Aimee handed me new rear window lift struts a couple days ago so i put those on. she tells me the hood ones are ordered as well.

 

does everyone have to replace these things every couple years, or does the AZ heat wear them out faster?

I've owned my jeep 5 years & had to replace the rear hatch struts only once a long time ago, replacements are still working well.

I did my hood struts a couple years ago, they need to be replaced again. They work in the morning when the fluid is cool but as soon as it gets warm they are a no go.

How Odd… :confused::confused:

 

That's just backwards of the way they normally fail to provide sufficient holding pressure to maintain the hood or lift gate opened position.

 

The reason is that they are "Gas Springs". IE: the mechanism by which they apply pressure to hold the gate/hood open, is via gas pressure acting as the spring. In every instance I'm aware of they have higher pressures when warm, thus work better warm, than cold.

 

The "killer" of these things in our AZ environment, is the highly abrasive dust, which damage the seals and the gas charged bags, which then in turn allows the gas to slowly deplete/escape, causing them to become less effective.

I'm not sure why, the ones that get used more often seem to last longer, at least for me. In the morning the hood will stay up, in the evening it won't stay up at all.

My rear liftgate struts seem to last a couple of years and then they become the hood struts which last a long time. Circle of life I guess.

interesting, on the WJ my hood ones go out first, then the liftgate, then the rear glass ones never seem to die but i never use it and it's light too.
