đź”§ Terrain - Shock Absorber Replacement

On your Terrain, the “shocks” can mean the rear shock absorbers and/or the front strut assemblies (a strut is a shock with a spring built around it). The steps, tools, and torque specs are different front vs rear, and also differ by FWD vs AWD.

Difficulty Level: Intermediate | Estimated Time: 2-6 hours


⚠️ Safety & Precautions

  • ⚠️ Support the vehicle with jack stands on the pinch welds/subframe; never rely on a jack.
  • ⚠️ Suspension parts can be under spring load; the front strut can be dangerous if disassembled without a spring compressor.
  • ⚠️ If you’re doing front struts, do not let the steering knuckle hang by the brake hose/wiring—support it.
  • ⚠️ Battery disconnect is not usually required, but keep the key away and avoid turning the steering with parts disconnected.

đź”§ 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 (22mm)
  • 1/2" drive breaker bar
  • 1/2" drive torque wrench (20–200 ft-lbs)
  • 3/8" drive ratchet
  • Socket set (10mm–24mm)
  • Wrench set (10mm–24mm)
  • Torx bit set (T20–T50)
  • Pry bar
  • Needle-nose pliers
  • Penetrating oil
  • Paint marker
  • Dead-blow hammer
  • Spring compressor (specialty)

đź“‹ Before You Begin

  • Park on level ground, set the parking brake, and chock the rear wheels.
  • Break the lug nuts loose with a 22mm socket and breaker bar before lifting.
  • Two quick questions so I give the exact steps and torque specs:
    • Are you replacing the front (struts), the rear (shocks), or all four?
    • Is your Terrain FWD or AWD?
  • Tip: If doing front struts, plan an alignment.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which end you’re replacing

  • Reply with Front, Rear, or All, and FWD or AWD.
  • Once confirmed, I’ll provide the exact step sequence and the correct torque specs for your Terrain.

Step 2: Do not disassemble a front strut without the right parts

  • If you are replacing front struts, decide whether you’re installing complete strut assemblies or reusing your springs.
  • If reusing springs, you must use a spring compressor (specialty) (it compresses the coil spring so the top nut can be removed safely).

âś… After Repair

  • Torque the wheel lug nuts with a torque wrench in a star pattern after the vehicle is on the ground.
  • Test drive slowly first; listen for clunks and recheck fasteners.
  • If you replaced front struts, get a 4-wheel alignment as soon as possible.

đź’° DIY vs Shop Cost

Shop Cost: $700-$1,800 (parts + labor, depending front/rear/all)

DIY Cost: $180-$900 (parts only, depending front/rear/all)

You Save: $520-$900 by doing it yourself!

Shop labor rates vary but typically run $100-$150/hour. This repair takes a shop approximately 2-6 hours.
