🔧 Tacoma - Shock Absorber Replacement

You’ll be replacing the front coilover assemblies and rear shock absorbers on your Tacoma to restore ride comfort and control. We’ll focus on using “complete assemblies” up front so you don’t have to compress coil springs, which is much safer for a beginner.

Difficulty Level: Intermediate | Estimated Time: 4-6 hours (all four corners)

⚠️ Safety & Precautions

• ⚠️ Never work under the truck supported only by a jack. Always use jack stands under solid frame points.
• ⚠️ Coil springs store a lot of energy. This guide assumes you install complete front coilover assemblies so you do not need a spring compressor.
• ⚠️ Chock the wheels (block them) so the truck cannot roll while lifted.
• ⚠️ Suspension parts are heavy; support them with a jack to avoid pinched fingers or strained bolts.
• ⚠️ If you have aftermarket lift or leveling parts, torque specs may not match—recheck with the kit instructions.
• ⚠️ No battery disconnect is required for this job.

📋 Before You Begin

• Park your Tacoma on level, solid ground. Put the transmission in gear and set the parking brake.
• Place wheel chocks behind the rear tires when working on the front, and in front of the front tires when working on the rear.
• Loosen (do not remove) the wheel lug nuts 1/2 turn with the truck still on the ground.
• Plan to do both front shocks together and both rears together. Always replace shocks in pairs.
• After this job, schedule a 4-wheel alignment; changing front shocks affects alignment.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and Support the Front of the Truck

• Spray penetrating oil on front shock bolts and nuts (upper and lower) using the penetrating oil spray. Let it soak a few minutes.
• Use the floor jack (3-ton) under the front frame crossmember to lift the front until both front wheels are off the ground.
• Place jack stands (3-ton) under the frame rails behind the front wheels on both sides. Slowly lower the truck onto the stands.
• Use the lug wrench or 21mm socket and a breaker bar to remove the front wheel lug nuts and take off both front wheels.
• Give the truck a shake to confirm it is stable.

Step 2: Identify Front Suspension Components

• Look at one front wheel well: you’ll see the coilover (shock with spring) going from the lower control arm up to the frame.
• On top, inside the engine bay, find 3 small nuts holding the top of the coilover to the body.
• At the bottom, find the large bolt passing through the lower control arm and the lower end of the shock.
• If your Tacoma has a front sway bar link near the shock, locate its upper or lower nut (you may loosen it for extra movement).

Step 3: Loosen Front Lower Shock Hardware

• Use a wire brush to clean rust/dirt off the lower shock bolt and nut.
• Spray again with penetrating oil spray and let it soak for a minute.
• Use a 19mm or 21mm socket and breaker bar on the lower shock nut, and a 19mm or 21mm wrench on the bolt head if needed to hold it.
• Crack the nut loose but do not fully remove the bolt yet. This makes final removal easier.

Step 4: Loosen Front Upper Coilover Nuts (Engine Bay)

• Open the hood. At the top of the shock tower, locate the 3 small nuts (not the big center nut).
• Use a 14mm socket and ratchet to loosen each of the 3 nuts until they are almost off, but leave a few threads engaged so the coilover doesn’t drop.
• Do NOT loosen the large center nut on the top mount.

Step 5: Free Up Suspension Movement (If Needed)

• If access is tight, you may need to disconnect the front sway bar link on that side.
• Use a 17mm or 19mm socket and wrench on the sway bar link nut; sometimes you must hold the center stud with a hex key.
• Remove the nut and swing the link out of the way.

Step 6: Remove the Front Coilover Assembly

• Place the floor jack lightly under the lower control arm to support it (do not lift the truck).
• Now fully remove the lower shock nut and slide out the bolt using the 19mm or 21mm socket and wrench.
• Go back to the engine bay and remove the 3 upper nuts completely using the 14mm socket.
• From the wheel well, pull the coilover out. You may need to push down on the lower control arm with a pry bar to create room.
• Note the orientation of the top mount and lower eye for reinstallation.

