Yes it is common problem with Canon 17-85, but this is not the only one lens suffering from similar problem. The earlier diesing ATX tokina suffer from the same problem.
It is not the service department that you have to bleame. This lenses have design problem.
1. No the spare part doesn’t cost 10cents. For tokina and canon was just bellow 10 Euro with send costs.
2. centring of lens grpups should not be a problem since you ether don’t remove the lns group or you remove the several stacked lenses
3. the biggest problem is the dust. Best do it on clean room. However I assume that your old 17-85 is already full with dust inside.
I already repaired 2xTokina 100macro,1xTokina 12-24 and 1xcanon 17-85.
The reparation of canon was not as fast as described at the film – at least mine lens had some glued components. I find Tokina ATX easier to service
PS: Don’t ask me to repair your lens. The first lens I repaired because was challenging, the second one repaired for fun.
