Disclamer - This thread shall function as an inspiration/guide/warning to other forum members. This thread does only show how I decided to perform this operation and I take no responsibility for others that will try to use this information on their own projects in any ways!
Then the fun begins 😊 The diff casing was opened and crown wheel removed. I could clearly see metal particles in the oil inside the diff casing, probably from the bearing on the input shaft: ![]() The input shaft seal was removed by punching a hole in its end face and put a large self tapping screw into it. The seal was then leveled out using the claw on the end of a crowbar/hammer resting against the diff casing with a piece of wood in between. The retainer nut was the accessible Rotating the input shaft without the other internals clearly confirm that its bearing(s) are worn. A �knurly� feel and sound was noticed when rotating the shaft by hand: ![]()
Removing the retainer nut was not easy. It did not break loose on the first attempts with a 0,5m long breaker bar. I was 100% sure that I placed the torque in the correct direction. (nut locked, shaft rotated clockwise). I heated up the nut using a small torch and then did a new attempt. Success!! The nut was removed and the input shaft was then removed from the casing by tapping it down with a soft headed hammer:
At this stage I decided to replace both bearings on the input shaft only and leave the bearings on the crownwheel alone. The bearings are now put on order and I have to proceed with removing the outer race for both bearings and the inner bearing on the input shaft. To be continued....

Very impressive and well done. I overhauled a Ford Escort gearbox back in the early 70's and all of the information to do it was in the Haynes (and other) manual at the time. Sadly, most people rarely attempt this sort of job nowadays and the manuals just say that it's beyond the scope of the DIY-er which puts people off even trying. 3 x FL1 2 manual + 1 auto

Can you throw up a couple of Macro shots of the pinion teeth, would be interested to see what they look like. FL2 MY10 TD4 GS traded in at 2 years

Seen a few of the nose bearings now and they all look identical. Shame it's never been nailed down as to a cause. Not to mix up threads but this is what worries me about the Haldex "dink" noise I and many others get when setting off. Land Rover blame the bearing failure on the way the Haldex applies torque from standstill and it certainly sounds and feels like there's some jolting going on. Love to know if the two things are related. Bell on the other hand say the bearing is too small, and no-one seems to really blame the oil.
