Once you have the manual open, the first section focuses on inventory. The BR 3021 kit should include: br 3021 shock manual

While BR 3021 is a specific naval shock manual, it is often used in conjunction with other international and defense standards to ensure full survivability: MIL-S-901D : The U.S. equivalent for high-impact shock testing. STANAG 4142/4549 : NATO standards for shock resistance analysis and testing. [ SOFT / STREET ] [ HARD /

Locate the upper and lower mounting bolts. Spray all threads with penetrating oil and allow it to soak for five minutes. Support the lower axle or control arm with your floor jack to prevent it from dropping suddenly when the shock is freed. Unbolt the upper mount first, followed by the lower mount. Slide the old shock out of its mounting brackets. Step 3: Preparing the BR 3021 STANAG 4142/4549 : NATO standards for shock resistance

Inspect shock bodies for fluid leaks. Wipe down the chrome piston rod with a clean microfiber cloth to remove road grit, salt, and debris. Check that mounting bolts remain tight.

Reinstall the wheel and hand-tighten the lug nuts. Raise the vehicle slightly off the jack stands, remove the stands, and lower the vehicle completely to the ground. Bounce the suspension a few times to settle the chassis. Use your torque wrench to tighten the upper and lower BR 3021 mounting fasteners to , or to your specific vehicle chassis manual specifications. Finally, torque your wheel lug nuts in a star pattern to the vehicle's factory specification. Maintenance and Inspection Checklist
