Replacing the rear axle housing cap can be difficult at times.
A friend solved the problem with some old scrap iron pieces and a good welder.
The rear axle housing cap is placed on the axle and this device is then placed on the axle.
One or two smacks on the small end with a large hammer easily installs the housing cap.
Thanks for sharing, Looks like it would work great. The seal cap can be easily damaged.
James, You don't have to make a tool, Just use an old center shaft from a worn out brake drum. It will do the same thing. Works great.
