Diff mounts then

They are like new. Unusually.

Australia must give much more squidgy handling cars.

During the recent colder temps, the ride has noticeably firmed up.

Driving round East Ham residential areas due to a closed m11(?) the ride was very unpleasant.

But then the roads are ridiculously appalling round there. Massive concrete speed bumps with a very harsh transition. Brick mini roundabouts you have to drive over due to parked cars.

To compensate, Tyre pressure adjustment due I think, but just in time for temps to rise again going by the forecast as Bertha clears off.

Considering re fitting oe rear donuts to get a comparison again.

I wonder at what temp poly melts? And will a microwave do the job?


Thinking about filling voids in oe rubber bushes....?

240° C

I though most folks used something like windscreen glue for filling voids - bonds nicely, stiff, comes in a tube.. rather than trying to melt old bushes in the wife's microwave

Tried sikoflex. Didn't bond at all. Guessing some sort f release agent on the rubber from moulding.

There's a lot of long straight roads in Australia, notably the '90 mile straight' on the Nullarbor Plain!

Also, the sikoflex I used, whatever it was there's a few, was by no means firm when set. So pointless ultimately.

You turned the top pads over

I did?

You did

Can't remember that. Although I've packed mine out with the oe rubber pad as well. Just in case the slightly loose poly pad was having an effect. It wasn't, and it's now transmitting some noise.

Point is its packed together as tight as a nuns chuf, but still loose by feel, and looser still at the indicated 27c on the CID when booting it out of a round about.

(By loose I mean a bit more movement than normal. Still not as much as oe in a turn. But more than oe re tramlining (road affecting track of the rear end)

Looks like you found the answer to this today then...

Yes poorly fitted by some idiot . Top pad on rear drivers donut not seated correctly.


However the temperature does affect them.

I suspect that the original rubber components are similarly affected by temperature, therefore any improvement made by fitting poly would apply equally in any given climate

No I don't agree there. Rubber bushes are not affected by temp when it comes to driver feel.

Variations in ride hardness is something I noticed before rear donuts where fitted, but with poly fronts. It was defo ambient temp related but I couldn't work out what component was affected. Tyres? Suspension? it was like taking 5-7 psi out of the tyres re ride feel. But as tyre would loose stability at those pressures it couldn't if been those. Suspension.... Feel a bit thick now I've worked it out, although time will confirm further as temps are due to go up, then winter approaching.

Can't explain why but this minor fault has helped confirm it, to me at least.

The ideal seems to be between 17c and 23-4c. Harsher below. Softer above.


...but as said, will confirm later, just to be sure.
