bosozoku_gx71 Posted November 7, 2012 Share Posted November 7, 2012 Hey guys, just getting some bushes made for my gx71. Have bc golds etc and its horrible on the old bushes so im getting the entire rear end made up in polyurethane but im just not sure what stiffness i want to go to. Obviously most people get red ones but is there much of a difference between red and yellow. Anyone with experience with either would be great to know what you think.

flyingbrick Posted November 7, 2012 Share Posted November 7, 2012 expect an increase in road noise and rattles- but much better feel etc obviously. I have only ever used red but hear there might be better materials around now that last longer. use lots of grease! Quote Link to comment Share on other sites More sharing options...
J-Calico Posted November 18, 2012 Share Posted November 18, 2012 Doing subframe bushes? Any available off the shelf? Or using Ronnie? Guess those solid alloy ones readily accessible for nizzans just be rather bone jarring.. Quote Link to comment Share on other sites More sharing options...
KKtrips Posted November 18, 2012 Share Posted November 18, 2012 My understanding is the colour is brand specific rather than an indication stiffness. If they are an indicator then I have no opinion as I've never noticed a difference. But as said above, make sure you use plenty of grease on assembly. Otherwise you will end up suicidal with squeaking. Urethane bushes suck for noise. I despise fitting them on my cars so if you are eating bushes then I would spend some time trying to figure out the cause of that problem rather than just replacing them with harder bushes. Example when you are fitting the bushes, are you tightening the securing bolt with the suspension at droop. Problem with that is you are pre-loading the bushes once the car is sitting at ride height. Which is exaggerated in a slammed car. Best practice is to tighten the bolts once the suspension is settled at its road ride height. There are possible other reasons like alignment and so forth but you may already be committed to urethane which is all good. PS - use plenty of grease.

Testament Posted November 18, 2012 Share Posted November 18, 2012 just regular grease? or nickel antiseize? What you be your recommendation KK? Quote Link to comment Share on other sites More sharing options...
KKtrips Posted November 18, 2012 Share Posted November 18, 2012 Any grease is good I guess - but the stuff that comes with it is good - I have been told before (and consequently used) that CV grease is the same as urethane bush grease.

cubastreet Posted November 18, 2012 Share Posted November 18, 2012 also make sure that whatever moves inside the Bush is nice and smooth cos if it's all rough and rusty the Bush won't last very long Quote Link to comment Share on other sites More sharing options...
mjrstar Posted November 19, 2012 Share Posted November 19, 2012 The bushes i got from summit racing came with some uber sticky grease. I can't say i see how any more than a even film of quality grease would make much difference. If they are binding then i would suspect an issue with the length of the inserts?

flyingbrick Posted November 19, 2012 Share Posted November 19, 2012 don't just use any grease. it may eat or dry out the urethane. Quote Link to comment Share on other sites More sharing options...
Rookie Posted November 19, 2012 Share Posted November 19, 2012 ^ huh, then why do they supply you with grease normally? Quote Link to comment Share on other sites More sharing options...
Steelies Posted November 19, 2012 Share Posted November 19, 2012 he means use the correct grease, ie the same type as the stuff you refer to. Quote Link to comment Share on other sites More sharing options...
Rookie Posted November 19, 2012 Share Posted November 19, 2012 Oh sweet, I dunno what sort it is you normally get, but every set of poly bushes I have bought have come with a little sachet of grease. Quote Link to comment Share on other sites More sharing options...

SHGWAG Posted November 20, 2012 Share Posted November 20, 2012 I'm pretty sure the manufacturer would supply you with the correct grease. Quote Link to comment Share on other sites More sharing options...
ryanfels Posted November 20, 2012 Share Posted November 20, 2012 I'm pretty sure the manufacturer would supply you with the correct grease. Hes not getting off the shelf bushes so they wont come with grease Quote Link to comment Share on other sites More sharing options...
SHGWAG Posted November 20, 2012 Share Posted November 20, 2012 Oh, in that case contact one of the bushes suppliers and ask what they would recommend? Quote Link to comment Share on other sites More sharing options...

AllTorque Posted November 20, 2012 Share Posted November 20, 2012 - I have been told before (and consequently used) that CV grease is the same as urethane bush grease. Thats what I have been told also. CV grease is 'rubber safe' so it doesn't cause it to swell or perish. Quote Link to comment Share on other sites More sharing options...
