In one word, No.
It is not easy. It is time consuming and requires a few special tools. If you're used to wrenching on cars, it's just another big job. If you're new to it, it's a fairly big undertaking.

Do yourself a favor and DO NOT replace the balancer with another GM balancer. Buy a Dayco PB1117N for about $75 and a Genuine GM bolt for $10. Labor should run you about $500-$600. I just had mine done a few months ago. I also replaced my water pump and both belts while it was apart. Don't forget to buy the seal that's behind the balancer (Timken 100470 $20) Cheers!

According to my go-to-mechanic, if it is wobbling, it is not if, but when it will fail and do damage. Mine had a small wobble at 42K so I had it done with a ATI this week and picking car up tomorrow.

I just had this done last week, like you it was more than I wanted to dig into in the garage. I had a local shop handle it, total was about $800 and change to get it done. Well worth it. And yes, a wobble means it has ALREADY failed, just not catastrophically yet. Get it done very soon.

I used some white nail polish on mine and put a few lines across the balancer. That was several years ago, and the lines have not moved.
Mine does wobble, but it has since I got the car. It hasn’t gotten any worse, so I make it a point to keep an eye on it.

Look, you've got 2 heavy steel parts joined by some vulcanized rubber. Over time, it's gonna fail, that's life. The reason they fail is the amount of force applied when each cylinder fires and causes a massive amount of torque that the damper has to absorb. Now, if you're driving some 160hp 4cyl shitbox, no, that balancer doesn't have to do do lot so it's unlikely to fail. But on an engine where torque numbers are where these ls engines are, yes, the balancer is a wear component and it'll fail. Suck it up and replace it.
Here's the cliffs: Add more HP, more **** breaks. It's the price you pay.
