Nothing to do with the top bearings, the piston should never be able to come un-screwed from the rod, unless it was put together improperly... I had this problem once with Bilstein inserts that had just been re-built, when I was installing them into my strut tubes they flew apart. Bilstien said that the rods were supposed to be "peened" to stop teh piston un-screwing, but weren't.

I think that was Ryan. It was gone by the time we got there. The right rear suspension failure is a result of previous owners modifying the knuckle to accommodate a bigger shock to stop shocks from breaking. I have to try and see if I can get the replacement knuckle reinforced to stop it from breaking again. Or something crazy like getting a knuckle machined up. For GCFR, it's no problem, I can run it with the same machining. For the front left failure, I have no clue why it failed other than I'm too rough.

Alexei, I've been fighting with trying to make something acceptable for the rear of a Suzuki and its been hell with that dumb socket in set up...
Its just like Xratty and Golf IV front

I tried ordering some shocks which after long delay,came and they were normal 50mm and I agree boring the whole to 50mm is bad from 2 points of view A) the material (cast steel? Iron?) around the outside is THIN and obviously weak... and cool smiley if its weak it MAY fail and if it may fail then the replacements need to be modded.


I've come to the conclusion the best thing is the simplest: just use the machined bottom to my ordinary struts which are made for Xratties.
and extend the towers up maybe 125mm to accomodate the "strut" and get good travel..
Ie mod the bodyshell once and be done with it.

Whaddya think?

I won't have time before GCFR, but I may be willing to do some things like that and see if I can get it reliable. The one problem in my noob mind is the roll cage ties into the rear mounts as well, and I'm not experienced in saying "oh yeah, that can be modified easy" vs. having to modify the cage and do a shitload of work. Let me get GCFR out of the way and then I'll post pics and such and see. I'm going to try and get two more sets of rear knuckles from another guy parting out a car in addition to a pair I'm pulling from a car I have now. I won't modify one of the sets.

You're right about the socket collar thing, it sucks. So. much.

Hey Alexei, I have piles of photos of the knuckles rear and I can post them up and we can do some sketches and get this figured out..I know what needs to be done to make it rally worthy from a "clean sheet of paper" viewpoint, maybe you take some photos of the inside rear of the car to see if a reasonably easy way can be done to dodge the cage and minimise the fawking round.

Let's open a new thread in Construction but take some piccies of your set up..

What I have in mind is basically a strut with at least 190mm travel, stock is 160mm but I'm thinking if we have to cut the inner fender well and zap in something like this:


Then we can simply choose to make it this high or that high...

And more travel in back isn't limited by CV joint angulation so in a way, why not do more travel?

So our story.

We suffered a strut failure (not johns). We were trying something new and apparently it wasn't up to snuff.

About .5km before we actually ended up off (and rolled), something felt odd, very much like a flat. Car was pulling and seemed to "drop" in the front corner. We came down into that "water" splash and an already reduced speed, and the entire corner of the car decided it wanted out. It separated the ball joint, and pulled us off the road. We were along for the ride. We got pulled off into the bushes, and spun 90 degrees to the road. As we were almost stopped, something caught the passangers side, and tipped us onto our side! Apparently i should have known better than to suspect a flat DMACK winking smiley

No glass was broken, just a couple fenders and a hood from resting against some really small trees.

Zzzzzz-Zzzzzz

Wait till you see the last stage. We were going a bit slower to try to save the diff, so my note-calling was somewhat less enthusiastic. It even puts me to sleep watching it now.

The last video should be posted up tonight.

I meant it as a compliment, to be fair.

Akin to Autonomous Sensory Meridian Response.... Just so soothing.
