That statement assumes the axles are orginal to the car!

I've put axles in several W123's and they were all 81+ and most had two homokinetic axles.

Steps:

Determine what axles you have in your car
Determine what your budget is going to be
Make a decision on how long you expect the axles to last before future replacement.

Then you can make a good decision on a replacement!
