A customer writes in to ask why their new coil springs fall out so easily during installation. Coil springs that have been in a car for a long time accumulate all sorts of cruft and debris that eventually sticks it in place.
My new coil springs are falling out, is this normal?Ask The Spring Guru
On most rear straight axle cars, the coil springs simply sit on a mounting surface with nothing to hold the springs to the axle except for the weight of the vehicle.
This is the way they were built right out of the factory. Over time, road debris and temperature changes cause the springs to bond by the way of junk and rust to both the upper and lower mounting plates.
When the spring has changed, you have to work at getting them out, and if the suspension uses a rubber isolator pad between the spring and the mounting plates, the amount of effort required to get them out could be multiplying many times over.
Once the new springs are installed, the shocks reattached, and the weight on the springs, you won’t have to worry about if they will fall out.
