See above for piccies and how to.

I tried his bush removal method I twisted the old bush about 180 degrees and it wasn't going to give in more likely to throw me across the shed!

As for alignment...the inside of the polybush is profiled so when the pin is inserted in will locate itself to the correct position, very obvoius when pressing it in.
After the bush and pin is inserted into the wishbone correct location is again obvious as the polybush lips secure over the ends of the wishbone.
The pin can rotate within the polybush (it should do). Just ensue it is refitted as it was removed ie correct side facing the subframe. Make notes of orientation before removing old bush. Sounds harder than it is.

Re driveshaft. Undo and remove driveshaft bolt and knock back the shaft back into the hub with a drift, so when the hub is move to allow removal of the wishbone the shaft is not under tension. I did not secure the shaft just held it towards the gearbox when i was removing the wishbone. It wouldn't hurt to tie some string from the outer cv joint to some anchor nearer the centre of the car as a precaution.
Pretreat the nuts and bolts with wd40 beforehand to make it that little bit easier.

Trust me it is easier than it sounds!

Some really useful info, thank you so much.

Interesting that there is some strap tool shown in the 'how to'.

Just checking which bolts need replacing, it seems that the one that secures the end of the driveshafts does, do you think its OK to re use the ones for the front bush (x2) each side that come thru the subframe ?

Is the wishbone hub/balljoint end easy to get off ? and does this nut need replacing also?

Am i right in thinking that with the new powerflex bush, you first fit the poly part and then drive the round centre bar through it?, seems from the description like it can be rotated once in ? or is it a much tighter fit than that?

Sorry for all the Qs, !

Don't need it at all, only of any use for a ball jount change only.

The drive shaft bolts are stretch bolts and should be replaced or at the very least use tread lock when refitting as i did. The other bolts can be reused.

Have known the tork head for the counter hold to give way resulting in a new ball joint, pretreat with wd40 clean the area and tap the tork tool in before undoing.

Yup, I fitted the polybush first the pressed in the pin, the pin can be rotated with a lever i.e. screwdriver once in.Sorry for all the Qs, !

Hope this helps

Would be interested to know others experience of the differences after fitting powerflex bushes, PFF88-601 is their P/N for the S60/V70 i think. What differences do you notice on uneven road surfaces or vibration when say acellerating or braking ?

Is the poly bush hard to drive into the arm?, according to powerflex you should insert the middle pin first, and then drive the bush in, the pin can be rotated once fitted (unlike the original bush where it is all moulded together and needs to be installed at the correct angle it would appear).

Hi there. I spent 3 hours trying to fit the powerflex bush to an arm last week only to find that the pff88-601 is designed for oil filled bush repacement only
My metal centres are solid straight bar type with no waisting in the centre.
Can anyone tell me the diamter of the centre swage and the length of the waisting so that i can get them machined down?

Many many thankyou's to anyone who can help......

Hope this helps others and sorry for the tangent on this thread..

Hi Cherry,

Interesting to hear, talking to powerflex last week they said that some manufacturers original bushes have voids in them (im not sure if you can see these) or whether they are hollow/hidden sections within the bush that give more flex in one direction only. Someone else mentioned that volvo had changed the bush style during the history of the S60/V70. I hadnt heard of oil filled bushes but maybe this is what the voids are filled with, I wonder if the original bushes were solid and later ones with voids for reduced vibration. Could it be the original bush splits and the oil comes out? Makes me wonder if the gap (in the vertical sense) is where these voids are (see original pic i posted) would be interested to hear if anyone knows if there are different versions for earlier cars? Has anyone got a low mileage car where the bush looks 'solid'.

In the link, there are piccies of the oil bush and the waisted area of the metal centre. The powerflex bush has extra material to go in to these areas, thus giving it the correct torsion.
I have an early p2 v70, which, on consulting with volvo, do not come with oil filled bushes.The metal shaft is one thickness along where it comes into contact with the bush.The bush looks the same for both types, just the bar that is different.
I need some measurements to create the correct bar to go with the powerflex bush.
The original bushes in mine were volvo gen parts.
