Steering n axle project

Hello,

I'm in the process of of tidying up both axles and steering on me disco1 so i have a couple of questions that need answering.

So here goes:

I bought these ball joints......do they come ready lubricated or do i need to ad lubrication?
If i need to lubricated them, do i use grease and what grease gun do i need?


The Panhard bush set sleeve seems a bit long or is the sleeve ment to be slightly longer than both bushes when in place?


Do i need to grind the panhard sleeve so it's flush with the bushes?

Thank you for any help.....i always need it...lol

Might be stupid questions but i can't find the answer in the search bar:

See above post please.
