How to Replace Front Struts & Rear Shock Absorbers on a 2018 Cadillac XT5
Step-by-step DIY suspension guide with required tools, parts list, safety tips, and torque specs


🔧 XT5 - Shock Absorber Replacement
On your XT5, the rear uses separate shock absorbers, but the front typically uses a strut assembly (a strut is a shock with a spring seat built into it). The exact tools, steps, and torque specs change depending on whether you’re doing the rear shocks or the front struts.
Difficulty Level: Intermediate | Estimated Time: 2-6 hours (depends front vs rear)
⚠️ Safety & Precautions
- ⚠️ Support the XT5 on jack stands before working underneath.
- ⚠️ Never loosen a front strut/spring without a spring compressor; the spring is under heavy force.
- ⚠️ Keep hands clear when lowering/raising the suspension arm with a jack.
- ⚠️ If your XT5 has ride-control sensors/wiring near the shock/strut, unplug carefully and don’t pull on wiring.

📋 Before You Begin
- Park on level ground, set the parking brake, and chock the wheels.
- Loosen lug nuts slightly before lifting (use a breaker bar).
- Plan to replace shocks/struts in pairs (left and right) to keep handling even.
- Please answer these 2 quick questions so I can give the correct exact procedure, tool sizes, and OEM torque specs:
- ✅ Are you replacing the rear shocks, the front struts, or all four?
- ✅ Do you have AWD or FWD?
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Get the XT5 safely lifted
- Use a floor jack to lift at the proper lift point, then set it down on jack stands.
- Remove the wheel using a lug nut socket.
Step 2: Identify which setup you have (rear shock vs front strut)
- Rear: you’ll see a separate shock between the body and rear suspension arm.
- Front: you’ll see a tall strut with the coil spring wrapped around it.
Step 3: I’ll provide the exact removal/installation sequence and torque specs
- Once you reply with rear/front/all and AWD/FWD, I’ll give you the correct XT5-specific steps including:
- Which fasteners to remove first and how to support the suspension with the floor jack
- What interior trim (if any) to remove for upper mounts using a trim clip removal tool
- Torque to OEM specification for every mounting fastener
- If front struts: safe spring handling with a spring compressor (specialty) (a tool that safely squeezes the spring)
✅ After Repair
- Double-check all fasteners are tightened and all clips/wiring are resecured.
- Reinstall wheels and tighten lug nuts with a torque wrench to the wheel lug OEM spec.
- Test drive slowly for clunks/rattles, then recheck for any looseness.
- If you replaced front struts, schedule a 4-wheel alignment ASAP.
💰 DIY vs Shop Cost
Shop Cost: $500-$1,600 (parts + labor, rear vs front varies a lot)
DIY Cost: $150-$900 (parts only, depends on shocks vs complete struts)
You Save: $350-$700+ by doing it yourself!
Shop labor rates vary but typically run $100-$150/hour. This repair takes a shop approximately 2-6 hours.
