Grinding noise question

Every once and awhile when I start my jeep with the clutch pushed in I get a loud spinning/grinding noise that goes away when I let the clutch out or after about 5 seconds. Is this my throwout bearing? When I decide to drop the trans and take a look what parts should I change for the simple fact that I already have the trans out of the jeep so I not going back in 2 years later? Thanks for the help everyone!!!

I would bet this is your pilot bushing actually... could be your throwout bearing.. but really sounds like the pilot bushing.

When you drop the trans.. I, personally, would take off the clutch and flywheel.. have the flywheel machined, get a new clutch (I used LUK), get new pilot bushing, get new throwout bearing.

Couldn't hurt to drain the trans.. pop the cover and look around.

That should make you good to go man!

I tend to agree with the previous post. It could be either the throwout bearing or the pilot bearing/bushing.

If it goes away after you let the clutch out or after about 5 seconds with the clutch pedal depressed, I'd tend to look at the pilot bearing/bushing...

because, if it was a throwout bearing problem, it normally would keep doing it as long as the clutch pedal was depressed.
