Left and Right Are Genuinely Separate Parts — Confirmed by Toyota's Own Catalogue
Genuinely worth knowing: Toyota's own parts catalogue lists rear coil springs as lower-left and lower-right references — distinct, non-interchangeable parts rather than a single spring fitted to either side.
Toyota Avensis Rear Springs: A Part That Fails Quietly, Then Suddenly
A rear spring often sags gradually for months without an obvious symptom beyond a slightly lower ride height, then fails suddenly at the coil's end with an audible clunk — worth bearing in mind if you notice one rear corner sitting lower than the other. Toyota's own guidance notes that coil springs aren't especially prone to failure under normal use, but cutting, clamping, or heating a spring genuinely compromises it and can lead to premature failure.

Replacing just one Toyota Avensis rear spring is a false economy: pairing it with an old, sagged spring on the other side produces uneven ride height and a noticeable handling bias.
Toyota Avensis Rear Springs: What It Does
The Toyota Avensis's rear end weight rests on the coil spring, which also absorbs the initial shock of a bump — a separate function from the shock absorber, not a replacement for it. Left sagged or broken, it lowers ride height, potentially skews headlight aim, and can become an MOT failure in severe cases.
