Lexus 48231-0E040 Spring, Coil, Rear

If the struts or coil springs exhibit signs of wear such as leaking fluid, loss of damping capability, or physical damage, explore all options before beginning any work. The strut/shock absorber assemblies are not serviceable and must be replaced if a problem develops. Strut assemblies complete with springs may be available on an exchange basis, which can save time and effort. Always check the cost and availability of parts before disassembling your vehicle.

It's a good idea to have the rear alignment checked and, if necessary, adjusted.
