I have an 03 blazer there is a lot of noise coming from the transfer case, I think the chain may need to be changed, or so maybe a bearing in the transfer case, where is the best place to get parts for this I am looking for a rebuild kit preferably.

Has anyone on here rebuilt their transfer case?

Thanks for you help
James

 

Here ya go:
NP233 Parts - Drivetrain.com

I have gone through the NP231, but from a Dodge. It is quite similar inside to the NP233. I recommend you get a manual.
