from what i no polyurathene willl last a lot longer

but with rubber bushes you suposedly get more flex out of them personaly never had them but get told it alot..

[bad_religion_au]

i don't run bushes because they limit flex

poly because they last longer, and are more grease tollerant i've been told

rubberapparently gives better flex, never seen figures on the difference tho

[OISTA]

I've heard poly bushes transmit more vibration to other parts

[PJ.zook]

What about no bushes at all, would it be arite to just run tie rod ends on a custom 4link setup?

rubber all the way beter flex better ride and will out last that hard nolathane shit too. replaced the front and rear shackel bushes on dads cruiser before going to the cape rubber in the rear plastic red rubish in the front on greasable shackles rubber ran dry. got home and front bushes were rooted rubber looked like it had only gone around the block.

Soft custom made urethane Bushes

What i was told,

Uerothane are stiffer which creates better handling but give a harsher ride and more vibration and wear out quicker

Rubber are softer, give a nicer feel and absorb more vibration and dont wear out as quick.

I found this out after running all uerothane in my 4runner and wondering why they were starting to fall to bits after 3 months. SLowly going back to rubber


cheers

When i worked for ford the nolathane bushes used in EF XR8 lower control arms used to fall apart and completly seperate from the arm.
The fix for this was to fit standard base model bushes which are rubber and they work a treat , never seen a standard rubber one flog out like the nolathane does.
Better flex too

a little humur isnt welcom obviously...
Anyway go rubber, although dont get the rubber bushes that are "enclosed" in metal eg. rubber welded/glued to a large outer and small hole in the middle for a bolt hole, these type tend to tear.

nolathane are designed more for street racers where suspension travel is down to a minimum, why people put them in there 4wd's has got me. like GUHOON stated in the XR range they were fitted because of there "sports suspension" and they soon become noisy because there was too much movement.

are rubber bushes readily available...you guys have got me thinking about changing over to see how it goes.

Ah just the question I wanted to be answered today.
I had noelethane bush kit priced for the rear end of my 4runner (leaf) ranging from $18 to $22 a packet of 4 you need 12.
And then the flex question was raised so I priced rubber bushes, cheap chinese 1.50 each, toyota original part 2.50 each.
So now my minds made up It will be the rubber bushes they lasted 17 years in the 4runner so far and for the price of themm I can probably do the whole rig for the same price as just the rear with noelethane.
