You slid against a tree down the side of a grade, didn't you? LOL
About your bushings, with all the flex you were doing you were simply asking too much of them. Or at least too much for the typical poly most bushings seem to be made of. There are many grades of poly out there, different durometers, what's typically used to "stiffen" suspensions when replacing factory rubber bushings is obviously too hard for your application. Lower-durometer material could work good, and then of course there are the spherical rod ends that would eliminate the issues altogether. Are you thinking of doing what we discussed a while back and moving the arms to the inside of your current inboard plates, then adding new plates inboard of the arms, and finally using long bolts that go thru all three plates at once (with spacers between the plates where your arms currently reside? I think this will be the fastest and easiest way to fix the bushing binding problem and gain tire clearance at the same time. Should end up pretty darn strong too, as you're now spreading the load across three plates per side, not just two.
Been using Prothane and Energy Suspension poly bushings for years on all sorts of vehicles, never had problem with water ingress and deterioration. Actually I find that quite the odd issue, as when things are well greased during installation once the parts start moving the grease gets squeezed all over the place, thus coating things with a water-repelling film. I'm no chemical engineer, this is just my observations as user/installer.Also, underdrive, is there a good place to source poly bushings of different grades? It seems a lot of the manufactures pick a grade that they like and only use that. I know talking with clayton of EMF joints, the poly he uses is a water impenetrable, and as he explained it much of the poly tends to soak up water and break down, especially when adding grease to it. I honestly am not an expert on poly even the least bit, all i know was the stuff i had was pretty poor for my application.
Durometer (the measure of softness) and tensile strength are some of the terms automotive engineers use to describe properties of elastomeric suspension components.
Automotive applications should vary in durometer between 65(soft) and 88(firm).
Performance, heavy duty and off road tensile strength should not be less than 2000-2500 psi.
With most polyurethane companies it ends up being the lower durometer, the lower the tensile strength.
But with daystars custom compounds and in-house proprietary formulations, their engineers can now custom tailor the urethane properties in Daystar polyurethane products to provide the proper mix of strength and durometer as required by application.
RIDES BETTER, LASTS LONGER!
The suspension components abused by heavy off-road use, require good control.
In these off road applications, Daystar engineers specify a durometer of 80-85 to ensure good control.
Tensile strengths are achieved on the order of 5000 psi! to assure durability and long component life.
HEY!,
I will be interested in what you put in there.
For the in boarding your just trying to make more room for the tires at full lock?
Also sweet trail run, looked like fun!!
Cheers,
