Rear suspension build
Posted by: kaminski45 ()

I am going to begin putting back together my rear suspension on my 64. What is the best way to keep the spring compressed enough to get the shock in? I am doing this out of the car.

I did mine on the benchtop and used a threaded rod to compress the spring, then ratchet straps hold it in place so I could remove the threaded rod and install the shock. Probably not the safest way so be careful please.
When I disassembled the rear suspension from my donor car I positioned the rear crossmember in my hydraulic press, likely safer but was a bit more work to get it in position.

'64 springs are softer [40%] than 60-63's

A ratchet strap should do it...

REMEMBER to put the LONG spring on the DRIVERS side..

The threaded screw seems much safer. Once you put the spindle on, everything is restrained. I guess the straps might be ok, but I wouldn't use them.
All-thread is pretty cheap and easy.
I sure wouldn't leave the spring in there and compressed with only straps holding it.

Remember the threaded rod must come out in order to install the shock. So the threaded rod was used to compress the spring, the straps used to hold it compressed while the rod was removed for shock install.

I recently installed early rear springs while doing complete suspension rebuild. I put the crossmember in the car with the car on my lift. I used a tall support jack stand made for under lift use and by lowering the car with the stand supporting the lower arm was able to get it them compressed to within 1" of shock install. I had my wife come out and hang (think monkey bars) on the rear body crossmember, which compressed the spring just enough more to allow top shock nut install. This would not have been necessary if the powertrain was in the car as its weight would make the spring compress enough to install the shock.
