When putting the diff back together i was aware that i had to do a better job of sealing the gasket as I was already I had an oil leak from the diff – based on the position of oil on the floor.
Whilst handling the cover I spotted a speck shining on it which wouldn’t wipe off. Taking a closer look I realised it was a hole with light shining through it.
Used covers on eBay were selling for about £40 so I thought I would try a repair. Many years ago I repaired a hole in my minivan gearbox with fibre glass that lasted for the years I had it …. so thought it was worth another try on the cover.
Job done and cover refitted …… fingers crossed!
