How do I know when I need a new clutch?

[kabel]

you'll know when it's really going. Like nefarious said, it will slip more and more until it will no longer grab. You should have enough warning.

After getting an alignment last year the tech wrote the same thing, "clutch needs replacement soon" I think our clutches just have a longer throw, because mine still grabs just fine thought it is very near the top of the peddle travel.
