I have been told i have a small leak on my near side drive shaft seal. How often should i check to see the level of the oil in the gearbox? I dont want to let it run dry, but also dont want to check it more than i need. What are the symptoms of a gearbox with low oil, and what signs are there if a gearbox is on its way out?
Cheers, its an area i know nothing about, so any help appreciated.
