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. :o

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

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? :-\

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...

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

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 :y

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.

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 :y

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? :-\

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.

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.

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  :y

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.
Title: Re: Diff mounts...
Post by: 05omegav6 on 26 January 2014, 12:18:09
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 :-\

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.

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.

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.

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.

1. Old ones off...

Would be interested to drive it.


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

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 :y

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