BogMonster Posted August 10, 2005 Share Posted August 10, 2005 Just been looking around to see if Polybushes are available for Defender shock absorbers ... the particular type I am after is the bottom bush for the rear shockers on my 90, they are the new type big "cone shaped" bushes similar to those found on the back shockers of a late Discovery Tdi, genuine part number is RNF100190L I think. Has anybody used Polybush shocker bushes and are they a lot harder than std? I am pretty sure my lower bushes are what is causing the annoying knock in the back end of my 90 when I hit small sharp bumps at speed, if you lie underneath grab the rear crossmember and pump the back end of the vehicle up and down the bushes have a lot of flex in them, too much it seems, but I had a look at some new bushes (was going to change them) and they don't seem to be any better - they seem to be far too soft rubber compound for a bush. I think something a lot harder would be better - the old type bottom bushes (552818 as fitted to older 90/110/Defender rear shockers) allowed no movement in the shock relative to the axle bracket at all, these things just seem a rubbish design. Feedback please. I am getting a set of Monroe gas shocks which may well come with better bushes, but they are a couple of months away yet (drawback of living in this part of the world!) and the knocking is starting to get well over to the right hand side of my irritatometer also if the Monroes only come with rubber bushes I will have the same problem Ta Quote Link to comment Share on other sites More sharing options...
