When I was rebuilding the rear subframe I bought a proper greasing gun for the rear arm shafts. However, I heard a pop on both sides while squeezing the grease in. Anyway, those plastic inserts are useless so I bought some (expensive) stainless steel ones from Japan. I don't want to have to put 1/2 a litre of grease into each arm to ensure that grease gets to the brass bush.

The new plastic insert...split

Stainless steel replacement...

After reinstalling the rear arm bearing and testing the grease pressure, I shaped and installed the swing arm brake lines.

Reassembled arms back in the subframe with the rear subframe brake lines installed.

The only thing missing from the rear subframe is the hand brake cable and the quadrants for the arms. Will need to investigate some nickel zinc electroplating for this.

Does the larger repair piece help with heat dispersion?

Front subframe looks pretty good, nice smooth bends, done by hand or tool?

Yes the extra metal helps to pull the heat away. If the piece was the exact size it would warp really badly.

I used a cheap 15 euro pipe bending tool to make the bends. However the length of tubing came as a circular coil that I had to straighten first by hand.

I did not know that woody. Thanks for the heads up. Luckily it was just a loose fit for now and I hadn’t tightened everything up because the hoses need to go into the brake calipers first before tightening the nut on the subframe.

Repairing the straight part on the bottom of the door. It's actually curved so I had to make a few slits to get the repair piece to match the contours.

Image

Image

Just tacked up for now. I will finish over the coming days ... long enough weld to complete.

Patience, patience and patience. Welding up this section took a couple of hours in order to prevent warping

Image

Still need to knock down the tops of the welds on the inside. Nothing major just to make it tidy given it will be hidden inside the door.

Clean up the inside so you can get a good seal of paint on it. Doors tend to rust from the inside out. Great work your doing.

Yes agree woody. There is excellent penetration of the weld from underneath and given this inside area will get a lot of water, the flatter the area the better. I am planning on epoxying the door frame and skin before they are assembled.

I also identified the ‘sided’ braided hoses on the front subframe. Turns out I put them on the correct side. There are deeper internal threads on the drivers side.

Put the passenger door frame back on and offered up the outer skin. Lines up nicely and I have used a couple of cleco clamps where I plan to put a plug weld to hold the position.

Image

It will help aid the alignment when I remove the quarter panel.

Thanks Colin. Takes quite a while to get used to the welder and finding the right settings for specific types of welds. I am going to keep going on the boot and driver's door while it's all going well.

All welded up

Image

Straight forward grinding down weld on an outside curve

Image

Touch etch to protect

Image

Inside came up well too

Image

A bit faster this time. It took 1h 45m to weld, grind and etch.
