No longer available from VX any idea where else might do them?

Have posted a wanted add if new aren't available anywhere...

[chrisgixer]

A rare failure, approaching 200k miles and jacking on the dif kills em.

So should be some good ones about. I woodafunk.

[Kevin Wood]

Hmm. Need a look around the back end, myself. My car has developed an "interesting" handling characteristic.

[05omegav6]

A rare failure, approaching 300k miles and jacking on the dif kills em.

Would like to think so

As a thought would Carlton/Senny ones fit...

[05omegav6]

Hmm... My car has developed an "interesting" handling characteristic.

That's more or less how Chris phrased it the other day

[Kevin Wood]

Right hand turning is fine. Roundabouts can be hoofed around with no problem. Load it up on a left hand turn, however, and it's all fine up to a point, then you best be ready with an armful of opposite lock.

In fairness, it's just had rear tyres and I haven't checked if the muppets have inflated them correctly.

Did you keep my old ones? If so, ex taxi al is welcome to them

[chrisgixer]

Gives a tucking feeling from the rear once it finally goes? Without loosing traction?

Yours, could have fed 5000 they where in that many bits. well, at least 4 seperate parts.

[GastronomicKleptomaniac]

Topics like this remind me that I need to go mad and buy a load of new bushes to do mine from front to back...

[Mr Gav]

I`m afraid the diff mounts to the Carlton/Senator aren`t the same. Besides they fail earlier and you can`t get them anywhere new

Might have a lead...

[andymp]

I'm after a pair too. Theyre like rocking horse s@#t.

[chrisgixer]

hmmm, might have to nip down the brakers

[chrisgixer]

Although surely Steve at Heathrow is a good bet?

[chrisgixer]

or cut the rubber out completely and replace with a lump of poly?

I guess poly could be fairly crude, and be a solid lump, but would have to go all the way up to the body enough to be tightened in, so to speak....or would that transmit noise?

[05omegav6]

Thinking that through... Given the rest of the suspension is poly nothing to lose...

Exactly how much space is there between the bush and the floor

[chrisgixer]

think these are they

shown upside down btw

[05omegav6]

Hmm nothing in pigeon german about two of them... Might be able to do summat with poly

[chrisgixer]

monaro?

[05omegav6]

Another question for Monkfish...

Standard Monaro has a single central mount, different design rather than one Omega mounting

However, Harrop diff cover has a different set up, so might be mileage there...

[chrisgixer]

Early models? there's poly inserts involved somewhere along the line 

[05omegav6]

Early models? there's poly inserts involved somewhere along the line 

Only on standard diff cover. Similar design to Omega but has 2 bolts to the diff instead of one

Cars with Harrop diffcover don't use the original mounting, but I don't know how the diff is supported on such cars... There might be potential, but need to ask someone who knows

[Kevin Wood]

Gives a tucking feeling from the rear once it finally goes? Without loosing traction?

I suppose so. Not sure if it loses traction at the rear, but if not, there's a sudden application of rear wheel steering. That's what it feels like, anyway.

[05omegav6]

With a fair sized dollop of body roll for good measure

[Kevin Wood]

Not sure. Have been to pre-occupied in gathering it up again so far.  Might need a trip to the airfield.

[05omegav6]

Nolathane 49156 might work with tweaking

Pedders do one too, EP1156 I think, but the search function on Aussie site doesn't show pics, and the UK site is so shockingly poor it won't even entertain the part number

Have another idea in the pipeline... shall report back once done, broken mountings gratefully received btw

[Nick W]

As a temporary measure, can't you degrease the best ones you have, and fill them with silicone to tighten them up a bit?

I tried that with sikoflex on rear donut voids. Failed as far as bonding goes, and that particular sikoflex, what ever it was, was way too soft once set.

Although I didn't roughen the surfaces so can't be certain, but I doubt it would bond, from what I saw?

Yes that's it, summats busted.


....Is it your poly donuts I have in the garage still?

Just to add, Als felt loose when weaving within a lane. Feels like the rear axle articulating like a trailer in place of the rear axle. Not nice.

[robson]

If these are unattainable should we be looking at having some made up by a rubber company or are the so seldom used that it would proove too expensive,I have an old MG and some bushes are only available because a specialist rubber co has been used to replicate.

[05omegav6]

Pattern ones don't exist and GM discontinued them in November last year

I am looking to strip mine to the bare metal components and re mould them in 68 shore Poly...

