A screeching noise has manifested itself from the front end. Process of elimination fault finding has narrowed it down to either the speedo gearbox or a wheel bearing.
Bearings tend to moan before they screech; the wheel turns freely by hand with no noise, lateral play or other signs of distress, so I’m putting my money on the gearbox.
No problem. I have a serviceable spare.
The wheel is out.
Now to the issue. I can’t shift the spindle nuts. Even with one side clamped in the vice with metal blocks in the spanner grooves, and a ring spanner plus extension bar on the other side isn’t shifting it.
I suspect that they’ve corroded together.
Any ideas regarding undoing them, short of biting the bullet and hacksawing through the spindle, putting it back together with replacement parts?
