On my infinite list of things to do, this one seemed fairly easy, but as always, it is not.

Kinja'd!!!

I’ve taken apart my 505 V6 parts car a few weeks ago, scoring: A spare engine, a spare transmission, a radiator and front bumper for my dad’s 505 , a complete A/C system I want to convert to R134a and retrofit to my turbo diesel 505, rear electric windows that will also go into the diesel, headlights, grille, and some other little goodies.
Anyway, one of the main reasons I bought the car was the front suspension.

The V6 I bought last year (and haven’t ever driven) the front left suspension collapsed, and was repaired in a really sketchy fashion (I’ll post pictures when replacing it). My first thought was to replace the complete front suspension with GTD elements.

The issue is that on the GTD, The wheel hub and suspension strut are one piece, where the V6 has an offset wheel hub, allowing for larger wheels and the ABS system.

The struts from the parts car looked OK at first glance, but need some work

Kinja'd!!!

The bots keeping the hubs on the struts looked terrible, and I was mentally prepared to take the angle grinder to them.
In the end, they came out without any resistance, I was happily surprised.
Same thing for the brake calipers. Dismantling the struts was actually way quicker than I thought.

Kinja'd!!!

Cleaning the parts was more work than I thought though. I took a wire brush, angle grinder, and needlegun to clean them.

With the surface rust gone, it looked promising, until I noticed that one of the hub mounts was a bit blown up. Cleaning it revealed a small crack. I took a screwdriver to the hole between the hub mount and the shaft, and noticed it was all clogged up with rust flakes and dust.
I unclogged the holes and took the needle gun to the hub mounts to check their integrity. Bad news.

Kinja'd!!!

One side caved in badly, two caved in slightly, while one didn’t move at all. Surprisingly, the best and the worst were on one strut.

Anyway, since those are not available anywhere (I wouldn’t have tried to salvage these if they were), I’ll have to make this work.
Since my dad has better welding skills than I do (he DOES know what he’s doing) I’ll let him handle the reinforcement of the hub mounts.

Kinja'd!!!

If anyone has a better suggestion than “welding a thick patch over it” I’m open.

[edit] took some measurements (forgot a lot), in case someone is bored and knows something remotely close.

Kinja'd!!!

Of course it would help if I knew the overall length when mounted

I have never owned a car that has not had available parts, what a pain. Are there aftermarket coilovers or something that could be easily retrofitted? I only ask because if the mounting bracket looks that bad, I would imagine the strut itself is blown? Seems like a lot of work to put a (potentially) bad part back on the car.

Is there a workaround? Struts made to fit a different car that will fit the 505? I have Ford Pinto shocks on my lowered truck, for instance. All that was needed to make them fit was a bit of grinding. Does the 505 share it’s platform with any other cars? Find a car with a similar suspension of similar weight and you may be surprised. I am sure this is stuff you have thought of before, I am just thinking out loud. Good luck.

Kinja'd!!!

Do demonstrate, I cut these struts in half and put them back together with FlexSeal...

I don’t need no fancy rubber paint, bondo and sharpie will do

It shares it’s platform with the Talbot Tagora. I’ve never even seen one.
I think the “easiest” way would be to go regular 505 components, but that would probably mean a complete front suspension swap, losing the ABS, and probably having to put other wheels on it.
There is probably another car with similar struts somewhere, but finding info on dimensions is tough.
I was thinking about finding coilovers of similar length, but I’d have to figure out how to reproduce durable brackets to hold the hub.
It’s easier to get parts for my 60 year old Chevy, which is nice, but frustrating

I like French cars just like the next guy (I don’t own 4 for nothing), but things like these are a bit frustrating. Many other brands do make it easier for those driving cars clearly beyond the expected lifespan.

Having said that, my damn Mitsubishi Galant base model from 1996 (the model that ran to 2004) was a chore to get parts for already. And prices for some parts were insane. Exhaust segments for example, costing 3x what a similar part would cost for my similar era/size/price/engine Peugeot 406.

I lucked out with the Pajero, I guess I have to thank Hyundai for that.

Just for shits and giggles, what is the overall length and the diameter of the strut? Distance from the bottom of the strut to the bottom of the mounting bracket? Distance between the mounting holes? I am busy as hell at work, but this is infinitely more interesting to me...

Sadly, I don’t have the dimensions with me, but I can measure it when I come home

If you want help from some random guy on the internet, I would be happy to. I like this kind of search.

If there’s an new thing to be said about old cars it that every project will be harder than you thought.

I would pull the cartridges out and inspect them from the inside before trying to weld on them. The heat from the welder might damage the cartridge, so removing them is a good idea anyway.

This should start at the point where he’s removing the cartridge. If not, fast forward to 6:11.

The issue here is that those don’t have cartridges. The strut body is the cartridge

“I just have to replace this one part”... takes a few parts off. To get to the bad part... “oh and that looks broken too.”

It took me a month to do a timing belt replacement because I found out a the spot where the hydraulic meets the tensioner arm was warm out, And it took me a week to find the arm, and a over week for it to get here... and sevreal days for me to figure out where all those parts I took off 3 ago belong.

Are you sure? Did you try unscrewing the cap?

I watched a friend of mine’s uncle disassemble some factory struts which I thought were solid and un-serviceable. He pointed out a thin line that went around the top of the strut. To my surprise, he cut through it with a grinder and then unscrewed the top of the strut. The cartridge hidden inside slid right out.

Pretty sure. There’s this one guy who modified a lot of stuff on his V6 and he had this page where he showed how he had done it, but he never updated

I’d still start by removing the cap just to see what’s going on inside before I welded anything. Good luck with it!

Don’t know if this will help or not, but here’s a Monroe catalog by dimension. Starts off with shocks, but transitions to struts a few pages in. I’ve put it to good use on a handful of custom projects.

And here’s Gabriel’s. There’s two links, one for their “Mount codes”, and one for their actual struts. Once you get a part number, you should be able to cross reference something available in store or online.
