How to Replace a Broken Coil Spring

Here's how to replace a broken front or rear coil spring on your car!



Coil springs on your car can snap or fail due to corrosion, overload or fatigue stresses over time. They can also sag causing suspension to bottom out.



In this video, the rear coil spring is replaced on a Toyota Sienna which should be the same procedure for any vehicle with a torsion beam rear suspension. The front coil spring is replaced on a Toyota Camry, which should be the same procedure for any vehicle with a McPherson strut suspension.



The rear coil must be slightly compressed with a jack before the shock can be disconnected. The torsion beam is then lowered on both sides, allowing the spring to fall out. On some models (such as AWD), spring compressors may need to be used as there isn't enough room when the torsion beam has pivoted out of the way. When installing, the coil is to be seated at the top first, and then slipped in the bottom, with someone putting pressure to force the torsion beam down. Take note that the spring sits in its correct seat and orientation.



The front coils are pretensioned and held on with the strut mount nut. Spring compressors must be used to squeeze the spring and take the tension off the mount before removing. When assembling, replace the bump stop, boot, bearing, mount or strut if worn. Take note of the spring, mount and upper spring seat orientation.
