Talking Pictures of damaged 4 link rear suspension.....

Hello all.
My POS is going on a diet.
First: She is being chopped and we will take away a lot of tube and sheetmetal.
Second: I am working on the design (center of gravity, instant center, etc) of her new 4 rear link suspension.
Rear leafs will be taken apart, Gas tank relocated, etc.
I have done my search and I think I have all the measures I need. I see everybody is happy with their own designs, but...... what about the failures and pitfalls of this 4link rear suspensions?
Does anybody have pictures of broken 4 link suspensions? If don't, which are the real life con's ?

Holy shit son! How much that pig weigh? Surely you didnt think ALL the tube was nessicary did you?

As for linking the rear.... as always failures come in many forms and many ways. However, I dont often hear of a 4-link failure. What exactly are you thinking will fail? The design itself?

If in fact it is damaged usually its the builders fault, or because too much is being asked of the material. What Im saying is, either a weld fails or material bends. Also, Ive seen plenty'o rear trusses ripped from the axle because they are not properly braced or built. Make sure your welding is damn good, choose strong materials, and brace things well.

How are you intending to design said 4-link. Will a calculator be involved? Is this your first time builing a link suspension? The design of the suspension can reak havoc if its not properly done right. Not just from a riding/ performance standpoint, but also placing a few wrong things in a few wrong locations can make forces increases significantly. Thus your supsension takes those forces, resulting in breakage.

What he said. Failures are from inadequate welds or inadequate design or materials. Make it strong, and weld it good. Most guys don't post pics of their fuck ups......they just fix it.

I've seen mounting brackets rip off, tubes that mounts are welded to bent, and welded inserts break out of the link tube. Don't just build it casually and assume it's good, think about the stresses and the build quality.

One of our f'ups about four years ago on my ZJ front four link. 2nd trip out. Guess this link wasn't welded all the way. Drove it back to camp with the straps how they are in the first pic.










And the fix. Didn't happen again and had many of beatings on this ZJ.
