What should I do to the diff? Just paint it or replace seals etc?
As above really.
I bought my Sierra diff off e-bay so I've no idea how good or otherwise it is.
So far I've gleaned it up with a wire brush and was going to spray it silver rather than try to get a decent finish on the casting.
Is that all I need to do or should I take the back cover off and clean it out and possibly replace the oil seals?
John.

Don't even paint it, its ali, so just leave as it is...
If it turns nicely, I wouldn't do anything else personally...

I painted mine with silver engine lacquer, looks very nice and easier to clean than the bare metal

If its got oil in it and the seals aren't leaking I'd just replace the oil, and not risk creating a leak by disturbing the seals.

Is it worth getting a more expensive lightweight oil from the likes of Redline in order to reduce transmission losses, or do most folk opt for the
standard oil?

I've used Redline superlightweight oil. Smells gorgeous!! I get a tiny bit of crunching when taking off the pre-load (ie if I've rolled
backwards then get the clutch to the biting point again). Not sure if that's the diff being a bit work, normal sounds when running without a
cush-drive or due to the superlightweight stuff. I've bought some non-super lightweight stuff to dry instead.
Personally I just wire-brushed mine and sprayed it black with hammerite. that was 5 years ago and it still looks like new. It's not necessary to
do but makes the diff look a bit nicer.
Wouldn't personally bother replacing the seals unless it looks like it's been leaking....

I'm going to replace the half shaft seals but not the pinion one.
Is there anywhere you can buy the halfshaft seals in a set without having to buy the pinion seal too?

Personaly I wouldn't bother mate, unless the diff is really shagged it's very unusual for the seals to leak. I have fitted two to my car
and neither have leaked, and one was worn out, wining and cluncking. Just my two cents worth. HTH Ray

You could have done it in less time that was taken to read all this whining and work dodging.
Don't listen to the lazy gypos who are happy to sling a lump of cow sheit under their car. Pressure wash it, wire brush it and paint it, The oil
seals are 43 x 62 x 12/8 - tap them in with a socket or bit of pipe. Available from Brammer (was BSL) or any other bearing stockist. Then change the
oil - EP80/90.
