control arm question

[JenTay]

in reading earlier posts, i'm a little fuzzy on what to do.

to remove the front lower control arm, do i need to compress the spring somehow? i borrowed a spring compressor that mainly consists of two rods with claws on each end to compress the spring. the car is sitting on blocks now with spring in the 'relaxed' position. i'm afraid that if i unbolt the inner bolt there might still be enough energy in the spring to cause an accident.

thanks in advance guys.
