How to Replace Front & Rear Struts (Shock Absorbers) on a 2019-2021 Subaru Forester
Step-by-step DIY procedure with required tools/parts, safety tips, and alignment reminders for 2019, 2020, 2021
🔧 Forester - Shock/Strut Replacement
On your Forester, the “shock absorbers” are part of the strut assemblies (front and rear). The front and rear procedures, parts, and torque specs are different, so I need one quick confirmation before I give you exact, dealership-accurate steps.
Difficulty Level: Intermediate | Estimated Time: 2-5 hours (depending on front/rear/both)
⚠️ Safety & Precautions
- ⚠️ Never work under a vehicle supported only by a jack; use jack stands.
- ⚠️ Struts are under spring tension; a coil spring compressor can be dangerous if misused.
- ⚠️ After strut work, you will need a 4-wheel alignment to prevent tire wear and pulling.
🔧 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
- Safety glasses
- Mechanic gloves
- Breaker bar (1/2")
- Torque wrench (20-200 ft-lbs)
- Socket set (8mm-22mm)

🔨 Step-by-Step Instructions
Follow these steps in order:
Before I give the exact step-by-step with Subaru torque specs:
- Are you replacing the front struts, the rear struts, or all four?
- Are you installing complete quick-strut assemblies (strut + spring + mount) or reusing your springs (requires a spring compressor)?
Tell me those two details and I’ll send the exact numbered procedure with correct torque specs.
✅ After Repair
- 🛞 Get a 4-wheel alignment as soon as possible.
- 🔎 Test drive at low speed first; listen for clunks over bumps.
- 🧾 Re-check lug nut torque after ~25-50 miles.
💰 DIY vs Shop Cost
Shop Cost: $900-$2,200 (parts + labor, front/rear/both)
