Question Strange Diff Noises!!!!!

My car has developed a stanged diff noise, when i take of slow it moans, then goes away! And tonight it started making a strange small bang when i select reverse and only reverse!!!! I have heard a taxi diff that was stuffed and it was noisey while driving but mine only makes these noises while taking off and a little clunk when i put it in reverse!

Its a standard diff in an EL with 73000kms! And the car dosent get trashed really, only sometimes i give it the boot!

If the diff is dead i dont get it! Why??? I am gonna change the gearbox and diff oils soon, hopefully this will fix it!

Any oil you guys can recomend appart from the stuff Ford recomends in the owners manual????

I use the Nulon G70 in the gearbox and diff as well as teh reccomended oil. For an auto box use the G60.

My baby has done nearly 200k not a problem from the diff.

Lightbulb Where's the noise coming from

Dood, I had the same problem with my car (EB, if the name didn;t give it away)

Sounded like there was a moan from the back when you started her up and was a bit slugish off the mark, and a clunk when put it into reverse. Trouble was, I thought it'd go away, mabey just needed to blow it out a bit. N e way, The noise started to get louder and louder, I then noticed that it wasn't coming from the back n e more, but under the bonnet, turned out I had busted a ball barring in the Fan belt tentioner. The sound was soft to begin wuith and wasn't loud enough to hear it at the front until it travelled past me, louder it got, more to the front it got.

Hope that could help elliminate something

Dan

This is comming from the back, coz the clunk is comming from the diff. As i said when i am driving along and back off so the revs drop right off, then i tap the accelerator i can hear a clunk from the back, as if there is lots of free play!!

I have noticed the decline in performance, it wont rev as freely or its just me!!!
