Having a new issue…after I stop for any length of time (not a stop light, but park)…I get a kinda clunk from the front end, took it to dealer they looked at it and said all was fine, but didn’t find/fix anything - it is still there, If I didn’t know better I would have thought it sounded like a brake caliper releasing…but truck is only two years old and I live in Texas (virtually no rust? Thoughts?
