Stupid question, but how can you replace the upper control arm/balljoint without the spring compressor. Doesn't the control arm hold everything in place, and therefore the spring would let loose if you unbolted the upper balljoint?

I did once see my mechanic remove the outer spindle without the compressor, stating that the shock would hold the lower control arm in place and hence keep the spring in place, but I thought it was risky, and went back into the waiting room!
