De cac your de dion
Good evening Gentlemen
I am in the process of renovating a sierra lsd including rear disk brakes.
As a matter of course I am replacing the wheel bearings and seals and the disks and pads etc. This still leaves the renovation of two 15 year old half
shafts, a shite coverd diff and cac encrusted brake callipers!
Whats the best way to bring these components back to new..ish condition?
Thanks for your help

"THE TOOL"
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

What he said. It was made for de cacking stuff. But as mentioned elsewhere, make sure you do it outside so as not to cover one's garage with
said cack.
Cack is good actually, the greasy cack on our diff actually stopped the bolt heads from rusting.
It just made our cortina uprights all shiney 
Not quite sure how to get the seals out of the hubs though, they seem quite firmly wedged and i don't want to destroy them. Any hints?

"The Tool" is basically a twisted wire wheel that fits onto angle grinders. You can get cup shaped ones also. Halfords do them for a
tenner.

what’s "the tool" or is that just a term for elbow grease?
I can’t see any way in which you can remove the oil/dust seals without destroying them. Incidentally if you order a bearing kit from your local motor
factor you get in the kit not only bearings and seals but also a new hub nut as well!

See above! 
If I'd got round to uploading my pictures I'd show you how succesful it is- maybe tonight!
I wouldn't use it on your ali diff casing though as it tends to massacre the soft ali with the wire brushes.
Cheers,
James

Thanks for the advice
I think i know what you mean ... a steel disk loaded with steel wire dreadlocks..!
But what do you coat the cleaned surfaces with, Surely not Hammerite?
Cheers

Having paraffin'd, 'Tooled' and then just before painting degreased with celly thinners, I've painted mine with
Plastikote's Red Oxide (couple of coats) and then a couple of coats of Plastikote's black enamel.
It all looks lovely but as my car isn't on the road I've no idea of the durability!
People of here are very rude about Hammerite, and certainly a guy I know from college who put it on his chassis managed to make an awful job of it.
On the other hand I was in a specialist paint shop the other day and the guy said he and his grass tracking friends swore by Hammerite. I suggested
people here said it was now called Hammershite and he reckoned they just weren't preparing the metal properly first.
So, who knows!

I used Hammerite on my chassis, and it's chipped on the engine bay.
But, as I mentioned in a posting on same subject several months ago, most things would when having 200kgs of eng/box bouncing off it.
Quick tip which worked for me, brush on first, then when nearly dry, put on a couple of coats with aerosol.
Worked at treat.
