just recently had all 4 spring shackles on my HJ61 replaced and mechanic at the time strongly advised me to use the pvc type ( cant remember correct name ) which i did . But recently when in Warrnambool Vic had to get shackle replaced on my old van and reputable mechanic advised me to use the rubber ones . Comments please ??

Rubber, the urethane bushes, are stiffer so the ride will be slightly worse as they have no give, they will wear out a lot quicker and they will "squeak". they are also dearer.
I have owned 69 cruisers and I will never use anything other than rubber again, this includes in control arm bushes in later cruisers.

Have been using nylon type bushes for years and have found them a better stiffer bush but high wear rate on some vehicles. Therefore I tend to use rubber bushes on things like shackles on off road vehicles and tradies utes. Personally my patrol runs the softer nylon bushes and have had no problems in 105000 km bot used rubber on my cvruiser .

I had the front springs replaced and upgraded 1 leaf (rear done a while ago) on my HZJ75. I tried the polyurethane or whatever greaseable bushes with new shackles etc just before our latest trip.
After about 21,000 k's including the GRR I have found the front bushes have a hell of a lot more wear than I would have thought possible seeing as how the originals did about 280,000 including the CSR.
The grease gun was applied several times during our trip. Thinking about either going back to the standard Toyota offering or maybe some other greaseable material.

G`day Brian,

The Plastic/Poly type, especially Piddlers, are rubbish compared to the genuine Toyota Rubber ones.
I was forever changing the pretty ones until I was advised to change to Genuine Tojo Rubber.
I have done heaps of outback trips since and still on the first lot of rubber ones.
Not cheap but worth the extra $`s

Note.... They MUST be the Genuine Toyota for the best results.

Just MHO.

All to do with the DURO [SOFTNESS RATING ]
2 bushes the same colour can be a different hardness
Most ""plastic "bushes are way way to hard causing huge amounts of wear on shackle
All must be periodically greased . Mostly never happens

In my experience around 30yrs , the blue bushes available from Fulcrum suspension . I cannot speak highly enough . Way way better than any other bush period .Many years of using them in the mines .These cause little or no wear .
We always replaced the new after market shock bushes with these.

The background is they Fulcrum purchased a company called Super Pro at least 15-20 yrs ago who only made bushes in about 6-8 different hardnesses .

Go rubber they last a long time and the polly one's will wear the bolts out as well if not lubed properly unlike rubber and yes it's hard to believe such a small thing will make you feel even more bumps which you don't need with a leaf sprung truck but they certainly don't help the ride..
