spare tire mount

I installed a new tire carrier back in August since I upgraded to 35s. It’s a Barricade HD Tire Carrier with Mount. Over the past few months there’s been a LOT of squeaking noises coming from back there, but all the bolts are tight and I cannot for the life of me figure out where this noise is...

Looking for a lightly used Teraflex Alpha HD Tire Mount. Just the tire mount kit, I don’t need the gate support. Please PM me if you have one, or will have one soon, for sale. Thanks! Mike
