I also have a 08 Rubicon rock crawler and installed Ridgid light bar years ago. I also got the high pitch whistle from the cooling fins on back, if you put approx 1” wide strip of black duct tape and run vertical along fins noise will be gone.
For sure not the least expensive option but I just installed a Gobi rack yesterday and stopped by Rack Attack in Denver on way home. Picked up Yakima Sweet Roll kayak rack that will bolt right to cross bars.
Cut off hooks ? i pulled harness off old bumper and put on new. the little tabs dont all line up on mod bumper so I just trimmed off with razor knife the ones that dont align.
After i asked I did notice it, not sure if I can sqeeze in budget right now. if I did would they be installed at same time as rack and any install charge ? Thx
