No it's ok, thanks need all the help 

On the first point, Only the very tip of the lower bush made it through.

Using the genuine bush on the back row as a guide, only the black tip would make it through. None of the white collar made it though.

MaxTrac ones currently fitted, but as per description above, only tip made it through.

Concise information is what I needed so thanks for that

I have had similar knocking noises since fitting B4,s a couple of years ago. Im wondering if Im also missing the sleeves or similar.
I must check when I get time. Im curious now after reading this.

That's correct the white part is effectively a wear protector, with the spacer sleeve providing internal support.

The MaxTrac kit, whilst a fair approximation, is obviously not quite right as it still knocks... That said, if the kit wasn't fitted at all, or with key parts missing, there's nothing to say that the mounting hole isn't now over sized... In which case, you're 'dangle berries'ed.

[05omegav6]

By 'dangle berries'ed, I mean it will always knock...

I'm going to use the genuine kit tonight, spacer, discs etc. I took a quick look last night at the genuine spacers, they were black compared to silver, but they did look a tad ticker. 

Will compare the length of them tonight as well.

When inserting the MaxTrac spacer into the MaxTrack lower bush, it was a good fit, no movement. It all 'Felt' right. Thinking back though, the spacer on the shock went straight on, almost too easy. I remember doing the Estate shocks, fatty admin suggested greasing them to help it all together.

Took the 3.2 into the office today, such bliss, ultra smooth and silent. Auto and effortless away from the lights, much nicer to commute in...... hummmmmm

Worse case scenario is I buy another genuine fitting kit

Job is jobbed. All fixed and just as it should be now, using genuine kit. I think the disc + spacer on the MaxTrac kit are to blame, some photos....

The black spacer is GM, very slightly shorter.



A bigger difference is in the discs, note that there is no dip on the MaxTrac ones... (GM on right)



Not sure if it has an impact, but the spacer had a slit down it on the GM kit. Way it's made maybe?

GM



MT



The spacer in the MT bush was so loose I could lift it out...



Fitting the GM kit, the discs "felt" a lot happer sitting on top of the shock...



Lower bush with spacer



Inserted into the boot...



With top bush and disc....(before tightening it up)





So the 2.2 is back to normal now 

Thanks to Al for all the assistance 

[05omegav6]

You're welcome

All spot on from those pics

The difference in the spacers is indeed a manufacturing one. That seam is nowt to worry about, they really do all do that

[tunnie]

Good to know. 

What are your thoughts on the discs? Must be a combination of the discs and spacer causing the previous metallic rattle I had, but very pleased it's all back to normal now.

So MaxTrac kit close, but no cigar 

[05omegav6]

Indeed, the devil really is in the detail... the design and orientation of the washers focuses the clamping forces of the rubbers onto the turret whilst providing a solid mounting point for the shock rod Slight differences in the aftermarket mountings, even if visually similar clearly make a big difference... and if a concerted copy such as those Maxtrac items cause a knock, there's no way I would fit anything but the genuine mountings*...

That mounting essentially locates the trailing edge of the suspension arm, so requires just the right balance of rigidity and flex... the rubber on the bottom of the shock is where most of the give happens.

* clearly as long as the genuine bits are available.

[tunnie]

Given age Omega's are now, bits might start to become unavailable. 

I'm tempted to buy another genuine kit and stick in the garage, so that when the 3.2 needs them next in maybe 2 or 3 years i'll have a kit.

[GastronomicKleptomaniac]

Tempted to do the same, T, for that reason. I've just shelved out the garage, and am thinking of making into my own private Halfords...

For info I rang local dealers today ,as Al advised fixing kit for Estate is required with B4,s.

Kit is ....90487541..being for the Estate.No stock in Uk and will need to be sourced from Germany so 7-10 days and around £13.00 + per side 

[05omegav6]

That sounds a bit light... Individually the parts add up to nearer £40 part.numbers are discussed elsewhere... Test Zone or gen car chat
