ED suspension rubbers/bushes
Just an opinion of mine in the last 6 months on my ED Falcon suspension bushes.
This is for those of you have either converted or wanting to convert to Poly, Nolathane and original bushes for the EA-ED and etc.
About 6 months, I replaced my lagging and worn out suspension rubber bushes (all of them), relating to the front suspension only.
Went and bought a $165 kit, which was Poly Bushes made from Mackay Ind.
Thought OK, different composition, see how it goes.
Installed them, which was quite relatively easy to do, just dismantling and assembling the front struts area was the pain.
The quality wasn't that bad at the moment of installation, but until I used them for about 1000k's I got a bit weary of them.
Replaced the bushes on the front stabilzer arms after 1000 k's (Control arm to Stabilizer Arm) and the chassis to control arms with Nolathane, because of better quality in the harshest areas.
Just about 5,000 k mark from the installation of these poly bushes, it loosened up so bad, that the suspension went really loose, felt like a V8 Supercar with a broken Watts linkage in the front.
Replaced the mixture of Mackay Poly bushes and Nolathane bushes, with original Ford rubber bushes.
Had a look at these poly bushes after removal, and they had worn/conformed to a different shape (as I expected).
But the differences in specs (sizes and thicknesses) is remarkable.
Poly bushes had about 1 mm interference fit. Original bushes had over 3-4 mm
fit, which is what you aim for.
Hence, they are a bugger to install.
Because the Poly and Nolathane bushes push in by hand, there is no strong interference fit as per se.
With the original Ford bushes they use the inside surface as an interference fit (you have to use either a press, or bolts used like a press, to get these bushes in).
Yes, it did take longer to put these bushes in, but the result speaks for itself.
The front chassis rubbers are a bit more difficult to put in, with the limited space.
All bushes were installed with a bolt packed with washers and spacers, and using the thread as a "press". Just wind it up and in she goes.
I also did use proper "rubber grease" to assisit in installation, just don't use to much, little bit on the edges thats it.
It's a much more noticable difference in putting the originals in, than these poly's.
I feel a lot safer now.
Does anyone have any other thoughts in either direction?
Just, I have had this idea that the Nolathane were a better type than that of the rubber bushes, but now I have swung back to the originals.
