Was only joking. I'm sure I can figure it out

Also worth taking in to consideration is what ride quality you want (if this is important), after-market arms will give different results to genuine ones.

I doubt anyone is likely to notice a difference in ride quality from wishbones on a softly sprung, heavy road car!

Did i hear on here some disappointment on wishbones being poly'd , hash ride compared and what about wishbones failing due to the fitting of them

Wishbone failure from.fitting poly ONLY refers to the replacing of the vertical bush with a poly improvisation. Replacing the front horizontal bush with polys is a well trodden and perfectly safe path.

As to ride harshness or not, that's a matter of personal preference. Any doubts then either drive a car with them fitted or don't bother fitting them... Personally, I prefer the lack of wishy-washyness that the original bushes have built in...

As for the difference in feel between genuine and pattern, pattern are a touch lighter, reducing unsprung weight... But as Nick so succinctly suggests, on a two ton road car, it's all rather irrelevant

As you only poly the front bush there is no real noticeable change in ride. The only thing that I noticed when I did mine was that a slight wheel imbalance was highlighted, whereas before it was disguised by the soft rubber bush. A proper wheel balance eliminated this though. 
Mine have been in a long time now and I've since refurbed the wishbones using GM vertical rear bush and they appeared to be fine stress wise.
I believe the failures were down to stress/fatigue caused by a poly rear vertical bush, which in fairness, the members who were trialling them stressed were an experiment.

On standard suspension there is definitely a difference, with the genuine arms majority of any resonance is taken up by the bushes, they were designed with this in mind, and it works.  On a like-for-like setup you will feel more through the steering wheel with after-market products.

If you mean by virtue of the fact that they have oil filled bladders in the front bush, guess what, so do the arms/bushes supplied by ATP...

Still doesn't justify the price difference either...

That's good at least they can be obtained via other means because it's worth it.

Have ATP on all three cars..  all good

We often chat on here about replacing these arms because of the main bush failure.....nothing mentioned about replacing the ball joint or the other bush...is this because they very rarely fail ?

There are two approaches...

1. Refurbish original arms, assuming they are straight and fit for purpose, using genuine/poly fronts/ genuine rears/ new ball joints.

2. Fit cheapy replacements such as those I linked to, stupidly good value for money, and treat as a disposable service item.

The third approach is 2. But swapping cheapy bushes for those in 1.

[05omegav6]

You also need to be realistic about the life expectancy of the wishbones...
Whilst genuine wishbones which are sound and true might seem viable for refurbishing, wishbones vary in build quality... And bushes can deform if not precisely pressed home, shortening their life...

Whilst original wishbones last 80-120k miles, even genuine replacements are unlikely to hit 80K, which makes a mockery of the fact they cost over ten times more than cheapy ones which should last 15-20k miles. Even allowing for the geometry costs, replacing like for like cheapies on an annual basis still far better value cost per mile than messing around either refurbishing or going genuine.

What about the Monaro
