completely understandable that you would deduce it was coming from the bumper based on the timing of the noise.
