I went out for an adventure today after recently fixing my crazy oil leak.

I went for a mud plug and ended up hearing a decent thud and my 4wd gone... Looking under to find that my uni had blown out and cracked the gearbox.

And yes... It is a nice crack. But the dent is better.

I was coming out of a hole. Front wheels got grip after spinning thru the mud with the loud pedal to the floor.

Apparently the above is what the end result is.

the front uj are rubbish on isuzu, if you replace them get the greasable ones and ALWAYS grease them, the above is the result of a worn uj, also that one never gets greased as its right by the gearbox x member

The telescopic bit was greased. Will new ones from bnt be greasable?

Stepfathers mu did the same thing, same situation you've described, blew uj and shredded the flange which punched a hole in the side of the gearbox. To fix it he drained the box, cleaned up all round the hole really well and sealed it up with knead-it. Works brilliantly, no harm done as long as you check it every now and again and didnt drive with low oil :-)

There are some repairs that can work really well that will never be on the preferred method list.

And the above is one of them. I have done similar with metal epoxy on a rwd conversion I did. I don't think I would be comfortable doing either on my truck... Knowing how remote I go and how rough I am.

I've got a guy tee'd up to tig it once I have the box out and split

If its just punched a hole in an alloy casing it could easily be ok. If however the hole affected a structural part of the box then the gears could now be miss aligned and very soon there will be another hole in it Bashed from the inside.
Ive had that once in a Vauxhall viva. Dont drop the clutch in reverse when its got one wheel stuck on a wall. It belonged to a flatmate many decades ago and I had borrowed it. Cost me $40 for a new gearbox and 2 hours lieing on a gravel driveway changing it working by an old 40w bulb type work light.It was also raining a little. Vauxhall Viva gearboxes are lighter than Isuzu diff heads by a large margin

I'm hoping its alright. I did drive it a good few hundred meters to the road. Sometimes its easier to drive it out than get towed.

The Viva was driven home as well despite all the oil haveing followed a gear tooth out of the box. It wouldnt stay in reverse though.
Good luck. If bogging up the hole works its a cheap easy fix and there isnt much to lose. If you take it out to weld it up you get the chance of checking out the inside at the same time and if its dodgy just getting another box.

As per the Original Posters question several replies above, the new universals from BNT will be greaseable.
The ones they used to sell had the grease nipple going into the centre of the cross.
The new ones (a different brand) have the grese nipple on one of the bearing caps.
The original Isuzu universals on the front driveshaft don't generally have a grease nipple on them, just one on the spline.

It looks worse in the photo that it actually is. Which is ideal for me. I have gone and got a BNT replacement. It'll be on the road tonight all going well.
