Saludos to everyone in the forum!

Today I installed the Rugged Ridge RRC rock rails. Install was easy. I was able to keep the Rubicon rock guards on which I think gives the JK a clean line along the sides. Looks mean, but as soon as I hit the pavement I'm getting this knocking sound on both sides every time I pass over any kind of irregularity on the road. It looks like the RRC is knocking up against the Rubicon rock guard.

Any suggestions?

 

Both are solid and should be unmovable, did you check the body bolts on the rails to make sure they were tight? Mine have never made any noise nor had any parts that would make noise, I don't have rubi rails though.

 

Here are some pics

 

Looks like it's close enough to knock to me, stick some rubber between it and see if it goes away.

 

Is there any part of your suspension which might be coming in contact with the new rails?

 

I think that is a good idea Use rubbers

No, everything is clear from everything else. I'm sure that it is the RRC vibrating against the factory rock guard. I might use some rubber between them as ranwitscissorz suggested or add rubber spacers where the RRC Rail is attached which will create some space between them.

Any other suggestions????
