That $50 Amazon tool is a game changer. I stubbornly struggled and eventually succeeded with the standard C-clamp style bearing press tools and some inventiveness, on my 2001 3.0i with springs, soon after first getting the car a few years ago. Never again, BTW.

I was pretty cautious about replacing parts that did not need it. When I did replace, it was with Lemfoerder. Some of my parts - e.g., guide links (rear axle front upper control arms), sway bar links, rear shocks - are so easy to replace if and when they ever fail (not yet, at 190k miles) that I did not see a reason to do those ones "while I was in there."

But others - e.g., integral links, opposite side control arm when one was too loose - did make sense to do. So that's what I did. In my case, the ball joints were the real problem. Replacing those alone would probably have been sufficient at about 170k miles. Integral links were out, buried deep, cheap, so those got replaced. One of my rear upper control arms was loose, so I replaced those on both sides.

Although the rear shocks will come off and it's of course easy to put new ones on at that point, replacing those at a later time just requires jacking up the car, taking off the wheel, and two bolts.

In my case, I found the intermittent squeaking I had been hearing was due to the rubber seat things at the top and bottom of the springs. I just removed and cleaned those carefully, re-greased, and they have been silent ever since.

Depending on your mileage and condition, I would be concerned that you might actually be taking a step back by replacing a well-functioning original part with a Meyle.
