Saris Bones 3-Bike Rack Installation - YouTube

I drive a '02 Blazer, 2D with no hitch. I want a bike rack that will fit and I was wondering if one like in this youtube video would work for me?

Also, as a completely unrelated issue, do you have any suggestion why the hydraulics on the back window no longer work? I have to hold the gate open while unloading things so it doesn't eventually drop on top of whoever is underneath it.

Thanks

 

The hydraulics issue the gas pistons are wore out and you can get replacements at any auto part store

 

the "hydraulics" on your back gate are called struts. They get wore out. Like was said, they can be found any any parts store
