Removing rear hub

[allegoricus]

I'm most of the way through removing the rear hub (a job that started because the protective plate needs replacing) and find I can't free the hub from one of the arms to which it's attached.

First picture shows where I'm at, with the connection to the problem arm in the centre:

Will it be easier to detach this arm at the other end? Or is there a simple approach that has thus far eluded me?

TIA,

Peter

This is clearer, althouogh without as much context:

just hit it hard.

Theres a post on here somewhere with a two hammer method.

Thanks for this. Sorry to be obtuse but I'm not sure what I should be expecting as the outcome here. Is the ball joint supposed to pop out from the end of the arm, or should the bolt through the casting come free?? If it's the ball joint, can it be re-inserted or, having been removed, does it need to be routinely replaced?
It's not quite clear from the clip just where the blows are meant to land.
Sorry, but I'm venturing into uncharted territory, and running into things that puzzle me as to why they have to be so difficult.

the thread will come free leaving a hole where the thread was in

hit it or use a balljoint splitter to seperate. if the balljoint is OK then no need to replace it, but if you use a tool to seperate make sure you dont kink the rubber boot.

OK, the latest round of monster wellying has resulted in success, and all is now clear.
Thanks all. Now to get the bearing out ...

I have just replaced the rear offside backplate on my W203. I took the advice of an Indie and cut it in half, avoiding the need to take the hub off.

It was a quick and easy job. I cut it at the narrow point (near the caliper mounting), through one of the retaining bolt holes. In the other other side I cut through the piece where the parking brake cable goes through.

It is then easy to fit, and if you put a decent sized washer over the hole that was cut through, it goes on and stays firm (two and a half bolts holding each part). Difficult to explain, but easy if you have a retaining plate in front of you.

I know what you mean but, for this project, it's too late.
Thanks for chipping in, though.
