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

Have summat more permanent on the way Suspect my separated one is past sticking back together

[chrisgixer]

With a fair sized dollop of body roll for good measure

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

Airfield you say...?

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?

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.

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.

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

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.

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.

Sounds like a solution

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.
