Lower ball joints

[nominous]

The difficult part is removing the shaft from the hub, requires muscle, crowbars and hammers and usually ends in shouting or grazed knuckles lol.

Found that to be a swine with my typical methods, then read on hear an idea which worked first time and did both in 30 seconds.
Use a long pole (big jack handle here) stick under the chassis, on top of the lower arm, apply pressure at the end downwards.

Give me a lever long enough and I can move the earth.
