DIY endlinks using Heim joints
« on: November 10, 2016, 08:23:40 am »
Once again I'm chasing clunks in the front end. My thoughts are:
1. sway bar bushings (again)
2. end links
3 blown Koni's which look sweaty but that could well be the Spray Fluid Film sticking around.

I'll start with #2.
So my front end links look like this:


They'd be easily replaced by those cheap Whiteline's I bought off... oh uckfay, I sold them. So I started looking around for new or used replacements and all the ones I enquired about were either too expensive (new) or sold.

Then I started looking at DIY options and found this on NABISCO:
DIY Front Endlinks (with part #'s)
Potato:

This assembly image popped up in another thread (note awful angle):


And finally, I struck gold in this thread where the fellow made his own cone spacers:


I started a brief search for the parts online and found ludicrously expensive ones locally in places like Acklands Grainger and then there's eBay (example fitting)

Anyway, my question for WSC is has anyone tried this (successfully) locally within, say, a $50 budget?

In my experience, those types of joints are quite expensive. Additionally, there are a couple of problems with using them on a daily driver:
1) They are unforgiving. If they're super tight, they might be relatively quiet themselves, but the sway bar bushings will see additional loading and will wear out faster and you will likely see an overall increase in noise.
2) They won't last long due to grit and corrosion.

I've considered making my own urethane bushings for my GNP end links and having custom ball/spacer pieces made at our facility in China to allow higher degree of freedom and hopefully reduce the frequency of hardware loosening off and becoming noisy, but I haven't taken the time to work on that.

Likely your best bet if noise is your primary concern and you're on a budget, is to go to NAPA or something and see what their OE replacement parts look like.

Yea, when an OE replacement endlink is $15, why dick around?

Because he has an upgraded sway bar that could likely snap an OE endlink? As you can see, he's replacing aftermarket links already (looks like whiteline/Group A/kartboy).
If the sea was vodka, and I was a duck.
I would swim to the bottom, and drink my way up.
But the sea isn't vodka, and I'm not a duck.
So give me the vodka, and stfu.

Actually, I have a stock FSB so if OEM's are $15 I'll grab them.

No way man, look at the peeling rubber all around. They're OEM as.

And, fwiw, I have stock endlinks with bigger sways. Haven't snapped yet.

I mean OE equivalent, on RockAuto.

Actual Subaru ones are probably a small fortune.

If memory serves, the S2000 guys were looking into this.

I think Murray definitely was, and Grant was kind of interested but not enough to make it happen.

Since McMaster Carr insists all Canadians are terrorists I couldn't find a place to DIY some endlinks together.

uh...  they clunk.

After a couple years any unshielded sphericals used like that are going to clunk.

way back when I ordered my swaybars, springs from Dales, he gave me a set of whiteline spherical end links for free. I sold them hah. I'm guessing they aren't a big seller..

So my front end links look like this:




Anyway, my question for WSC is has anyone tried this (successfully) locally within, say, a $50 budget?

I'm brand new to Subarus, and I gotta say... the endlink design on a lot of the models leaves a lot to be desired. I've seen so many pictures posted online of the terrible geometry of the front endlinks mounted between the end of the sway bar and the control arms. (The rear endlinks are nothing to be proud of either.) I'm interested in replacing the plastic endlinks on my '98 STi wagon, but I'm still not sure of the best route to go.

Although the Whiteline endlinks (KLC182) pictured below definitely don't qualify for being within a "$50 budget", and they're not even designed for my car, I'm wondering if the end that mounts on the control arm (similar to picture above) could be narrowed and made to fit between the two "ears"? This is about the only style that looks skookum enough to withstand any abuse. Comments?

I'd also avoid whiteline for that sort of thing if you're intending on winter driving the car.

Why?

Whiteline stuff doesn't have good corrosion resistance in my experience or research.

Since you're in Vancouver, it might be okay.

Not every idea is a good idea though. :P
He probably meant that there is likely an equivalent WL part designed for that specific application. If you're already spending the $ why not just buy the one that already fits?

Hadn't switch found an audi endlink with the same dimensions that was aluminum? (and also cheap on RA)
Update: it was for the rears. and in typical sss fashion, he has purchased the part but it is in a different town.

Whiteline has pretty terrible coatings and theyre made for Australia weather so they like to rust out.

Yea, Modification ideas, you had an idea and I gave an opinion. You're trying to engineer something you can easily buy off rock auto thats purpose made for your application.

Okay, good point on the lack of corrosion resistance... but yeah, Vancouver winters are very mild. Not much salt used on the roads here. Ironically however, the last three or four weeks have been much more winter-like than usual for this area. Snow has been on the ground for the last two weeks. It's raising havoc with the local banana crop.  ;)

You think I haven't looked?  :-\ The reason why I'm interested in a "modification" (and probably why the OP started this thread) is that both the OEM and off the shelf aftermarket endlinks offered for this model Subaru are all lousy. That endlink you've supplied a link to performs very poorly unless the end of the sway bar and the control arm mount are perfectly lined up. The 'net is littered with pictures of this style of endlink failing.


Hadn't switch found an audi endlink with the same dimensions that was aluminum? (and also cheap on RA)
Update: it was for the rears...

Yes, I'm aware of that option. It's an aluminum front endlink for an Audi A4 that can be used on the back of some Subarus. I'll probably go that route for the back of my STi. The front is turning out to be a bit more of a challenge.


Yea, Modification ideas, you had an idea and I gave an opinion.

Perhaps posting something other than... "just get something designed for your car" would be a little more helpful and appreciated.


You're trying to engineer something you can easily buy off rock auto thats purpose made for your application.

"Easily"? Okay then, how about if you try and find something designed for this car that has the same features and mounts on each end as the unit I earlier pictured (with a ball link on one end). As far as I've been able to ascertain, there is nothing other than variations of the same crappy "dogbone" style endlink that isn't able to compensate for the poor geometry of the endlink mounts on these cars. (Yes, people have tried using Heim joints, but because of them being unsealed and open to the elements, lack of durability becomes a rather limiting factor.)

Here's an example where washers/spacers are used to try and help line things up with a "dogbone" endlink. It's pathetic!




Even though it's made for the purpose, it might not actually work.

That's exactly how I feel about the OEM and off the shelf aftermarket endlinks offered for this car!  ;D

Huh I'm surprised to hear this about WL.
I've got their end links in the front for 2.5 years now, and they still look brand new... Just got their rear links end of last year, we'll see how they hold up.

Pretty off topic.

Okay, but what are you hoping to accomplish by finding a 'superior' unicorn endlink?

What tangible difference do you think it will make?
