You have basically two options if you want to continue using a Kiev 88:
1. Pay the cost of shipping/repairs to this body and justify the expense by knowing you have a serviced/sorted camera.
2. Buy a random used replacement body that may work perfectly for a day or years; it's a real crap shoot.
Yes, it's not inexpensive to have the body CLA'd by anyone BUT it gives you a certain degree of insurance that the camera will work function properly for a long time.
One bit of advice; should you send it to Arax, bite the bullet and send your magazines to them to match them to the camera body. I sucked it up and bore the cost and spacing/light tightness is spot-on.
Any medium format camera now is decades old and should be serviced before you start using it regularly or you will probably have some preventable issues down the road.
It's all a matter of how important it is to you to use this particular camera for your work.
EDIT: In any event, you should probably STOP winding and firing the camera until you get it serviced. You are probably causing damage to the gearing, which tends to be made of softer metal.
