SLIGHT side to side is normal for a used turbo. In/out play is bad.

ok i kinda figured that but what are the things i should be looking at to see if its a good or bad turbo

also look for cracks in the housings

[seth98esT]

Cracks in the exhaust housing, specially the where the wastegate is. Look at the compressor wheel, make sure none of the fins are bent and such.

A dial indicator is a rather cheap but useful tool. It is positioned on the end of one side of the shaft, while movement is applied to the other end of the shaft. The dial will tell you the amount of end-play is present. The turbo manufacturer should be sought for the exact amount of "allowable" end-play.

And get the magnetic base for mounting the dial indicator to anything. Here is an all-in-one.
