Are you referring to the gas cylinders which hold the trunk lid open? I'll have to change mine also but haven't looked into that yet.

Try searching for trunk shocks. I know that "gas pressurized spring" is BMW's official name for it, but no one calls it that. It should be a simple matter though, just unbolt it, and make sure to support your trunk in the process! I'm assuming you already have the part?

Some people call them trunk struts. I replaced mine couple weeks ago. Very easy to do.
1. Support your trunk in open state and do one side at a time (it is very heavy).
2. Remove retaining semi-ring on top - just push on its ends with flat screwdriver on the opening side. Just make sure you will catch it when it will pop out.
3. On the ball joint side of the strut - you have to use thin flat screwdriver and stick it under that metal flat spring clip and either pull it out or slide it to the side. Basically you have to move it enough so that it will not hold to the ball. Once you will try it you will understand what you need to do.
4. Remove your strut by sliding top portion to the side and wiggling bottom ball joint away from the ball.
5. Installation is in reverse.

As mentioned there is a circlip that holds the strut to the ball. Pry off the circlip and the strut will pop right off. Don't let the trunk hit you in the face the first time you open it with new struts.

Both of you misunderstood me...

I'm asking if the little ball strut comes off the entire pump I'm trying to add some die springs to it but cannot get over the "ball strut"

All I did was point folks to the DIY that cn90 wrote.
If the answer isn't already in that DIY, I'd be surprised because cn90 does good DIY writeups.

Are you saying cn90 didn't cover this topic in his DIY I pointed everyone to?

No, he wants to rig it with a supplemental spring so he doesn't have to buy new struts.

Stabilus is the BMW OE manufacturer, you can get a set for $50.

What's a "die spring?"

Can't imagine why you'd want to kludge it when the struts are so easy to replace.

Good information for this thread:

Ah, like the JB Weld threads, I missed the point entirely!
Mea culpa.

As I explained in a VANOS solenoid check valve thread today, since almost all questions have detailed answers already and it's just that the OPs don't look for them, my MO, as of late, has been:
> E39 (1997 - 2003) > M62TU vanos solinoid check valve

A question was asked, and all I did was look up the question.
Since I found that answer in the same spot anyone would look, I had wondered if the procedure was missing a step or three (it happens).

Nothing clever whatsoever.

Let me tell you my M.O. for most threads:
a) I skim them (if it takes me more than about five seconds to skim the entire thread, that's too long).
b) I decide what the basic question is talking about
c) I type the keywords and provide the link
d) I move on to the next thread.

Since I skim threads, I can easily get the specific question wrong; but, I generally have the general topic figured out in those few seconds.

In most cases (99% of the time lately), the answer to the question has been well documented (as it appears to have been in this case), so, my MO should work if the person clicks on the links.

In this specific case, I had known (from the way the OP was written) that the OP had already said they had clicked on the links, so, I clicked on them myself, to see why they hadn't answered their question.

When I saw the answer as plain as day, I questioned my assessment of the problem set (which sometimes I get wrong).
In that case above, the OP simply didn't read the (very detailed) Besian DIY before asking the question; however, in the case of the thread here on the shock ends, the OP knows about the DIY and the OP is asking a specific question that is apparently not covered in the DIY.

For that, I'm no good, and I pass.

Kudos to the OP for asking how, and thanks to you for explaining that I missed the point, but, I can't help here, since I've never done the job.

I can only reference the OP to those who did (and I've done that).

Thanks bluebee u know I appreciate any and all the info u give here, you're like the wiki for bummerfest lol no lie...

But yes this mod isn't covered in none of the DIYs here of course before making this thread I searched and didn't find anything.

I also am replacing my old struts with new OEM struts and is on its way... Thanks to the given reference in this thread hopefully these new struts the ball joints can unscrew so I can begin my mod.

Thanks again
