If you still have your spare hanging on it, take it off and see if it gets better.....especially if it is larger than the original. If this solves your problem, consider spare relocation.
If the spare is NOT hanging on it, you may have damage to the area where the hinges are bolted. If this is the case, you may need to reinforce that area.
