Replace the knife shoe or the whole window balance?

I have several of these windows where the channel balance knife shoe (part 15-014)has broken. On a couple of them both sides are broken and the top portion of the window falls down unless the window is latched closed. Do I need to replace the channel balances (19") on these windows or can I just replace the shoes?

Generally a broken balance fitting is a sign of needed replacement balances, however if the balances are less than 5 years it may be worth trying to replace the fittings. If you do decide to replace just the fittings, you will need to clamp down the balance cord in a vice so that it does not jump out of the block and tackle. Take care, it is under a lot of pressure. Be sure to wear safety glasses.
