A Part That Fails Quietly, Then Suddenly
Months of gradual sagging with barely any symptom beyond a marginally lower ride height is the usual pattern for the Lexus RX's rear spring, right up until it fails suddenly at the coil's end with a clunk. If one rear corner looks lower than the other, that's the clue worth acting on.
Lexus RX Rear Springs: OEM Part Number
| Petrol/non-hybrid, standard rate | Genuinely a different spring from the hybrid version below — confirm powertrain and side before ordering |
|---|---|
| Hybrid | A genuinely different spring rate from the non-hybrid version, reflecting the different weight distribution of the hybrid drivetrain |
| F Sport, where fitted | A genuinely different, stiffer spring from standard trims |
Replacing just one Lexus RX 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.
Lexus RX Rear Springs: What It Does
The Lexus RX'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.
