depends on how much shaft play your talkin here. I have a little shaft play in mine too(jdm 3rd gen turbo) but thats because its sitting for a YEAR NOW and has no oil in it. Your probably better off having someone who can tell you if the seals are bad or the bearings and such. It is more than worth the trouble, it is a far better turbo all around the ct26 you have now and the ceramic is a nice touch. Rebuild kits are not that expensive for just some bearings and such , and possibly not that hard if you dont mind the experiment and such.
fwiw
