Land Rover Repair: Rear diff problem, land rover defender 90, land rover defender

Question
I have got a 1996 land rover defender 90 300tdi.
this morning when i went around a slight corner i just heard 2 loud knocking noises from the rear diff. when i continued driving i could hear a very loud diff hum noise when the vehicle is traveling in neautral gear or clutch pedal pressed in, which was all of a sudden new after the loud bang on my diff.

Answer
Hi Zander,

ouch!  Was there oil in the diff?  Replace it and see if you have metal filings.  Take a magnet and swirl it around the pan to collect metal - if you find it, you've got some problems that requre attention. Probably a new diff.

How about the transfer gearbox?  Does it also have fluid?  Do the same as the diff and replace the fluid (while looking for filings).  I had my TG go like you describe.  Loud bang (seized up temporarily) then rough sounds.  

Best of luck,

JohnMc
