I have a 1961 Vespa 150 and my oil seal in the rear wheel breaks everytime I get a new one. The wheel wobbles a lot and my l breaks are almost non-existent. It's been 6 months and I'm not getting any permanent solutions. Please help me with your valuable opinions.

Scratches or pitted with corrosion will cause leaking past the seal. Surface is on the hub Phil. Usually the damage is done to the hub and the driveshaft is ok. But if it's been ridden for some time like this you never know.

I had a look at the design... Hmmm..

Am I right in thinking, if the splines are worn and the hub's got movement on the shaft, the seal's just going to flog out in no time?
