Front lower arms experiences

looks like a nice job, did it come as a kit with the bolts and everything included, or did you purchase those separately. I agree about the cracks being down to corrosion of the inner bush, i have removed a couple of cracked suspension arms and both had badly corroded inner bushes (i live near the sea).

Every year take the bolts out, clean, heavily grease and re assemble.

The only issue I have with the corrosion theory is when mine cracked the bolts came out easy. I feel there is also a leverage thing going on when you hit potholes.

The only quite anoying colateral effect is that I have the suspension error light on since then. It seems it didnt like the operation... everything seems ok when driving but the light.

The bolts don t come with ES (buth the bushes yes) I bought them at superformance.

Btw : absolutely no crack on my old wishbones, and the bushes look almost new after 84000km in a dry environment (south Italy). It might confirm the rusting issue.

I also wonder if the fact that you have to shim these arms into place means that you can also shim them into place and put large off centre forces on the bushes? Is it possible that in the process of shimming these to get the elusive alignment right you can put enough offset on the axis of rotation to create forces that can split the arm? This has bothered me every time i replace or re-fit one of these arms. I personally try to make sure the arm is free to move before i tighten any of the bolts, but its a tricky thing to get all 8 like that and get the alignment and the camber and all that!
