🔧 Savana - Front & Rear “Strut” (Shock Absorber) Replacement
Your Savana does not use struts. It uses shock absorbers (front and rear) with torsion-bar front suspension and rear leaf springs.
This job replaces the shocks to restore ride control, reduce bouncing, and improve braking stability.
Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours
Assumption: Stock suspension height and hardware.
⚠️ Safety & Precautions
- ⚠️ Support the van with jack stands; never rely on a floor jack.
- ⚠️ Let the exhaust and suspension cool before working near them.
- ⚠️ Wear safety glasses; rust flakes fall when bolts break loose.
- ⚠️ Do not loosen or adjust torsion bar adjusters; they are spring preload devices.
- ⚠️ If a bolt fights you, stop and use penetrating oil; snapped shock bolts are a major delay.

You'll need the following tools for this repair:
- Floor jack (rated 3-ton minimum)

📋 Before You Begin
- Park on level ground, shift to P, and set the parking brake.
- Place wheel chocks at the tires staying on the ground.
- Soak all shock mounting nuts/bolts with penetrating oil for 10–15 minutes.
- Use a paint marker to mark which shock came from which corner if you’re comparing parts.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Lift and support the front
- Chock the rear wheels using wheel chocks.
- Lift the front at a solid crossmember using a floor jack (rated 3-ton minimum).
- Set the frame onto jack stands (rated 3-ton minimum).
- Remove both front wheels using the correct socket set metric 10mm-24mm or socket set SAE 3/8"-7/8".
Step 2: Remove the front shock (one side at a time)
- Locate the shock: it’s the cylinder between the lower control arm and the upper mount.
- Clean exposed threads with a wire brush.
- Hold the shock shaft/upper hardware as needed with a wrench set metric 10mm-24mm or wrench set SAE 3/8"-7/8", and remove the upper nut using a ratchet 3/8" drive and socket set metric 10mm-24mm or socket set SAE 3/8"-7/8".
- Remove the lower shock bolt/nut using a breaker bar 1/2" and appropriate socket set plus a matching wrench set to hold the opposite side.
- Pull the shock out; use an 18" pry bar if it’s stuck in the mount.
- Bounce control test: bad shocks leak oil.
Step 3: Install the new front shock
- Compare old vs new length and mounts before installing.
- Position the new shock into the mounts by hand.
- Start the lower bolt by hand using your socket set and wrench set.
- Install the upper bushings/washer/nut (if equipped) and snug using a ratchet 3/8" drive and socket set.
- Tighten fasteners with a torque wrench 1/2" drive: Torque to factory specification.
- Apply threadlocker medium strength only if your replacement hardware instructions call for it.
- Tip: Tighten rubber bushings to spec, not crushed.
Step 4: Reinstall front wheels and lower
- Reinstall wheels using the correct socket set.
- Lower the van from jack stands using the floor jack.
- Tighten lug nuts with a torque wrench 1/2" drive: Torque to the door-jamb tire/lug specification.
Step 5: Lift and support the rear
- Chock the front wheels using wheel chocks.
- Lift the rear under the axle housing using a floor jack (rated 3-ton minimum).
- Place jack stands (rated 3-ton minimum) under the frame rails, then lightly support the axle with the jack.
Step 6: Remove the rear shock (one side at a time)
- Rear shocks mount between the axle bracket (lower) and the frame bracket (upper).
- Brush and oil the fasteners using a wire brush and penetrating oil.
- Remove the lower bolt/nut using a breaker bar 1/2", correct socket set, and a matching wrench set.
- Remove the upper bolt/nut using a ratchet 3/8" drive, extensions 3/8" drive (3", 6"), and correct socket set.
- Remove the shock; use an 18" pry bar if needed.
Step 7: Install the new rear shock
- Install the upper mount first by hand-starting the bolt using a ratchet 3/8" drive and extensions 3/8" drive (3", 6").
- Install the lower bolt next; you may need to raise/lower the axle slightly using the floor jack to align holes.
- Tighten fasteners with a torque wrench 1/2" drive: Torque to factory specification.
- Tip: Align holes with the jack, not a hammer.
Step 8: Lower the rear
- Remove tools from under the van.
- Lower the axle slightly, remove jack stands, then lower fully using the floor jack.
✅ After Repair
- Road test at low speed first; listen for clunks over small bumps.
- Recheck that all shock bolts are tight using a torque wrench 1/2" drive: Verify factory specification.
- Inspect for any contact with brake hoses/ABS wiring near the shock mounts.
- Replacing shocks does not usually require an alignment, but get one if you notice pulling or uneven tire wear.
