Default Stock turbo ?s

What is a safe amount of shaft play in a stock lb7 turbo? Mine has a sh**load and I'm pretty sure it's leaking oil. I have an opportunity to buy a stock used one with 120k miles for $150, just want to know how to check if it's in good shape and is that a fair price?

A little bit of up and down and pretty much no in and out play at all.

The one in my truck has a pretty hefty amount, like 1/8 or better up and down. Is that considered a little bit or are we talking little bit as in thousandths of an inch?

Are there any signs of the wheel hitting the housing? check if the wheel has wear and also wear marks on the housing itself

This is all going off memory, I don't have it apart to look. I just remember messing with it back in November when I had the motor apart. I was just poking around Craigslist and saw the turbo for sale and $150 seemed cheap so I figured I'd ask. I don't remember seeing any marks on the housing or wheel then but I remember I could move the turbine around enough to make it hit the housing

Don't wait for it to blow up! 150 bones could save your much more expensive intercooler.

Well, one thing leads to another.
Make sure that replacement turbo is good

Excellent. I'll probably pick it up. How much is the batmowheel and what's the benefit? I may wait and throw it in too
