It's on wheels!!!

Yes, it's now on it's wheels. After a big push towards getting a lot of work done, Dad and I got the brakes bled, the diff and half-shafts installed, and the front suspension sorted out. This means that after a weeks work, the car car be pushed around!

First, the breakes. We bled all the brakes, so now there's pressure in the system and the brakes all work. I did stuff one up, and threaded one of my front calipers, which was a problem. Frank helicoiled the caliper and all was well, but as a mental not I'll watch that one for any leakage for the first few hundred km's.

With a few minor leaks sorted out, this was over pretty quickly, especially as a tag team. Bleeding brakes is a two person job.

Getting the diff in was fun, although luckily with the small and light Subaru diff, this could be done with all of the backplate in place, whereas the Sierra diff requires the backend to be largely dismantled to get it in. So we manouevered it into place, bolted it up, and it was ready for the halfshafts.

These went in without a hitch, although it's sobering to realise that the entire power transfer from the diff to each halfshaft is controlled by six small bolts on each shaft. Still the diff holds the prop shaft with four bolts, so I guess it's all OK. Someone must have done the maths somewhere.

Anyway, with that all done, all it took was bolting the wheels on, and getting a crane out to lift the car off it's frame and onto the floor, where it sits today. Again, lots of photos, but I'll upload these later.

I did have to come in the day after and tighten up some bolts on the rear uprights, as in the excitement we had completely forgotten to do any of these up beyond a few threads. So I took each wheel off and put these on properly (but not to final tightness). So I could take the Christmas / New Years break without worrying that the backend would fall off.
