I changed a Wheel Bearing on my Volvo 244GL Diesel and it was a lot easier than on the W123.

The only difficulty at all was removing and reinstalling the Aluminum Collar that you press on to hold the Bearing onto the Axle Shaft.

I did not need a Slide Hammer during any part of the operation and I did not need a Dial Indicator or special Tool to adjust the End Play. In fact you do not adjust the Eng Play on it.

To me that is simpler and easier.

From an engineering stand point it may not be a superior design but it is a common design used on Millions of US Cars besides the old 82 Volvo. The design appears entirely adequate.
