Tony.

Thanks for the tip! Certainly something that needs thinking about........

I did just reinforce a new set for my new project daily. I will post some pictures this week and these stay ok.

Ok thanks Jeroen!

Ive just done the rear arms on mine - there was no welding at the points mentioned, just a smooth pressed flange. Surely though, the damage to the arms in the photo is nothing to do with the bushes and everything to do with having over-stiff suspension? All the loadings from the axle to the spring get transferred through that small part of the arm, if the suspension is so hard that it cant compress then this is exactly where the arm would bend and exactly the damage i would expect to see.
Matt.

It's the left to right twist that tears it, not the up and down movement.

I dont agree - sorry. Looking at the photo thats not a "twist" failure, its a straight overloading failure. No evidence of twisting.
That arm has been overloaded with harsh use and over-hard suspension.

I totally agree Matt and I would recommend staying always below 200 lb inch and no more than an inch lower.

I also prefer the voided style of front bush if you can find any.

Has anyone looked at the end of the suspension arm where it goes into the axle,
If its shiny and the axle bracket is the same that may be the problem esp on lowered cars

I cant say Im surprised metal components that are 30 years old fail especially when you are driving the car beyond the scope of what it was designed for.
