Rods in rear are bent causing tires to wear

Do you mean the tie rods or are you just looking there and see a part that looks bent? if both tires are wearing uneven, it could be just a rear wheel alignment that you need. did you just buy this car? it's possible something under the car is bent from a previous accident, but if you had this car for awhile and this problem just began then it may be just an alignment........good luck..p.s......if both tires are wearing uneven then it's unlikely a" rod "is bent , there would have to be a " rod " bent on both sides which is too coincidental.
