Preparation

• 1). Purchase a windshield that fits your Toyota Tacoma's specifications. Replacement windshields generally come with urethane adhesive and primer. If not, purchase them at an auto parts store.
  
  
• 2). Loosen the screws at the base of the rearview mirror mount with a screwdriver. Lift the mirror from its base and save the assembly and the screws in a safe place.
  
  
• 3). Find the base of the wiper arm and pull the plastic housing up and off. Under the housing you'll find a 13 mm bolt. Remove it with a wrench. Slide the wiper blade and arm off the bolt.
  
  
• 4). Remove any after-market products that may be obstacles. Many Tacoma owners soup up their trucks; some products such as roof racks and spotlights will be in your way.
  
  
• 5). Prop open the hood.
  
  

Removal

• 1). Remove the rubber lining on the outside of the car with a pry tool or the blade of a knife. Once you loosen it, the rubber will fall away easily.
  
  
• 2). Break the adhesive seal from the damaged windshield by running a thin knife blade between the car and the windshield.
  
  
• 3). Push the windshield up and off its mount from inside the truck. If the windshield has cracks, be careful not shatter the glass. Too much force will send the damaged glass forward once it releases from the old adhesive.
  
  
• 4). Clean the mounting area. Remove as much of the old gasket and adhesive as you can with a utility knife.
  
  
• 5). Make sure the new windshield is clean. Dirt lessens the effectiveness of adhesive.
  
  

Replacement

• 1). Brush a thin coat of urethane adhesive primer onto the windshield mount. This prepares the molecules of the mount to bind with the urethane.
  
  
• 2). Bead a line of urethane adhesive on the mount of the vehicle. Use an electric caulk gun to get a consistent bead.
  
  
• 3). Place the new windshield carefully. Try not to touch the adhesive. Your truck may have a mount on the lower end, near the hood, to aid you in the placement of the glass.
  
  
• 4). Allow the adhesive to set. Follow the recommendation of the adhesive manufacturer. Run two pieces of wide masking tape from the top of the windshield onto the roof of the vehicle, one over the driver's side and the other over the passenger's to hold the windshield while it sets.
