Front bucket seats

• 1). Use a socket wrench to remove the bolts which fix the front bucket seat on to the floor of your GMC vehicle. Lift the seat out of the vehicle.
  
  
• 2). Move the seat to a clear work area. Turn the seat upside down. Locate the bolts on the bottom of the seat that secure the upholstery covers on to the seat. Remove the bolts using a socket wrench. Keep the bolts in a safe area for reattachment later.
  
  
• 3). Slide the upholstery covers up the seat all the way to the top. Lift the cover off the top of the seat to remove it completely. Discard the damaged cover.
  
  
• 4). Place the opening of the new upholstery cover over the top of the seat. Pull the cover down the seat so that it covers the entire seat. Reattach the bolts to the underside of the seat with a socket wrench to secure the new seat upholstery in place.
  
  
• 5). Lift the seat back into your GMC vehicle. Secure the mounting bolts between the seat and the floor of the vehicle in order to secure it back in place. Repeat the process on the second front seat.
