I am restoring a 68 AMX, came in boxes, so I have I no references to the way it was. I installed the coils, strut rods and trunnions over the weekend, the engine , trans etc all out of the car.
Is it normal to have the control arms dropped to the Max, the upper control arms are resting on the frame rails. I’m sure once the power train gets in , Suspension will drop, but want to make sure I have not missed a crucial step . I did notice with all dropped I can’t get the shocks in , do to the angle of the truant coils. Again is this normal. Any advice is appreciated. Thanks |

No. The engine and transmission were out of the car when I restored the front suspension. Here is another photo of when the engine was out.

If it helps any, with my 68 Amx currently sitting on the hoist the upper arms are also resting on the 'frame' with the suspension dangling (no shocks currently installed, if it matters).

Thanks , I wonder if the shocks are enough to old it up off the frame . With the angle of the coils at the moment I can’t even get the shocks in place.

I don't understand the mystery here -- the springs will extend to their fullest-possible length and press the suspension components down to maximum extension. That's what springs do.
The shock, if installed, will restrain total extension, that's what happens when you use a bumper jack, or frame lift. It squashes the outer shock bushings awfully, but seems to do no harm, I assume for short periods (tire change, car repair). For many model/years, the TSM recommends a piece of wood (2 x 4) between upper control arm and the control arm pocket to limit travel. If there's no engine installed, you'll have to use a spring compressor to compress it. If there's an engine, you can jack the lower control arm up (block of wood under it) to compress it (watch for body lift) and get a shock in. For strut-rod cars, you usually cannot install the the strut rod with the suspension dangling like that. It's been a while, but I think the trick is to keep the spring squished, assemble strut rod loosely, and only tighten it up when the full weight of the car is on the tires and the suspension is in operating position. You have no strut rod in the photos; I personally would not drop an assembled car onto the ground (assembled with tires, etc) without the rod in place. With weight on the tire, the lower arm is under no load, but if you were to roll the car with no strut rod, that lower arm could bend at the bushing, collapse to the ground catastrophically and break parts and maybe your body.

Thanks, yes this is the first AMC car I have restored. It’s a learning experience for sure. I have installed the shocks and all is good now. Everything is the way it should be at this point. My error was not installing the shocks, at the time I did know they were the missing link I was looking for. Again I appreciate all the advice and knowledge I get from this forum.
