Here are the annotated pictures I took last night.

You just need to use a pick tool or long narrow tipped flat blade screwdriver (with a thin edge) to push off the clip, and then the head just slips off. You MUST have a piece of wood or someone else holding up the hood before you remove the strut. You wouldn't want a headache or broken hand/finger from the hood falling down on you

The new struts come with me clips and you should be able to just push-snap the heads onto the knuckle studs.

Easy peasy.

 

Our 2010 had the engine hood gas springs give out this winter at 73,650 miles. It was one of the few things that I did myself since our Lexus dealer quoted me $418 for two springs and install. I like my Lexus and my dealer, but that is ridiculous. I went to Advance Auto Parts and purchased two Stabilus brand gas springs for $65. I reviewed several of the posts under this topic and thanks to all for the info and photos. I chose to remove the side engine covers and the installation was very simple. I spent more time removing and installing covers than installing the gas springs. I'm glad I did since I could look over the whole engine area.

 

can someone post instructions for the rear trunk lift gate shocks?

 

Same difference. Undo clip, remove strut, install new one. New one, slide clip half way off the strut head, before installation, when reinstalled onto the ball, press it back on flush firm.
