Thought I'd change the front diff oil today. Easy job, three hours later!! The level plug was well seized. Tried heating it up, all to no avail, and eventually the inevitable happened and it was well and truly rounded off!
Ended up taking off the cover, clamping it up in a workmate (the workmate grip plugs have handy grooves in them, ideal for gripping the cover really well without distorting it) and then with my 15 stone holding down the workmate a large pair of stilsons finally did the job. Unfortunately the stilsons wouldn't bear in situ.
I now have to do the rear diff and a quick check seems to suggest that the level plug is similarly seized. They seem to be made of pretty poor material and the shoulders are shallow making it hard to get a good purchase.
So has anyone faced this and found a better way than my first attempt which I don't wish to repeat if I can avoid it!
And where can I get some new, hopefully better level plugs.
