Using a windshield removal tool requires cutting a 2‑3 foot wire, threading it through the urethane seal, attaching T‑handle grips, and sawing the wire along the perimeter with two people.
A cracked windshield doesn’t have to mean a $300 shop bill. The Harbor Freight Professional Windshield Removal Kit (Item #96339) turns a two‑person afternoon into a straightforward replacement. Learning how to use a windshield removal tool correctly just means following the manual’s sequence, choosing the right wire length, and watching for the common mistakes that stall first‑timers.
What’s In The Harbor Freight Professional Windshield Removal Kit
The Harbor Freight Item #96339 kit comes with a braided cutting wire, a hook tool for feeding the wire through the urethane seal, and two T‑handle pull grips — one for each person. The official manual (Harbor Freight’s PDF for Item #96339) lays out the complete procedure. You’ll also need a separate knife tool to cut the initial gap in the rubber seal, plus ANSI‑approved safety goggles and heavy‑duty work gloves.
Harbor Freight also sells a cheaper alternative: the Pittsburgh Automotive Windshield Glass Removal Tool (Item #60298) at about $10 with a coupon. Its blade is noticeably weaker and requires a heat gun to soften the urethane before cutting. For anything beyond light duty, the professional kit is the better choice.
Step‑By‑Step Windshield Removal Procedure
The wire‑saw method works on any urethane‑bonded windshield — the Mk3 Volkswagen Golf shown in field demos is a typical example. The procedure requires two people and follows this order:
- Prepare the vehicle. Park in a well‑lit spot, set the emergency brake, and turn off the engine. Put on safety goggles and heavy‑duty gloves.
- Remove trim and seal strip. Take off all trim pieces around the windshield’s perimeter and the rubber seal strip.
- Cut a gap in the rubber. Use the knife tool to separate the rubber edge so the hook tool can enter.
- Cut 2‑3 feet of wire. The manual says 2‑3 feet. Many experienced users prefer 1‑2 feet for better control on tight angles. Bend one end of the wire over the groove on the hook tool.
- Push the hook through from outside. Working outside the vehicle, push the hook tool between the windshield and the frame until the wire end is visible inside the cabin.
- Pull the wire through from inside. Grab the wire from inside, pull it through to about half its length, and remove the hook tool.
- Attach the T‑handle pull grips. Push up the attachment post on each pull grip to expose the slot, feed the wire end through, and push the post back to lock it. Repeat for the second grip on the other wire end.
- Saw along the perimeter. One person inside, one outside. Move the pull grips in a sawing motion to cut through the urethane adhesive all the way around the glass.
- Lift the windshield. Once fully separated, carefully lift the glass away and set it in a safe spot.
- Scrape the old adhesive. Remove remaining urethane from the pinch weld so the new windshield has a clean bonding surface.
You’ll notice the wire cuts the urethane cleanly when the sawing motion is steady and even. If you’re shopping for a kit, our tested list of the best auto glass removal kits compares the top options side by side.

| Blade strength | Strong, cuts standard urethane | Weak — requires heat gun |
| Recommended wire length | 2‑3 feet (manual); 1‑2 feet preferred by users | Not specified |
| Best for | Full windshield removal on any bonded vehicle | Light jobs with pre‑heated adhesive |
| Price | Standard professional pricing | ~$10 with coupon |
| Number of people needed | Two | Two |
| Extra tools required | Knife tool, safety goggles, gloves | Same plus heat gun |

Common Mistakes To Watch For
First‑time users run into the same handful of problems. Knowing them in advance saves time and frustration.
| Mistake | Why It Hurts | How To Avoid It |
|---|---|---|
| Using a wire longer than 2 feet | Makes tight corner angles impossible to control | Cut 1‑2 feet for most vehicles; only go longer on large windshields |
| Not leaving enough wire exposed after pushing through | Leaves nothing to grab with pliers inside the cabin | Leave at least 1/4 inch of wire showing past the hook tool |
| Pushing the hook too hard on corners | Dings paint or damages interior trim under the rubber | Work gently on the corner relief cuts — feel the gap, don’t force it |
| Using the Pittsburgh kit without a heat gun | The thin blade can’t cut cold urethane and may snap | Pre‑heat the adhesive with a heat gun for 2‑3 minutes per section |
| Running the wire below the pinch weld on the bottom edge | Damages the vehicle body where the windshield bonds | Keep the wire above the pinch weld line when sawing the lower edge |
Safety Requirements And Setup
Windshield removal involves sharp wire, broken glass, and heavy lifting. The non‑negotiables are a second person — never attempt solo removal — and ANSI‑approved safety goggles. Heavy‑duty work gloves prevent the braided wire from cutting into your hands during the sawing step. A well‑lit workspace with the vehicle’s emergency brake set gives you stable footing while maneuvering the glass.
Cleanup And Preparation For New Glass
Once the old windshield is out, scrape every trace of urethane from the metal pinch weld. The new glass needs a bare, clean bonding surface for the adhesive to grip. Use a razor scraper or a wire brush attachment on a drill, then wipe the frame with isopropyl alcohol. That step is what separates a seal that lasts from one that leaks six months later. Check the condition of the trim pieces you removed — cracked clips should be replaced before the new windshield goes in.
FAQs
Is it possible to remove a windshield by myself?
The weight and awkwardness of a windshield make solo removal risky. The Harbor Freight manual specifically requires two people — one inside pulling the wire, one outside. A solo attempt increases the chance of dropping the glass or breaking it mid‑removal.
Can I use any wire instead of a kit?
Standard steel wire lacks the braided structure and T‑handle grips that give you control. The kit’s wire is designed to cut through urethane without snapping, and the grips let both people apply even tension. Plain wire makes the job harder and less safe.
How long does a windshield removal take?
A two‑person team working through the sawing steps steadily can remove a typical passenger‑car windshield in 30 to 45 minutes. Setup and trim removal add another 15 minutes. The cleanup stage before installing new glass takes about 10 minutes.
What if the adhesive is too hard to cut through?
Hard, old urethane may need heat to soften it. A heat gun applied for 2‑3 minutes along the perimeter turns brittle adhesive into material the wire can saw through. The Pittsburgh kit (Item #60298) requires this step every time because its blade is too thin for cold urethane.
