whats a normal noise for an ea falcon diff to make? i have a noise in the rear of mine which i was told was the diff but he also said it has leaf springs.....i jacked it up and spun each wheel and the passenger side one was squeeking so i took the brake calliper off, pads were good but there was a slight noise still im not sure if it would get worse with load/speed on it or not. the diff has probably about 300,000ks on it.

Also i know that only a narrow bush diff will fit, say from an ea, eb series 1, xf, xe, but is it possible to fit a later model diff?

Finally its a 5 speed so it has a 2.92 final drive, is there any problems with fitting a 2.77 from an auto into it?
thanks

a normal noise is no noise!! but after 300'000km you might hear a slight whine which is still ok, just anoying.. have you checked the oil level in the diff??
and they are coil spring not leaf spring..

you can fit a diff from eb/ed with a mix of lower bushes/ modification and use a eb2-el tailshaft..
you could even use ef/el diffs but more work is needed to either fit your brakes or modify your hand brake set up to use the ef/el brakes...

yeh thats what i was thining, the exhaust has more holes in it then swiss cheese so initally i thought it was that, but when the engine is switched off and you roll the card down a hill it has a very audiable noise, like a disk brake dragging kinda noise.

i took it to a mechanic to get it checked out and i guess all he did was take it for a drive, because he was the one who told me it had leaf springs in it.....after i asked him about the different bushes between ea and eb.

i tried to check the oil myself over the weekend but i couldnt budge the diff plug, is that normal? i cant see any sweat marks around the diff or diff seals, as in the oily marks from an oil leak.
im definietly thinking about getting a second opinion about it.

leaf spring in sedans stopped in XD if i remember correctly. i think ford utes still run leaf? or did that stop at AU?
and it could very well be "dragging" a brake pad. have you checked the braked to see if they are ceased or anythin like that?
