Fun with Struts

Having replaced our minivan’s struts, I thought it wouldn’t be much of a problem to help my brother-in-law replace his struts. Or rather, his minivan’s struts.

Even though I knew what to do and how to do it, it still took about 2 hours per side. The main culprit is the sway bar link bolt. If you have any vehicle whose sway bar link design includes using an allen wrench to hold the bolt still while you turn the nut with a normal wrench, replace it as soon as possible.

Looking back, I think it would have been worth it to get a 3/16″ hex head socket for my wrench, rather than trying to use an allen wrench. As it is, I lost another 3/16″ allen wrench. I have about 3 sets of allen wrenches, you know the plastic organizer with 8-12 allen wrenches lined up. And they are all missing only the 3/16″ size. I would love to be able to buy a 5-pack of 3/16″ allen wrenches. But all I can do is buy another full pack of all the sizes, because no one sells normal allen wrenches of just one size.

Technically speaking, I didn’t lose my last 3/16″ allen wrench. I have it, but I can’t use it anymore. Before starting the project, the allen wrench looked normal, with a ball-type thingy on the long end and a standard end on the short side.

Here’s what it looks like now:

Notice the ball-end has been snapped off. It’s stuck inside the sway bar link bolt. That was after the first problem:

I had to switch to the long end because the short end was too far gone. It ended up rounding itself off, but that’s after it twisted at least 100 degrees around. That bolt did not want to give up, and it was stronger than the allen wrench.

After running out of allen wrench, my only option was to grind the bolt off. That was slow going. I really need to get a cutoff wheel for my angle grinder, rather than just a grinding wheel. And it heated up the bolt so much the ball joint on the other end of the bolt fell apart. The ball joint of the sway bar link, not the wheel hub ball joint. That would have been bad.

After spending a while grinding off the bolt but getting only about 1/3 of the way through, I thought I’d try again because the grinding was taking forever. This time I clamped some vice grips onto the other end of the bolt (the stock link is perfectly round, so you can’t get a good grip on that end – except the grinding gave it a nice big flat spot). The nut certainly wasn’t freely spinning, but I could turn it. I think the intense heat is what broke it free. If I had realized that earlier, I could have saved myself some time.

After all that, I had a new sway bar link to put on but no allen wrench to keep the bolt from spinning. I was so glad to see the aftermarket part did away with that design and the bolt can be held in check by a hex shape on the ball-joint end. No allen wrenches needed.

It took us two days to do the job, because they gave my brother-in-law one strut that was correct and one that was backwards. At least he thought to compare the new strut to the old before we took the old one off. So the first day we replaced the one strut we had, and then he went and got the backwards strut replaced, and he came back the next weekend.

All’s well that ends well.

    That was an adventure. I have a replacement 3/16 allen wrench coming :-)

    You can get a set of two 3/16″ allen wrenches off eBay for $2 total (including shipping). No idea what the quality is like, but let me know if you want one.
