Should the chain be riding up the teeth where those wear marks are? I didn't have my Trailblazer long enough to know a lot about chain drives.

Lol. I dont know anything about the chain

I've been reading some stuff online about chains, and according to the technical diagrams I saw, chains ride up higher on the teeth when they're moving faster.

Interesting

And yes, it did rain. And yes, when it stopped, I did forget to look at mine. Shame I have to put a note in my pocket. :o |
So do you think the whoop whoop noise is coming from a bar bearing?
|
Went back and took a closer look at the chain in one of the pics. It's missing orings, so add a new chain to the list. I'd also add new sprockets. If you need a new axle housing, you'll want new bearings as well. The good news is, that stuff needs to come off to remove the axle anyway.

Great. Sounds costly
|
Not my sale, so I can't guarantee the shape it's in, but here's an axle housing for $50. It is the same part for 1999 and 2003. Bearings were about $15. Been a while since I bought sprockets and chains, but I'd bet you can come out around $150 for all.

The reason I asked about the wear spots on the sprocket is that one of the spaces between the teeth looks out of round, but it could just be the picture. Even if the rear sprocket looked great I would take a really close look at the front sprocket. It spins a lot faster than the rear sprocket, and even though it's (most likely) heat treated steel it could have more wear on it. If the sprockets are starting to wear out you won't be doing your new chain any favors by leaving them on there.
