Ark & Shalyn: I look at VW stuff just the other way around. Of course, for me it is (was) a matter of familiarity. Every time I work on some Yank tank or Jap scrap, things are done differently and I never seem to be able to "settle in" (I won't even bring up Brit BS in this discussion!!!).
The secret of working on VWs (and probably everything else) is preparation, patience and knowing a few trade secrets. Before you start a new job, read....STUDY....the Bentley for your car, and spend some time looking at the car. It may not give you the shortcuts, but most of us are not on the clock, so just follow the steps and it will come apart - and go back together. TAKE YOUR TIME...unless you are indeed in a flat rate shop - and even way back in those days, I would rather get it right and do it only once. Oh, yeah....CLEAN the bloody thing thoroughly. Again, not on the clock, and the quality of the job will be much better because you won't be pixxed off and the parts won't be filthy going in.
The right tools are mandatory. A fastener is a fastener, but a wrench is NOT "just" a wrench. If you can't get an axle nut off, you are probably using a 1/2" breaker bar. I use a 3/4" impact, or in the field a 3/4" breaker bar. If you ever had to get axle nuts off of old, rusty Type II reduction boxes, you would understand why. Critical fasteners (CV splines, etc.) need decent quality tools - or you will strip stuff. ALWAYS grab a 6 point socket to break hex nuts loose, not 12.
There are trade secrets in how do do some things as well. When I hear of people looking for pullers for tie rod ends and other tapers, I kind of chuckle. Yes, I have a mess of them, but they seldom need to be used. It takes some practice, but the way it is done on the floor is to loosen the nut a bit, then use a fairly big (3 lb) ball peen as an anvil and strke the opposite side of the steering arm with a smaller (2 lb) ball peen at right angles to the taper centerline. Usuall in one or two hits, the taper will pop right out. Not love taps, but pretty agressive stikes are needed.
Don't use mickey mouse press tools (such as spring compressors). Get something designed for the job (or made if you know how) that is at least twice as good as you think you need. Not only will the job go easily, but you might live to tell the tales. There is a LOT of energy stored in a suspension spring, so give it the respect it deserves.
IMHO there are three levels of performing any task: workmanship, tradesmanship and craftsmanship. Chill out, think ahead, get the right mindset and enjoy the craft.
