…. Clue: it’s number 2.
were those bushes pre-fitted when the shock arrived or did they came in a bag?


why i ask this:
sometimes the sleeve supplied is not manufacured in the correct length, referring to the width of the eylet inside the shock or a inside a wishbone.

means, once the 2 halfs of the bush have been fitted to the eyelet, the sleeve is than too short, even it looked to be ok pre-fitment.

and in most cases its necessary to bent-open the chassisbrackets b4 installing any newcomponents.

Pre fitted apart from the new ones which were loose. It doesn’t make much difference as the material is at least hard enough to tell you if it’s not inserted enough as it wouldn’t fit between the brackets.

And as for bending the brackets - not too sure where to go with that one apart from:

DO NOT BEND THE BRACKETS IF IT CANT SNUG FIT BETWEEN SOMETHING ELSE IS WRONG !!

One Mistake often made
Tightening up bolts on running gear while in the air and off the ground.

Both shocks and wish bones should be done under load on the ground with the full weight of the car.
If tightened before they will be under greater compression and very possible another cause of failure

Whilst that might be good practice for bonded rubber bushes it is not necessary for poly bushes.

I have to ask - what does the photo show?

AVO have recognised there is an issue and are actively looking at a bonded alternative. Hopefully it’ll be a retro fit press in bush.

I must say they can’t be faulted for their customer service and taking the issue seriously. Really excellent.

In the meantime anyone about to fit a set of shocks is best leaving it for a couple of months awaiting the upgraded bush.

That sounds really good. Thx for sharing . Any chance you would be able to let us know when these are available to save us individually chasing AVO for updates?

^ Of course, but obviously the more nudges they get the better.

The most important thing is they recognise there is an issue with bush failure. As I’ve said previously many people will be unaware the bushes have got play or gone oval unless they’ve stripped them down as it’s not necessarily visible.

If AVO are looking at a bonded alternative (rubber) then that means we have gone a full circle🙂
The original bonded rubber is better😏

Well I have been working with Avo on making some changes.
Although I have not had issues but some have.
I order to be reactive to needs I have the first set of new Avo bumpers with altered new bush set up on there way for this Vixen S4 I am working on

^ I should imagine that’s going to be too hard a ride for me but do they need a press to fit or a thumb?

That’s press fit, the question was if they weren’t there’s an issue.

They don’t look that great tbh as it’s made up with a sleeve to get the bush to work.

So they had the chance to run a load spreading fully bonded metalastic bush and instead have gone with this ...?

AVO are using larger eyelets with fully bonded bushes on new stock so good news, until then and for retro fit there’s this 3 piece setup.

AVO bushes after 1500 road miles, they’re split and oval. AVO say they’re the current bush and ‘a few people have had problems with them’.

Anyone on here had issues?

Yes my AVO bushes have all self destructed also. My AVO's seem to be a built to a budget, low quality item. The adjuster knob is terrible to use. Until you get to approx 7 clicks it is totally smooth with no noticeable click. This makes them impossible to balance equally on a soft to medium setting.

On the positive side they do feel OK from a driving point.

I would prefer to fit a set of better quality shocks such as Nitrons but I've never been able to get hold of the correct specification to give to them.

Moto
I believe that Adrian Venn supplies/stocks the correctly specified Nitrons.

By the way, have you thought of casting your own urethane bushings?

Thought about having something a bit harder turned up, however AVO have now supplied a set of their 3 piece retro job and in fact the outer is hardened steel and the inner a decent bonded bush so it may well be effective. I havent tried the outer for size yet so just hope its a tight fit.

Interesting idea though, not tried casting urethane so probably not a good idea using bushes as the learning curve !

I didn't think Adrian@ ever supplied Nitrons for Vixens but hopefully he'll let us know for sure.

I'd be interested to get feedback from anyone running the upgraded AVO bushes as I'm planning to get mine done next month.

I’ll let you know if I do mine, but I fitted the first set of like for like replacements I got from AVO and can’t summon the desire to go through it again despite knowing I’m on a path to doom. Gates barricade hoses are the next job.

So if a rubber bush is used the mount ends should look similar in design to the picture below

If a racing type damper is used then the correct rose type bearing is the fitting to use as in the picture below. Excuse the rusty chassis
The captive vulcanized rubber version in steel is available in a variety of sizes from Ikon/Koni. The rose joint version should be available anywhere nice grade hardware is sold. I like McMaster-Carr and Midwest Control, in the US.
