I agree with Shinsplintz. The cartridges are pre-balanced and as long as the correct torque is applied they work fine. Mellet are very reputable. I know of 2 that have been done and are totally trouble free. We will be going down the same route with my Stepsons V70R (internal oil leak on cold side oil seal).

You are better off taking the whole turbo out as you will probably find the exhaust side will be cracked. My original was and the "good condition" one I'd bought from eBay was. I rebuilt mine myself with new seals etc and new exhaust housing using the excellent guide in the articles section. That was circa 10 years ago and I've put over 40k miles on it with no issues and boosts perfectly.

If you do it yourself the main nut over the intake blades is reverse threaded and is only a small torque level. If you read the guide you'll see why I mention it.