Will know how that goes by this time next week hopefully

Yes possibly.

But If making parts, I'd suggest poly would be preferable...? And cheaper, assuming a full size insert to the existing u shaped bracket is viable of course. ...as rubber parts involve bonding to metal work which also needs to made.

[05omegav6]

Was planning to strip all the bonded rubber from the bush and using the U shaped bracket as the mould with the support block positioned in the correct place, and the pouring the Poly in and leaving to set.

Should ensure no voids, thus supporting the diff much more effectively

[sjr47]

A few years ago tried a temporary fix on one of my primeras engine mounts using Devcon Flexane Liquid Rubber compound still going strong today & passed 3 x MOTs comes in three different shore ratings belive I used 80 shore not cheap though about £50 notes plus cost of a primer for metal bonding if all else fails might be worth considering.

[robson]

Sounds like a solution

[chrisgixer]

[Mr Gav]

I`m getting similar symptoms, usually in left hand bends, ok to a point and then it gets more body roll and breaks traction on wet roads. It was like this before I put my poly donuts on and it hasn`t improved since i put them on.
I think I`ll drop Steve a line and source some second hand ones until a suitable solution is found.

Worth a visual exam first.

[Mr Gav]

Worth a visual exam first.

Thats next on the list when the weather improves and I`m not working, I also want to inspect the rear dampers too.

[Kevin Wood]

I'm starting to wonder if this is a failure or just monumentally bad tyres of F***en proportions.

Anyone tried KU39s on an Omega on 235/45/17?

Will get under it and have a look at the rear bushes later in the week though.

[05omegav6]

This arrived just the noo...

so shall have a go today

Make that the second dry day next week poxy weather

At least I'll be able to do the shocks at the same time...

[Kevin Wood]

Is it a good time to mention that my cousin runs a rubber company?

[Mr Gav]

I'm starting to wonder if this is a failure or just monumentally bad tyres of F***en proportions.

I think bad tyres exaggerate the problem, I had some cheap crappy ditchfinders on that came with the car, downright dangerous in the wet. Goodyear Eagle F1`s have helped but not cured, so that leaves diff mounts, rear wishbone bushes or rear dampers.
I don`t think it will be the void bush because it`s designed to move anyway, I changed the ones on my Senator after 250k and it didn`t make an ounce of difference so thats my last port of call.
I don`t think it will be a rear damper, it doesn`t drive like one has failed so that only leaves the diff mounts an dinspection will have to wait until the weather fairs up and I have the time.

[robson]

Kevin get him working on these ideas

[chrisgixer]

Maybe won't help. But ime if tyres misbehave its in a straight line. An overly compliant tyre is usually fine in the corners, as any slop in tyre construction is taken up by side load.

[Lazydocker]

I'd best pay attention... ISTR Gayboy mentioning I needed new ones when he was playing with my rear end

[chrisgixer]

well if you let esta know where you live, that sort of thing is likely to happen

[05omegav6]

If it's not raining and you're bored on Monday... I will hopefully be making new ones

Have a bit of wiring to do first though

I have KU39s in 16" size - no problems from me.

[05omegav6]

Finally got around to tackling these

1. Old ones off...


2. Rubber burnt off, cleaned up ready to go...


3. Bolt hole filled with wax...


4. Subframe location masked off, ready to mould...


5. Finished product front...


6. ...And rear...


Not perfect, but better than what was/n't attached before. I hope

[Nick W]

That's the obvious bit done.
No you need to bolt them on the car, and see just how durable they are.

Watching this with interest.

[05omegav6]

Oh alright then

[chrisgixer]

What shaw is that material Al, do you know?

[05omegav6]

What shaw is that material Al, do you know?

75-80, but feels more like concrete

All fitted and been for a quick blat, seems ok...  haven't driven it in anger yet as ramps and tools loose in the boot, but doesn't seem overly harsh/noisy...

[chrisgixer]

Feels like concrete to the touch/holding the part in your hand...?


But ok to drive? Could void holes be drilled if too hard?

Would be interested to drive it.


Could the same goo be used to fill in the standard voids? Guessing yes.

[05omegav6]

There's alot less give, ie none, than I was expecting, but they locate the subframe to the chassis, so won't separate like the oe ones, besides the diff itself is still mounted to the subframe with the original bushes

Don't see why you could simply fill the spaces on an intact mount, but might not be that straightforward