Step 7: Install the New Front Coilover Assembly

• Position the new complete coilover in the wheel well in the same orientation as the old one.
• From underneath, guide the top studs through the holes in the body. Thread the 3 top nuts by hand a few turns.
• Use the floor jack under the lower control arm to gently raise it until the lower shock eye lines up with the mounting hole.
• Slide the lower bolt through by hand. If needed, gently wiggle the coilover or use a pry bar to align it.
• Install the lower nut finger-tight using the 19mm or 21mm socket.

Step 8: Torque Front Coilover Fasteners

• In the engine bay, use a 14mm socket and 3/8" torque wrench to tighten the 3 upper nuts to 47 Nm (35 ft-lbs).
• At the bottom, use a 19mm or 21mm socket, wrench, and 1/2" torque wrench to tighten the lower shock bolt to 100 Nm (74 ft-lbs).
• If you removed the sway bar link, reinstall using a 17mm or 19mm socket and torque the nut to 74 Nm (55 ft-lbs).
• Repeat Steps 3–8 on the other front side.

Step 9: Reinstall Front Wheels

• Put the front wheels back on and hand-thread all lug nuts.
• Use the 21mm socket and ratchet to snug the lug nuts in a star pattern.
• Use the floor jack to lift the front slightly, remove the jack stands, and lower the truck to the ground.
• Use the 1/2" torque wrench and 21mm socket to torque lug nuts to 113 Nm (83 ft-lbs) in a star pattern.

Step 10: Lift and Support the Rear of the Truck

• Chock the front wheels securely.
• Loosen the rear lug nuts 1/2 turn with the 21mm socket while the truck is still on the ground.
• Place the floor jack under the rear axle (center) and raise until both rear wheels are off the ground.
• Place jack stands under the frame rails in front of the rear wheels on both sides and lower the truck onto them.
• Remove the rear wheels using the 21mm socket and breaker bar or ratchet.

Step 11: Remove Old Rear Shock (One Side at a Time)

• Each rear shock is bolted to the frame at the top and to the axle at the bottom.
• Support the axle near the shock you’re working on with the floor jack so it doesn’t drop or twist.
• Use a 17mm or 19mm socket and wrench to loosen the lower shock bolt and nut. Remove the bolt and set it aside.
• For the top mount, use a 17mm or 19mm socket or wrench to remove the upper bolt or nut, depending on design.
• Pull the old shock out. You may need a pry bar if it’s stuck.

Step 12: Install New Rear Shock

• Lightly coat the new shock’s bolt sleeves with anti-seize compound to help future removal.
• Position the new shock in place, starting at the top.
• Install the top bolt or nut by hand using the 17mm or 19mm socket but do not fully tighten yet.
• Use the floor jack to raise or lower the axle slightly so the bottom shock eye lines up with the mounting hole.
• Install the lower bolt and nut by hand using the 17mm or 19mm socket and wrench.

Step 13: Torque Rear Shock Fasteners

• Use the 1/2" torque wrench and correct size socket to tighten the upper rear shock bolt/nut to 21 Nm (15 ft-lbs) if it’s a stud-type mount, or to the spec in your shock instructions if it uses a through-bolt.
• Tighten the lower rear shock bolt to 72 Nm (53 ft-lbs) with the 17mm or 19mm socket and wrench.
• Repeat Steps 11–13 for the shock on the other rear side.

Step 14: Reinstall Rear Wheels and Lower the Truck

• Reinstall the rear wheels and hand-thread the lug nuts.
• Use the 21mm socket and ratchet to snug the lug nuts in a star pattern.
• Raise the rear slightly with the floor jack, remove the jack stands, and lower the truck to the ground.
• Use the 1/2" torque wrench and 21mm socket to torque the rear lug nuts to 113 Nm (83 ft-lbs) in a star pattern.

✅ After Repair

• Start the engine and gently bounce each corner of the truck by hand to help the suspension settle.
• Take a slow test drive around your neighborhood: listen for clunks, rattles, or pulling to one side.
• Recheck all lug nuts with the torque wrench after your test drive.
• Within a few days, get a professional 4-wheel alignment; front shock replacement can change alignment angles.
• Inspect all shock mounting points after 100–200 km for any looseness or unusual wear.
