An interesting read and great work - wish I had the space and necessary tools to have a go at some of the work you are doing - you are going to feel a vast improvement when all is done and you go for the first test drive - good luck with the rest of the project!

Steve well done mate your doing a great job there, I done the exact same job last year ,and the back end off your z will feel kind off new when finished,iff uve not refitted the new diff bush which isn't truly round,can be tricky without a hydraulic bench press , but can be done done with a large vice and a few swear words along the way.but no pain no gain , Stella job ure doing there!
Thanks Jimmy. I have a Powerflex bush on the diff - you can't quite see it in the photo.

Some great work Steve, are you painting the Diff. itself? Also what are you doing with the brake back plates, cleaning and painting when the axle is back on the car? IF the back plates need changing due to corrosion (of the holes where the shoe hold down pins fit) now would be the time to do it.

Tony.
I'm not painting the diff Tony. I've just put Hammerite on the pressed steel bits to protect them a bit. Yes, I'll be having a look at the back plates when back on the car. Unfortunately with the axle down, they do get a little mistreated even with wood blocks under the hubs.

Yes. I've used polybushes everywhere else, combination of Super Pro and Powerflex, but I have standard rubber bushes for the sub-frame. I'll have to find someone local to press them in for me.
Hi Steve, Out of interest for me attempting to do the same why did you use a mix of Super Pro and Powerflex?

Just how it worked out really. Think I prefer Powerflex which in some instances are easier to fit with the bush being in two halves rather than one piece SuperPro.

I'm waiting on a couple of new brake lines at the moment so progress reports will resume after Easter hopefully. :)

Well that was a long wait I'm afraid. Knowing that I'm useless at making bubble flairs on brake lines, I had ordered a set of lines ready made via Ebay. Unfortunately they had been made to the 'ABS' pattern and not the 'ASC+T' pattern which meant that the main lines from front to rear were wrong. The replacements arrived yesterday and so I was able to get back to work in the afternoon. First job was to duplicate the lines which is so much easier if you can remove the old ones intact.

This is the new line bent and taped beside the old one to get it as accurate as possible. It doesn't have to be absolutely identical but should be as close as possible. Below is one for a trailing arm.

I had to buy a new tool. My old bending tool at the top of the photo bends OK but its hard to accurately place the bend along the pipe. The new blue tool is fiddly to use but you can accurately position the bends. Anything less that 90 degrees is easier using just fingers though I found.

I did make one cockup:

The left and right rear lines have different sized nuts at the ABS unit so that you don't switch them by accident. I hadn't noticed this and so had to swop nuts and re-make the flair (after a couple of practice goes.

So today, the rear sub-frame/axle was refitted to the car using two trolley jacks, the car jack and several large blocks of wood. It went OK but would be easier with two people!

Today's problem was a bit unexpected - I bought a Pagid handbrake cable to replace the one I had to cut and drift out, but the end diameter is about half a mm too large for the hole in the back plate. Serial numbers all seem to be correct so I don't know what's amiss. I may go and buy another make cable tomorrow and return the Pagid one as I don't want to be held up by this.

So glad I've watched this thread, I didn't know about the different sets of lines and was about to order the same from eBay! I've got ASC so I presume I need to make sure I don't order ABS ones?

Mine came from 'Classic Car Geek' I don't know where he gets the technical data from but Real OEM shows 3 different brake pipe arrangements for my car but only ASC+T is correct and even then, the length of one of the main lines isn't listed so I had to measure it with string.

Cheers, the seller I'm watching clearly state you have to supply reg or numbers from the VIN to ensure the correct one is supplied - we'll see!

I fitted Pagid cables on my Z3 Steve, got them from ECP. I ended up just enlarging the holes in the back plate.

If you go slightly oversize just put some gasket silicon on the steel piece as you fit it into the back plate. Will stop any chance of a rattle.

Tony.
