I have got a 54 plate WRX and there was a knocking noise coming from the rear offside strut. I took it into a garage and they said the strut top mounting was cracked and changed it. It was fine for two days until the same knocking noise came back.

Can anybody help? Is this the shocker gone. If so, if I replace one, is it advisable to replace both at the rear?

Cheers

 

shocker is knackered mate

 

Cheers Phil,

I have only had it two weeks. Having read deeper into these threads, I now know its a common problem.
