Anyone know why this is happening? (Wishbone bush)

[JimsFR]

wishbones are polybushed front and back, rear beam has only just been done tho

My understanding was that unless they were all done at the same time it’s not good practice due to the existing rubber bushes having a different compound they then flex at different rates causing failure in either the new or existing bushes

Powerflex have responded and will replace the bush no quibble.

I think having the pressed arms and being so low is a bad combo all around so ill refit the bush, raise up 10-20mm and if it fails again go with something else entirely. Thanks for the suggestions chaps, will save this thread for in maybe a years time
