Right…. I absolutely mullered a couple of splines on the drop arm shaft.
My engineering practices ran out of steam within the 2 hour attempt of removing it 
The threads are fine I just got a “little” carried away with the grinder So I’m assuming if I just let it cold weld on like they do we should be sound…. Or am I  - and have to get a replacement box

Fair say - I’ll keep a look out for some recon or 2nd hand box’s then

Can you put a pic of the damage?
If not deep cut, I wouldn’t be overly concerned, I also assume the cut isn’t across the shaft but along it. |

Yup, a pic will help assess the damage.

Welp…. I’ve gone and replaced the steering box
And now I’m facing the joys of a couple of more issues Bleeding it is a
And I don’t know if this is caused by air in the system but I have a notching feeling going from RH down then passed centre…. It improved when I began bleeding but is still there so I’ll bleed it again after a few days worth of driving and then we shall see If u guys want a laugh I’ll show u the state of the spline next time I’m at the unit

I don’t know what “adwest” is. But, it’s a standard reconditioned box from “the steering specialist” on eBay 4.0 V8 Defender 90

Adwest was the original manufacturer of all Defender steering boxes.
Time was when you had two choices for a replacement box: an Adwest box or a defective box. Times have however changed, and Adwest boxes are harder to get. Defective boxes sadly are not. |

And there was the Gemmer box, distinguishable by the 6 bolts.
On the bleeding issue, a full right lock should remove air and oil from the top side of the actuator(only way to bleed that part). A full left would pressurize the top side (would be front end if the box) of the actuator. Generally a few full locks left/right should expel most air, and then only need to bleed whats on top of the box through the bleeding nipple. Just ensure that the oil is not foaming. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |

I recommend doing the full left/right etc then switching off for maybe half an hour before removing reservoir cap and then opening box bleed nipple with engine still off and allowing any air out of the nipple just under the force of gravity.
When trying to bleed these boxes in a hurry with the engine running it all gets a bit frothy and you don't get anywhere fast. Better to take your time and let natural settlement do most of the work for you. I don't remember ever really struggling to get it bled, but then I do do the initial fill and bleed by gravity with the engine off which seems to give good results. Maybe this leaves much less air in the pump and box to get whisked into the oil when the engine is started? |

You make a good point about the fluid frothing- I can certainly hear it when I’m turning the wheel as I’m attempting to bleed it.
I’ll give this a go today as I have a few smaller jobs I can do in the meantime on the car. 4.0 V8 Defender 90

After I let the engine rest for 30 do I open both the reservoir cap and undo the nipple? Or do I keep the red closed and just into the nipple 4.0 V8 Defender 90 My Instagram |
