LCA skid plate

I have RCI LCA skids and just had my 20k service done, and when i got the truck back my skids have been popping and making noise when there is a shif in weight, like braking or acclerating, and makes noise on bumps. I am taking my truck tommrow to my lift shop to install my new boss kit and i will have them look at it, but was wondering if anyone had this issue and knows a way to fix.

 

got them on my 4runner, never an issue

 

Unless they did alignment, lca shouldn't been touched.
My guess is they didn't tighten the main skid or got it a bit crooked maybe so it taps on something sometimes.
Or they left a tool on the wiper cowl. Had shop leave a bracket and bolts on my cowl once. Heard it rattling on bumps when I drove away.

 

My lift shop figured it out, had my 20k service at toyota and i think the mechanic was drunk
