Hi guys
I am new to this forum and need advice ......I have a 2011 extra cab 4x4 with 160 000 kms on the clock ( I am the second owner ) and its time to change Shackle bushes , I can see they are worn and Toyota workshop( after last service ) also recommends its time to replace .
My question is rubber bushes or polyurethane ??????
I have been reading some Aussie threads and there seems to be a huge debate as to which is better , some say the poly bushes are to rigid , they make the ride even harder and are not good for vehicle components as they are to hard , rubber bushes have more "flex " therefore better for your vehicle and give a better ride .
I phoned 4x4 Mega World for price on Old Man Emu bushes ( just to get an idea of cost )but they wont fit my stock standard springs , cant afford to change the whole setup at the moment . So is it better just to stick to standard rubber bushes from Toyota ?
I have stock standard suspension , I do weekend camping and 4x4 trips but mostly the bakkie is used for work .
I would appreciate feed back / advice on this topic

Thanks
Guy

Replace with OEM, i did mine this week. I have a 2011 S/C 4x4. I agree with the poly bushes to be too hard. It can cause vibrations and all sorts of funny stuff.

I have installed Vesconite bushes on my SFA a couple of years ago. It is a local product that is used in the mining industry.

Polybushes.

It is really not much harder but will last another 100 years! My Hilux drove at least 300 000km with a set without any issues, vibrations or harshness.

Order direct from the factory - last time I paid sub R200 for a set!

Also running on their polybushes for the lower control arms. Quality product locally made and well priced.

I would not be surprised if the guys from Mikem also use them for their suspension kits.

Not sure if it's been said but.... if you want more flex... go with rubber... if you want softer ride... go with poly

Excuse my ignorance Cassie but how do you figure that poly gives a softer ride?

Poly bushes are softer than rubber. They isolate you from the axles to body vibration due to them being a bit more flexible.

No Sir! Not so. Rubber is the softer material. The practical experience I have is convincing for me but I cannot pass that on.

This is a good article if found.

Also use poly bushes and have no problem with vibration or hard ride. I doubt that the bushes can cause a hard ride. Your springs and shocks play a much bigger role in ride comfort than the bushes.

Before you posted the question I did not even know there is a difference as I could not tell a difference when I took out the OEM rubber and replace it with Poly. All I know is the poly lasts 5 times longer and in my opinion rubber is crap.

Rubber is crap yes, but it is softer and depending the aplication there is still place for it.

Fit those poly bushes to a 105 series cruiser and you crack the diff mountings due to lack of flexibility.
Some hard lessons learnt in that case and poly definitly not a replacement in that specific case. In shackle bushes i would definitely fit poly .

Polyurethane bushes that get sold over the counter has a harder compound than normal bushes.

However if you can have your bushes custom made it can be made to a much softer compound.

Will ask Darrell and see what he says.

Marius, agree, will use poly on shackle bushes and stabilizer arm bushes, but for the rest I stick to rubber.

You can also get them at Midas (Bowls Rd. - speak to Sean or Vincent - speak to Andrew or Dean) or at Autozone (speak to Trevor). :winkx:

I used to think that poly was the better option and lasted longer but I'm not so sure any more. The rubber used is a pretty hard compound, but still has more flex and ability to compress than poly IMO. I have already had to replace poly shock mount bushes that couldn't handle the harder shocks and just disintegrated after a couple of years. I suppose it really does come down to the specific application.

Is this a DIY job? Or do you need a lift. Toyota said my rear shackle bushes are finished and need to be changed.

DIY - jack up rear of chassis so axle hangs in air, tyres off and under for safety, lightly support axle from below, pull off shackles , replace bushings with liberal amounts of grease. Look at downloadable manual on this site, older model, same procedure, most likely similar torque specs.

Do the fixed ones first, then the hanger side. That way getting everything lined up is much easier
