Post subject:  Rear sway arms sectioned

I was doing some work swapping stub axles so I thought I'd cut up a trailing arm to show everyone what their car is made out of.
Complete arm;
Image
Stub axle pressed out. If you look closely you'll see a cir-clip on the shock mount side. My guess is this is to stop the stub axle getting pulled through over time.
Image
The cuts are along the casting seams and straight in through the top to give a good idea on the thickness of the walls.
Image
You can see it's hollow right up into the stub axle and the pivoting pin sits inside a steel tube to separate it from the hollow space and to prevent the grease from "draining" away from the needle roller bearings.
Image
So imagine how heavy they would be if they were solid :shock:

Which is what often happens with the `steel tube' replacements- they are now thin cheap plastic and do not fit well.
If yours has the steel tube, try and keep it.

Interesting that, because i have pumped lots of grease into them before any came out. It looks as if the handbrake quadrant pivot is isolated too.

Makes me wonder if there were different castings where the grease just went everywhere.

I'm not sure about the handbrake because this one dose look sealed off but I've had some arms that I've cleaned up and it seems like grease just keeps coming out of those dam holes :? I might cut that open one day and see for sure.
