Front straight lower suspension arm failure - can it be prevented?

[Davezj]

the final one is kind of what i was thinking of,
i would have made the smaller top bit fold down over the edge of the hub carrier then fold back up to form the lip.
the bottom bit would form and arc with a lip on it to inter lock with the top bit.
i was thinking of securing the bottom bit to the suspension fork bolt. with a U shape channel running under the arm that would take the load in a failure. with some kind of loop over the top to stop it falling away when not in failure mode.

it is just the suspension travel up and down we have to think of so the lips do not catch on eachother at the extreme of movement.

Yep can see what you're thinking. Have got a couple more to put up, then I think have to look at trying one. Will post em later.

i have had a look at my suspension this morning and the wire rope option will be a quick and easy solution.

i measured the minimum length of wire rope will be 225mm but you will need the right sort of fixing for it. i have wire rope clamps but not sure this will be good enough.

Andy can you give me this info you were talking about, the 4mm wire rope with the high breaking strain and the best sort of clamp to secure it. the rope clamp i was going to try is this one.

i was going to thread the wire rope from either side and then loop the ends back through again, then clamp it tight.

Think it was Louis with the rope info. Have not really had a chance to do much more on this as I have been busy in any spare time that I have preping the car for Easter. Will get back to it though after the break.

i did the 3D model of the metal slide past bit but i can't show it to anyone as the file format is not correct for a simple viewer.

Just do a few print screens of good angles and post them.

good point. i will do that!

here we go,
this is a possible assembly, i am not saying it is an easy thing to make but it would give protection. it is not dimentionall correct, just an example.

first pic is both parts as they would slide past eachother

second pic os the bottom bracket that secures in place with suspension fork bolt going through it

third pic is the top bracket which fixes to the hub carrier with the ball joint thread going through the hole.
