How to Replace Front Struts and Rear Shock Absorbers on a 2018 Kia Sportage
Step-by-step suspension replacement with required tools, parts list, safety tips, and alignment notes


🔧 Sportage - Shock Absorber/Strut Replacement
On your Sportage, the front suspension uses struts (shock + spring as one unit) and the rear uses shock absorbers (separate from the spring). The steps, tools, and torque specs are different front vs rear, so I want to aim you at the right procedure.
Difficulty Level: Intermediate | Estimated Time: Front: 3-5 hours (pair) / Rear: 1.5-3 hours (pair)
⚠️ Safety & Precautions
- ⚠️ Never loosen the center nut on a front strut unless the spring is safely compressed.
- ⚠️ Support the vehicle with jack stands; never rely on a floor jack alone.
- ⚠️ Keep hands clear of suspension pinch points while raising/lowering the control arm.
🔧 Required Tools
You'll need the following tools for this repair:
- Floor jack (rated 3-ton minimum)
- Jack stands (rated 3-ton minimum)
- Wheel chocks
- Lug nut socket (21mm)
- Breaker bar (1/2")
- Torque wrench (20–200 ft-lbs range)
- Socket set (10mm–22mm, 1/2")
- Wrench set (10mm–22mm)
- Pry bar (24")
- Hammer (2 lb)
- Punch set
- Penetrating oil
- Paint marker
- Needle-nose pliers
- Spring compressor (external type) (specialty)
- Safety glasses
- Mechanic gloves
🔩 Required Parts
HowToo sells all the parts you need for this repair:
- Front strut assemblies (quick-struts) - Replace in pairs - Qty: 2
- Rear shock absorbers - Replace in pairs - Qty: 2
- Front strut mount/bearing kit - If reusing springs - Qty: 2
- Self-locking suspension nuts/bolts - If specified for one-time use - Qty: 1 set
📋 Before You Begin
- Park on level ground, steering straight, and set the parking brake.
- Chock the wheels that stay on the ground.
- Loosen lug nuts with a 21mm socket before lifting.
- “Strut” = shock + spring assembly. A spring stores a lot of energy, so we either use a quick-strut (pre-assembled) or a spring compressor (a clamp tool that compresses the spring).
🔨 Step-by-Step Instructions
Follow these steps in order:
Before I list the exact steps + torque specs, answer these 2 quick questions:
- Are you replacing the front struts, the rear shocks, or all four?
- Are you installing quick-struts (complete assemblies) up front, or reusing your original springs (requires the spring compressor)?
✅ After Repair
- Plan on a 4-wheel alignment if you replace the front struts.
- Re-check lug nut torque after 25–50 miles.
