Welcome Aboard!:welcome:

I am not positive, but my guess is they are referring to the two different axles available on the Cruze. The Z-Link and the regular (not sure what the name is).

Don't forget to introduce yourself and your Cruze here.

 

Surely someone's replaced their wheel bearings...

 

It's not a commonly replaced item. And used to require a press.

There's a 72 year old mechanic on here that could tell you for sure on the press thing.

 

My best educated guess is the 15" wheel option has drum in the rear, the 16" option has disc. You state your car came with 17" wheels? or did someone put 17" on it?
Do you have drum or disc in the rear?

Edit:

 

Came with the factory 225/50/17s when I bought it

 

Well, how about this.
Can you post your RPO codes? You'll probably find them in your glove box, affixed to the door. If not there, maybe affixed to the underside of the spare tire cover/lid.

 

The only differences I can find are for gasoline version, 105mm lug bolt circle, and diesel version, 115mm lug bolt circle.

Was there ever such a thing as 15" wheels on a U.S. Cruze?

BTW, no press required.....you are replacing the entire hub and stub assembly.

 

I have seen 30 spline and 33 spline. I also have to replace mine with 17" rims

 

I have the same car and did the same swap. I went through GM. You can use the dealer or the GM parts direct website, enter your VIN and the parts will pop up. I didn’t have much luck on the aftermarket front either.

no, they are simple bolt ups. Bolts are TTY so try and find new ones if you want (good luck), replace with hardware store bolts or reuse them (not particularly recommended, but I did)
