How to Replace Rear Shocks & Front Struts on a 2018 Kia Soul (DIY Guide)
Step-by-step instructions with required tools, parts list, safety tips, and torque specs for shocks/struts


đź”§ Soul - Shock Absorber Replacement
On your Soul, the rear suspension uses separate shock absorbers, while the front uses strut assemblies (a strut is a shock + spring together). Replacing worn shocks/struts restores ride control, reduces bouncing, and improves braking stability.
Difficulty Level: Intermediate | Estimated Time: Rear: 1.0–2.0 hours (both sides) | Front struts: 3.0–5.0 hours (both sides)
⚠️ Safety & Precautions
- 🛑 Never work under a car supported only by a jack—always use jack stands on solid, level ground.
- 🛞 Chock the wheels that stay on the ground with wheel chocks.
- 🔥 Suspension bolts can be tight—keep hands clear if a tool slips.
- 🧷 If you’re doing front struts, the coil spring is stored energy—use a coil spring compressor (a tool that safely compresses the spring before disassembly).
- đź”§ After front strut replacement, you should get a wheel alignment.
đź”§ Required Tools
You'll need the following tools for this repair:
- Floor jack (rated 2-ton minimum)
- Jack stands (rated 2-ton minimum, pair)

🔨 Step-by-Step Instructions
Follow these steps in order:
REAR SHOCKS (most common “shock absorber” job)
Step 1: Lift and secure the rear
- Chock the front wheels using wheel chocks.
- Lift the rear using a floor jack at the rear center jack point.
- Place jack stands under the rear side support points and lower the car onto them.
- Remove both rear wheels using a 21mm socket.
Step 2: Support the rear suspension arm
- Place the floor jack lightly under the rear suspension arm (near the shock lower mount) to hold it up.
- Tip: This prevents the bolt from binding.
Step 3: Remove the rear shock lower bolt
- Use a 17mm socket and breaker bar to remove the lower shock bolt.
- If the bolt is tight, use a pry bar to slightly line up the holes while turning the bolt out.
Step 4: Remove the rear shock upper nuts
- Open the rear hatch.
- Remove the rear cargo floor and side trim panels enough to access the shock towers using a trim clip tool.
- Use a 14mm socket to remove the two upper nuts for that shock.
Step 5: Remove the shock and install the new one
- Pull the old shock out from below.
- Position the new shock in place.
- Start the upper nuts by hand using a 14mm socket (do not fully tighten yet).
- Raise/lower the suspension arm slightly with the floor jack to align the lower bolt hole.
- Install the lower bolt using a 17mm socket.
Step 6: Torque the rear shock hardware
- Torque the rear shock upper nuts using a torque wrench and 14mm socket: Torque to 44 Nm (32 ft-lbs).
- Torque the rear shock lower bolt using a torque wrench and 17mm socket: Torque to 98 Nm (72 ft-lbs).
Step 7: Reassemble interior trim and wheels
- Reinstall the interior trim and clips by hand, then press them in fully.
- Reinstall wheels using a 21mm socket.
- Lower the vehicle and torque lug nuts using a torque wrench: Torque to 88–108 Nm (65–80 ft-lbs).
FRONT “SHOCKS” (these are struts on your Soul)
Step 8: Mark camber position before disassembly
- With the front wheel off, use a paint marker to mark the strut-to-knuckle bolt positions.
- Tip: Marks help keep alignment close.
Step 9: Disconnect the sway bar end link (if attached to strut)
- Use a 17mm wrench and 17mm socket to remove the end link nut.
- If the stud spins, hold it with a wrench while turning the nut.
Step 10: Remove strut-to-knuckle bolts
- Support the steering knuckle with the floor jack so it doesn’t drop and stress the axle.
- Remove the two large bolts/nuts using a 19mm socket, 19mm wrench, and breaker bar.
- Torque on install later: Torque to 156 Nm (115 ft-lbs).
Step 11: Remove the strut top nuts and remove the strut
- Open the hood.
- Remove the strut mount nuts using a 14mm socket (leave one nut loosely started until you’re holding the strut).
- Remove the strut assembly from the wheel well.
- On install: Torque the strut mount nuts to 44 Nm (32 ft-lbs).
Step 12: If reusing springs, transfer spring to new strut
- Install the coil spring compressor (specialty) on the spring and compress evenly until the spring is loose in the seats.
- Remove the center shaft nut using a pass-through strut nut socket set (specialty).
- Move the spring and mount onto the new strut in the same orientation.
- Release the spring compressor slowly and evenly.
Step 13: Reinstall front strut and torque fasteners
- Install the strut into the tower and start the top nuts using a 14mm socket.
- Attach the knuckle to the strut and install the two bolts/nuts using a 19mm socket and 19mm wrench.
- Torque strut-to-knuckle bolts using a torque wrench: Torque to 156 Nm (115 ft-lbs).
- Torque sway bar end link nut using a torque wrench and 17mm socket: Torque to 88 Nm (65 ft-lbs).
- Torque strut mount nuts using a torque wrench and 14mm socket: Torque to 44 Nm (32 ft-lbs).
âś… After Repair
- Do a short test drive on a smooth road. Listen for clunks over small bumps.
- Recheck for any loose hardware if you hear noise.
- If you replaced front struts, schedule a 4-wheel alignment as soon as possible.
- Re-torque lug nuts after 50–100 km using a torque wrench: 88–108 Nm (65–80 ft-lbs).
đź’° DIY vs Shop Cost
Shop Cost: ₹8,000–₹18,000 (rear shocks pair) | ₹18,000–₹40,000 (front struts pair + alignment)
DIY Cost: ₹3,500–₹10,000 (rear shocks pair) | ₹10,000–₹28,000 (front struts pair, parts only)
You Save: ₹4,000–₹12,000 (rear) | ₹6,000–₹15,000 (front) by doing it yourself!
Shop labor rates vary but typically run ₹800–₹2,000/hour. This repair takes a shop approximately 1–2 hours (rear) or 3–5 hours (front).
