1972 Porsche 914Repair and Restoration - Part 15 - Rear Suspension3/15/2009I was working on something else on the car, but Denver wanted to help so I figured he could help me take apart the rear suspension arm. The timing is not too bad as I am currently researching hub, stub axel, CV joint, drive shaft, transmission flange combinations for my 5-lug conversion. I also am doing some research on 911 e-brake setup
The blue monster is missing some front teeth! I also think the "one size fits all" gloves are a bit big.
Ready to take apart.
Learning how to use a ratchet. He used the impact wrench for the first time a few minute early. 5/25/2009In preparation for the modifications to install the 911 parking brakes, I examined my two rear swing arms and noticed an odd difference. The one on the left is the driver side arm and the one on the right is the passenger. Note that the driver side has an extra "tang" that doesn't appear on the passenger side. Also the tang that the hard/soft brake lines mount is different. The driver side is an enclosed hole while the passenger side has a slotted hole. I have been told that the one with the enclosed hole is an early swing arm and the one with the slotted hole is a later swing arm. Assuming you are not looking for an exact match for a specific year, the later arm is the preferred arm as it allows you to remove the caliper and hard line without breaking the connection to the soft brake line. Why is the a good thing? I believe that with the 911 rear calipers in place you actually have to remove the caliper to change pads. This is because the pins that hold the pads in place exit from the caliper in a direction that would hit the swing arms. So you have to remove the caliper, then the pins, then the pads. Being able to do this without breaking the brake line connection allows you to do this without having to bleed the brakes extensively when you change pads.
