The pinion seals in front diff and also upper and lower ball joints are being replaced in this video.

Aside from seals and ball joints I needed to purchase:

Ball joint removal kit.
A large press/gear bearing jaw puller (with the 3 claws) for the lower bushes.
Hammer - to tap the upper one in a little way to allow room for the ball joint removal tool to fit in the wheel well, to finish the upper ones off.

Vehicle has been handling like a new car since changing these.

I changed the diff oil after I reassembled everything.
