The other day I was up North where it is colder and noticed the struts were not doing a good job of holding up the rear hatch.
Easy solution, ordered new struts off Amazon.
This is where the mistake happened. Didn't occur to me how heavy our back hatch is. Popped off the left side strut and the hatch cam crashing down shattering the rear glass.
Dumb mistake. Should have used a prop rod.
Next week I get new glass installed for $380.
Expensive mistake, but I am an old man and make stupid mistakes.
