Show me your rear

Get those arches cleaned before you put the wheels back on MM :poke:

Some serious engineering going on there :thumbsup:

Not sure I'm so keen on the inside-ass look though :lol:
 
Yes, cleaned up by glass bead blasting and wire brush on an angle grinder (the trailing arms, due to the bearings not done in glass beading) and some painting.

Especially something like the aluminium control arms or the diff (cover) can get nice when glass beading:

And nice to have 100% new bushings.

The inside of the trailing arms need a real good coat. They are continiously under attack from debris coming from the tyres. 5 months after painting the paint was gone and it started to rust again. Not that that's technical a problem (thick iron cast arms), but not so clean. So partly cleaned/painted again and sealed with a few thick layers of tectyl clear. See how long that holds. (did some (cold) iron black oxide conversion too)
The trailing arms are definately the least elegant designed pieces of the suspension. Heavy too that cast iron. Too bad there is no aftermarket solution for that (less weight, better materials etc). That's were you see that the suspension is basically a family sedan suspension. You won't find such a made suspension arm on a lotus or so.

And I saw a rear with the naked impact bar here too on a picture. With the all to common rust (Most will have that too (especially when not manical garaged), you can check it if you open de hole for the tow eye).
Did that too:

^Show your rear diversity antenna :lol:
 
O I have been busy with the bead blaster today in my lunch brake. And painting when I got home tonight pictures in my thread tomorrow. I am doing almost step for step what you have done guidok :thumbsup: thanks for the pictures good for us all to see :thumbsup:

Have you thought about hard anodizing these aluminum parts?
Click to expand...

I wouldn't hard anodize, just regular. But this cast aluminium is from a really cheap alloy (and I mean really cheap). That is very difficult to anodize and get a nice finish. The casting is both porous as irregular in mix and has probably a high content of silica, zinc, etc. You can even see the inconsistencies in the alloy (patches where the alloy has a different mix) on the parts that I've bead blasted. Areas with different colour.

There is a big chance that you get dark spots etc and ample extra corrosion protection.

I'm hoping that the impacting effect of the glass beading has some effect on the surface getting a bit more dense and be less effected by corrosion. It has a nice smooth satin finish to it, unlike a fresh casting where you can sometimes feel the crystal texture.
If you anodize you loose this effect as you're basically etching.
But my car sits in a garage overnight and is hardly used in the winter so future corrosion probably won't be a big deal.
 
Its not uncommon on car and bike parts REALLY cheap castings. People have asked me to weld parts before and you just cant due to the high levels of impurities.

I just settled with sand blasting and then a coat of silver paint.
