I purchased a 2012 Hyundai Santa Fe on which the previous owner damaged the spare tire hoist. When replacing the hoist I noticed what appeared to be mounting places for bushings to prevent the spare tire from rubbing on the chassis. I cannot find any reference to these bushings in the service manual. Do these bushings exist or are there just brackets aor their mounting. They may be as simple as rubber plugs, 4 each or a rubber part with two retainer stems attached. Please help find informaton..
