There's also chassis repair manuals in the resources section which covers everything from suspension, drive train, axles, brakes, electrical etc etc.

$500/HR. IF YOU WANT ME TO TEACH YOU
If you want to learn from your mechanic, I would expect it to take time over numerous visits to build rapport, earn trust and respect. Ask questions without bombarding them, or squeezing them for hard earned knowledge, and without preventing them from doing their work.
If guys feel you are trying to take advantage, expect a stone wall.
if they feel respected, and feel like you want them to share their knowledge and expertise, so you can understand an issue, you'll get different responses.
If you have a mechanic address a particular issue, do your best to educate yourself on this issue so you can ask intelligent questions. Intelligent questionsare are more likely to get intelligent answers.
Their knowledge is earned through years of grease and grime and busted knuckles.
At $100/hr+ shop rates, they don't want to stand around talking to a Muppet when they could be changing the oil in Karen's Kia
Same with mud members generally.
Many of us have learned by having a go, ****ing things up, scraping our knuckles, and spending way too long on the concrete floor to figure out how to repair stuff.
The above comes from decades of dealing with tradesmen and contractors of all kinds in a site management role in construction. You're expected to have knowledge of every trade, every system. Not possible without help from experts aka the guys doing the work.
Obviously, different people respond differently, but overall, show guys respect, show that you've done your best to understand what you're talking about, and show a genuine interest in learning about their field of expertise, and guys will share a lot of information. Sharing knowledge can make people feel important and valued.
Over the years, some of the most cantankerous guys I've had to to deal with have become staunch allies, and the most helpful guys on a project, because time was taken to build rapport and respect.
