I had the same problem on my 210. The boots are really cheap to replace but dust and sand could have easily fallen in there with the torn boot. I opted to replace the tierod ends completely. I sent it to a mechanic for this so half the cost went into labour. The inner rods were cheap so I decided to have them replaced too seeing as I was already paying for the labour. In the end it depends on how much youo want to spend, but on an old car it might be a good idea to change the inner and outer tierods seeing as you are going to dissamble everything anyway.
