No.... the Stilo rear axle bushes are a special oil filled hydraulic bush. Sometimes, the first sign of them going is oil leaking out onto the ground. They have to be able to twist and compress as the suspension rises and lowers so solid poly bushes would not be suitable.
Shop4parts have them for £17.47 each
