Depending on how bad the noise is...
It's always better to fix it now instead of later. As specially if your not sure. If it was my car, I might push it, But I know what the car sounds like and have clue.
The clutch kit comes with a new pilot bearing so either way the noise should go away.
I said in another thread today, I think its easier over all to remove the engine from the tranny. When the engines out you have lots of room to work in the clutch and FW
You need the car at least 2ft off the ground to get the tranny out with ease.
