I do a fair amount of work on my wagon and as I can't always afford to go to a garage and I have a secret connexion:
There is a lot of useful knowledge on YouTube, to be sure but there is one channel that I really like ~ Scotty Kilmer Channel.
Here's his indroduction vid:
This is his website: http://www.ScottyKilmer.com
He works on American cars but when you correlate with a Delica manual you can pretty much put it together. There is a lot of information on YouTube but I find Scotty the kind of guy I'd enjoy having a beer with. He's like the backyard DIY guy's hero. Currently I have a minor axle seal leak in my rear axle that has spilled 80/90 oil all over the backing plate. To fix this problem would normally require a shop press, which at Princess Auto starts at around $500.00. Scotty has a better idea ~ a big pipe and a lump hammer.
This guy rocks. I thought I'd share.
