You can Select Your Vehicle to check if BR3Z-18125-C fits your vehicle.

Raising the axle so that the shock compresses to the reference mark simulates the position of the vehicle's suspension when it's sitting at normal ride height, ensuring proper shock absorber installation.

To reassemble the strut assembly, the rubber bumper and dust cover should be installed. The coil spring should be placed onto the strut, ensuring correct positioning onto the lower spring seat. The upper bearing assembly should be installed, aligning the notch on the bearing assembly with the clevis on the bottom of the strut. The damper rod nut should be installed and tightened to the specified torque. Finally, the spring compressor tool can be removed, and the strut/spring assembly can be installed.

Mark the positions of the bolt heads.

If you suspect worn or weak shock absorbers, repeat the check at each of the three remaining corners of the vehicle. Additionally, raise the vehicle and support it securely on jackstands to inspect the shock absorbers for evidence of fluid leakage. Some light film of fluid is generally not a cause for concern, but if significant leakage is noticed, it's advisable to replace the shocks as a set. Ensure that the leakage is from the shocks and not another source. Check the shocks to make sure they are securely mounted and undamaged. Also, inspect the upper mounts for damage and wear.
