I had my 6.0L VXR checked out at AAS in Newcastle who carried our some work but gave me a list of other very important work that needed to be carried out, and until it was completed they advised not to use the car. It took a few months for them to source the parts but they couldn't do the work, the parts arrived and I got the track rod ends done but I'm struggling to find anyway able a willing to replace all the bushes with the new poly bush replacement kit ASS sourced.

The question is can someone recommend anyone capable of doing the job, not bothered about distance if they are good at what they do

Thanks in advance a very frustrated owner

What was the list of important work out of interest?
AAS don't usually shy away from work?

AAS are just snowed under, the critical jobs are changing the bushes on the sub frame that Stuart of AAS said were shot, but I bought a full poly bush kit through AAS but need some one to fit them.

AAS carried out a full check and changed all the engine, gearbox , trans oils etc.

Is that the rear subframe bushes then?
Yes AAS are pretty good, but always booked out!
I haven't used MWP personally, but I know a few on here have and they have a good reputation, knowing the Monaro very well.
I'd expect higher labour rates than AAS unfortunately, AAS are relatively cheap IMO.

Yes rear sub frame, although price is always a consideration, I'm getting desperate, the car is just sat there

Topcats, as already recommended also have a great rep, seem reasonably priced and very versatile able to engineer their way out of issues they encounter.

'Is there not a good garage near you that can swap the bushes ?
Im not a mechanic but am doing the whole back end re bush at the moment , Worse bit seems to be the need for an alignment cradle once back together but not sure if you can get around this by doing it one at a time??

Im attempting to make my own alignment tool as im also rustproofing the subframe , arms etc so the lot is coming off

Am following this thread with great interest, I am planning also to replace bushes with poly bushes.
As I understand if you were to do one at a time you won't lose the alignment probably not ideal or easy but on the face of it doable I think for me.

The question I have is on what part of the subframe is the alignment done? And which bush replacement causes loss of alignment?

The subframe bolts to the car with 2 big donut type bushes either side and the alignment issue will be here. Because the bushes allow some slight movement (NVH reasons), the frame could be bolted up 'skew whiff' not that you'd tell by eye. It must be bolted up perfectly aligned or else the rear axle will be 'out' and I'd imagine you'll get uneven tyre wear as a minimum.

I'd be interested in how you get on with this, mine was rustproofed but as some point things will need to be done again so it'd be good to have the DIY option smile

The thrust angle of the axle, you can adjust the error out to save the tyres but it makes the car feel weird when you let off the throttle (imo)

“Most” rwd cars don’t have thrust angle adjustment as the rear bushes have notches or grooves to line up when you install the bushes so they have to be pressed in correctly in the first place.

But sometimes there is a little wiggle room using the actual beam bolts before bolting up tight.

A lot of Fwd cars have pins to line up the front subframe after removal.

Bummer...I'll need to ring them sooner rather than later and see when they fit my car in for a service then frown

probably a different set up , but subaru have two extra bolt holes , it is simply a slightly expanded bolt that fits tightly through the subframe into an extra bolt hole on each side and that’s your alignment done , they are now sold as a kit to further lock the subframe down , as above make a similar bolt up and just do one bush at a time , is it 2 or 4 bushes , when done get the alignment checked see if it’s all ok , or you could mark and measure where the frame sits in the chassis so it goes back in the right place , on my cv8 i did the road response pack i can’t remember if rear subframe bushes were part of it ,the diff insert was good , if they were they would have been changed by me

Those were the ones I was planning to replace first, when I spoke to Roger at pedders he suggested I could replace one at a time and it would be okay, bummer that.

Out of interest how many bushes are there that hold the rear axle and can be replaced with poly? My sway bar ones are already done, these were done by the fish.

Think its the 2 main doughnut subframe to chassis.
2 on each suspension arm , although its recommended to replace one in factory rubber
Sway bar
and drop links.
And poly insert for the diff if you want to .

I think you will have no problem getting bog standard service but the poly bush change is a lot more time consuming

I have tried a few places, I'm not looking to get it done on the cheap just trying to find someone competent and also willing to take the job on. Again if anyone knows a good amateur mechanic with the know how and the kit to carry out the job please let me know
