multiple rear axle problems!!

[fax0815]

Hi,
I finally got time to install all my parts!

But there are some problems, and I´d like to have a few opinions :

This was taken last year, eversince I bought all new bearings and a solid spacer and it will get a complete new allignement, done by specialist.
Does a TRD diff get the same settings as a stock unit?

C/P gear doesn´t look to bad, so this should cure the problem (at least become less noisy)?

Another problem with the wheelbearings.
I bought a slidehammer to get them out, but I could pull the left axles with a slight tap, an the other one by hand!
Aren´t they supposed to be fu**** tight in there?
One bearing has play and rusty stuff comming out of it, so i needs replacing, the other one seems fine, but I think I´ll replace it, too just to make sure it is fine.
I´ll use some loctite shrink disc connection to get it a little tighter in there.

What you think?
