Crunch, Crunch, when turning

[Windrider]

I now have 450 miles on my new truck. 17. 98mpg on the first tank. (I have a fer piece to go tomorrow so I filled it up. )

Last Friday I had a Rhino Liner and Western nerf bars installed. Now I get a crunching noise when turning corners. It's worse when turning left.

Do you folks think it's the bars or the liner?
(Wife thinks it's the liner, I think one of the mounting brackets on the bars are loose. )
I have tried tightening the bolts on the bars, and I didn't get anywhere. Of course, I only weigh 160lbs soaking wet.

I can get access to an impact wrench if I need it!

Don't see how it could be the liner. If you were rubbing against it wouldn't it rub off? I'd double check the brackets. Can you see any signs of contact?

Your nerfs must be mounted too far forward. Do you have mudflaps too? When I get snow/ice/mud packed behind my mudflaps they'll contact the wheels when turning. Ripped 'em off a few times too.

You're not the only one Mark.

I backed up through a snowbank and the rear flaps caught on the tires and they flipped up backwards. It made all kinds of noise.

Quick update!

The crunching sound was coming from behind us, hence the wifes feeling it was the bedliner.

I got under the truck and did some tightening of the nerf bars and it helped a great deal.

The truck may have been in a bind when my bars were put on. The bolts didn't move even 1/4 turn, but it sure did help.
