Just finished changing ball joints u joints and unit bearings (wheel bearings)
Took all day yesterday and part of this morning but got'er done.
I have a ball joint press and actually know how to use it now. Just letting you all know if you want to do ball joints at an install party.
And no, it wont take 2 days. There were some tough lessons (time consuming) learned during the process.
If you haven't had your axles apart and have been in mud/water you should probably do it.
