I have just got Subaru hupcaps for my 97 Outback Sport.   I know this sounds dumb . I cant get them to stay on the wheels. The say to rotate on put on. How do they stay on. They look the have clip to lock into something, but the wheels do not have anything that would to keep them secure

 

 

Line up the valve stem with the valve stem indent on the hub cap, then just press it onto the wheel. I usually take a rubber mallet and tap them into place. There's a metal hoop in the hubcap that seats on the inside of the steel rim. If you don't have stock steel rims or they aren't stock hubcaps maybe they just aren't compatible. A picture would help if you still can't get it.

 

 

Or do you mean the little center caps in the middle of an alloy rim? In that case, there are a few different ones that look the same..

Chris, there's a full subaru wheel cover that sets into ppace, then you rotate it, to lock it into place. There are actually little plastic locks that are attached to the wheels, and the wheel covers twist into them. Not for sure that's what he's talking about. It wasn't the best design though, and it's common for them to not stay on.
