1991 1HD-T with 560k km (350k miles) - Advice on BEB and Axle rebuild

[Didac]

I now own my father's "unbreakable piece of metal". It is a 1991 1HD-T 5 speed manual with over 560k km (350k miles).
He got it in 2005 with around 250k km.
The "maintenance" done was (2005):
- New OEM turbo
- Rebuilt diesel pump & injectors. (after this it had less power and its mileage improved significantly, around 9L/100km going ~90kmh)

Since 2005 nothing important has been done to the car since it has been running ok and mostly on highway, other than some bearings replacement.

I am planning to do the following preventative maintenance:
1.- Replace the big end bearings, as they have been the same for, at least, over 250k km
2.- Rebuild the whole front axle

I would like to know what you think or if you have any recommendations regarding these repairs

Thanks from Spain!

Congrats with your dads 80.

With 20 years and 250K of use and no mayor repairs, I would go totally over the whole truck, because there will be more that needs attention.
