2012 Rubi JKU

When making turns, the driver seat seems to shift just a bit and make a subtle clunking noise; when making opposite turn it does the same. I had the dealer instal Katzkin and I'm beginning to think that they didn't tighten it or forgot a washer?

Any advice is welcome

 

To be more specific, I am sure it is the driver seat because if I sit and move around essentially shaking the seat, i hear a clunk and then a clunk when I shift my weight to the other side.

 

My JK did the exact thing when I had my Katskins installed.
Go back to dealer/aftermarket and ask them to tighten your seat bolts (mine had loosened just enough to let the seat move causing that clunking sound)
Once they did that the noise is gone and has not done it since.
Good luck

 

I've got a clunking noise in my driver seat too. It's coming from my wallet. The last 2 pennies I have after all these mods are banging together.
