Speedi sleeves are not cheap...no matter the application.the offset seals I've used don't cost any more than a regular seal. Now for me to have a spacer machined...that will cost me more than buying a sleeve or offset seal. If I had my own lathe or had a good friend who had one than I'd whip one up..but since I don't..yes Speedi-sleeves make a good repair I'm not knocking them at all. I use them when i need to...many times.Was just commenting on the fact they are tricky to install on an axle shaft.
