I am wondering if the release bearing clips and the release lever cotton clips should be replaced when replacing clutch and release bearing. Does anyone know if they break off and cause trouble?

 

Here is one thread

Thanks

but replace them if they are available.

They're cheap to buy, go ahead and replace them.

I did replace them. I would recommend buying while buying clutch kit. Pin is 1.64 at 1st subaru parts. 4.11 at dealership...12 bucks for release lever clip!
