Michele Posted August 22, 2005 Share Posted August 22, 2005 Well,it was time for me to experience some issues it seems... Some of you may remember I fitted my RR HD (red/white) springs a while ago,as DD did before me (I have yet to get longer dampers to match but...). These gave my 90 a nice lift,even with my winch & bumper fitted. I first had some bad annoying vibes until last Saturday when I finally fitted Land Rover spring silencer plates (from Discovery # ANR 2938,I have the label somewhere)to the front. The bad vibes are now gone (this is probably the cheapest alternative route instead of a DC shaft). These isolators add barely 1 cm more of lift (uh-oh)... The Cube is quiet as before,but! I found myself scared to death while on tarmac, as sometimes (I think when the pavement has some irregularities,corrugations,cracks,whatever) the steering starts shaking as mad! I mean it shakes so hard it you can literally feel the whole truck shaking! I thought I was about to loose another wheel (some may remember) and stopped one side, but wheeels are ok as the steering etc. Now what? I know with a lift the front roll center is raised because and more "darting" about on the road in response to road irregularities...but this is too much! Cranked radius arms jump into mind,but I can't afford now. I have a couple of o.e. arms from a 1986 90 Diesel Turbo laying in the box I could sacrifice and try to bend in a workshop...just need a precision press and someone who knows what to do...but... ...I don't really know... So...thoughts? The Cube handles fine and go straight if I leave the wheel,is quiet as before. It's just this horrible shaking which worries me. (SOB) TIA... P.S. Went out for pizza and a Guinness these evening and while getting back some shakes woke up a friend of mine who was almost sleeping...

western Posted May 7, 2007 Share Posted May 7, 2007 Have you cured this shaking yet, could be swivel pin preload isn't correct. Quote Link to comment Share on other sites More sharing options...
steve b Posted May 7, 2007 Share Posted May 7, 2007 As Western says check swivel preload , also check steering damper as any reduction in damping efficiency can create "steering shimmy" which is what you describe. Worn panhard rod bushs add to it. HTH Steveb Quote Link to comment Share on other sites More sharing options...
