I'm trying to remove the nut that hold the shock in place. I need to replace the strut.

I've tried heat, but maybe it wasn't hot enough. How hot do I get it?

I'm using an 18" pipe wrench. It's the same one I put it on with. I changed the shocks about a year ago. It will not budge. It's hard to put leverage on when it's in the vise. I even hit the wrench with a dead blow hammer. It's currently soaking in penetrating oil.

I tried using a drift and hammer to break it loose. Didn't budge.

The next step would be to use a cheater bar on the wrench. However, I'm afraid I won't be able to hold it in the vice securely enough.

Does anyone have any other ideas?

Thanks!

Can’t beat the proper tool for which it was designed.

Pipe wrench is working against you. As you try to loosen, the wrench is deforming and compressing the retaining ring deeper into the threads creating a bind.

This type of spanner will also work well - get right size for strut diameter and you may have to grind the hook to fit.

Be careful with the heat. Bilstein struts are gas charged monotubes and the heat will damage the internal seals of the floating gas piston. At its worst strut can explode if gas is heated too much.

The nut diameter is 54mm. What does the 36mm in this link refer to? Or is this just an example?

I can't confirm that it fits my 914.

This reminds me why I used a pipe wrench. I could find the tool, but I could not confirm it was the right size or that it would fit the nut on my car.

I may go the spanner wrench route, since those are more versatile.

Measure the Bilstein sliding strut tube - my bet is that it is about 36mm or slightly smaller so that the tool can pass over the strut and engage the two slots.

It's 40mm. I would really like to know what the 36mm dimension in the tool description is referring to.

Dang! Good thing I wasn’t betting real money on that. (IMG:style_emoticons/default/lol-2.gif) Could verify proper tool with Bilstein. They usually have good tech support.

I have an email in to Bilstein. I'll let you all know what I find out.

I found what appears to be the right part here:
https://www.mk1autohaus.com/Bilstein-Strut-...7mm_p_8039.html

But when I went to my cart, it took me to a page that redirected me to an Ebay store that is no longer active. No credit card info was entered, but I thought it was odd.

I think the dimension refers to the inside distance between the two tabs.

Prices are all over the place and most sites have no info about the dimensions.

I'd prefer to use the right tool, especially since it works with a 1/2" socket. My breaker bar is 24" long and it will provide me with lots of leverage.

However, I might have to just get a hooked spanner and use that with a piece of pipe.

I think you’re on the right track - has to vary based on strut diameter and diameter of the nut.

Just be aware that the hooked spanners can slip off the hook especially when a pipe gets involved and you really start reefin’. They like a perfectly straight pull. Ask me how I know. (IMG:style_emoticons/default/sad.gif)

14" pipe wrench has worked just fine for me, maybe a bit of Mapp if necessary

(IMG:style_emoticons/default/dry.gif) - would be funny if not so sad that suppliers can’t be bothered to actually state what diameter strut tube the Bilstein tool is for or to at least confirm it is for 914/911 sized struts. Pricing is all over the map too. Sierra Madre sells them which you would assume would be for 911/914 but they also have a little foot note that you may have to modify the tool - Really?

Who wants to pay $50 for a simple stamped tool only to find out it doesn’t fit and needs to be modified when it appears the next guy is selling the same tool for $15.

I also see Summit sells a Bilstein branded 60mm spanner wrench but that appears to be for adjusting coil over spring perches. Would probably work.

I suspect Bistein will come to his aid with a proper tool number.

Best I’ve found - I think tool number is MS 08/6

There are basically two version floating out there when you attempt a google search: E4-MS 08/4 and 08/6. the first link thin this thread, EDO Performance, wouldn't even allow me to order the item... said it can't ship to my Maryland address. I thought $5 was worth ordering in the blind just to confirm

I just assumed i would be welding together tools for the ball joint and strut, but I briefly had hope there was a confirmed strut option when I saw this thread... either way, I have enough 3/16" plate to make it myself lol out of spite for places that charge +$20 for stamped metal.

(IMG:style_emoticons/default/happy11.gif) You’ll have burned $20 in time / labor by the time you cut the fist piece of steel. But, I know the feeling. Not a hard tool to make at all if you can weld.

You definitely won’t like the price of the ball joint tools. I bought the Baum. It will out live me and makes me smile when using it. There is a guy on TheSamba that makes a homebrew machined version for about $45 that @mepstein loves and recommends.

He’s also on pelican & early911sreg . JimmyT. One piece hardened & chromed tool steel. Snap-on quality for craftsmen prices. He’s a machinist and makes a bunch of amazing 911 parts. Also a pleasure to buy from.

I'm listening. That ball joint tool was the main thing steering me to DIY, but $45 vs $120 is enough to make me change my mind about using Argon for that project.

@mepstein do you know if he has a listing anywhere? or do I just need to find him and send a PM?
