installing grease fittings
I have a small backhoe at home and installed my own grease fittings, drilled, tapped and screwed in my own grease fittings where I felt I needed them. I grease each time I use it.
Would it be possible, advisable to install your own grease fittings at critical suspension points? As I write this I think not, probably these pivot points are now designed for no grease. I guess exception might be ball joint???
