Quoting CaterBram: Are they significantly better than the standard ones. ?
Don't seem to have any issue with degregation due to diff oil as i cured the leaks when I rebuilt the diff.
They're meant to last longer as they don't deteriorate when soaked in oil/fuel/Crossflow juice.
Those other examples of oil-tight motoring, Land Rovers, are also popular targets for poly bushes.
Beware though. They have far less give than traditional rubber bushes and might, (Pedants please note: might, not will) transfer more of the shocks and movement they're intended to absorb.
