Just replaced rear door gas struts. To powerful! Slams door open. Is that normal?
 
99 XJ

I bought replacement struts from Oreily Auto Parts for $20 each. Seemed like a great price since half what OEM or Crown cost off Internet.

However, these Oreilly struts slam the door open so hard it bounces up and down 3 times. They are to powerful and NOT progrssive rate.

Are OEM or Crown springs progressive rate? i.e. - do they slow down near end of travel? Is there a brand that makes progressive rate struts for rear door?

Do OEM or Crown struts slam door open?

I can still return the Oreilly struts.

What struts should I buy?

I got mine from the Zone and they are perfect... Except now my hatch sticks a bit closed and can be a bugger to open.

I just bought some new ones from advanced yesterday and i was surprised at how stiff they were, and was wondering if they were too stiff. It says right on the package they are not designed to be compressed by hand.

So i guess its normal, its just a matter of whether you want your lift gate to hit you in the top of the head from falling or smack you in the face when opening.

They loosen over time, but you need OEM spec if you have an older XJ because the fiberglass hatches wont handle it.

I got my struts from a ford explorer in the JY and I love the way they operate! not too stiff or loose

That doesn't sound perfect to me. Sounds like the opposite problem.

Years ago I replaced struts on my 96 XJ and they worked perfectly from the first day installed. I wish I could remember the brand.

I thought old XJ hatch was steel and newer XJ hatches were fiberglass. Do I have that correct or backwards?

Does any brand make progressive rate struts for rear door?

That is backwards, old xjs have fiberglass hatch, newer ones are steel hatch. Like 98+? Are steel.

Motorcharge 04-15-2013 02:57 PM

97+ are steel. Couldn't see his year on mobile, but the OP is fine. Old fiberglass ones will start to break in that area if they struts are too strong.

X2
Ones I bought about 5 years ago started out forceful, then mellowed over time.
Now, if it's cold enough, they almost don't want to open on their own.

I also have bought the ones from O'Rileys and they are strong at first but will loose some of that pressure over time.

Had the same problem when I bought new ones from O'reily's, it was way too strong. So I changed 1 of them back to the old, weaker ones. So i have 1 old and 1 new one. Has been on for a few years, and works great still.

IMHO I would far rather have strong lift struts and it pop open than a weak system that will cause problems with the latch not disengaging and not letting it open. Many people also end up breaking the license plate light cover by shoving on it in an attempt to get the hatch open. But I will also say that most of the time when the rear latch does not disengage it is due to the latch arm needing adjustment.
