Is This Noise The Throw Out Bearing?

I like your first answer the best Madmaxx because there's no work involved. Remind me to have it checked in 97,500 miles.

Madmaxx lives here in Houston where its 95* and 50* humidity today. All standard answers this time of year involve "No labor required at this time."

I wish it were that cool!!!!!!!!! Try 99 and 50% humidity for the last 28 days, we usually do not see this until late July early August. June is usually one of our wettest months so I planted sod about mid may, not a drop of rain since then. If you have an outdoor activitiy and want to prevent rain I will sell you a piece of my sod and I guarantee you it will not rain LOL!!!

As far as the noises, I have chased them all in the past with no improvement so I would hope others would learn from my mistakes.

Our cars even dailey drivers for all practical purposes see no wear. I work in a plant environment where equipment runs at 3600 rpm, 24 hours a day, 7 days a week. In fact our mean time between failure on pumps is 4.4 years. That is equivalent to 1,927,200 miles assuming 50 mph. In reality it is much worse if the pump has a 3.375" shaft turning at 3600 rpm, it is 1734 miles per day, or 632,959 miles per year is what the linear distance the shaft turns. We will pick up a bearing vibration and change it at the next turnaround, usually 6 months down the road, so even when we think the bearing is bad it will travel another 312,000 miles.

I really do not think the throw out bearing will wear out if it is in constant contact with the clutch fingers at all times.

The throw-out bearing rides on a set of rollers. I just replaced mine, and it spun freely, but it was somewhat deformed: that is, both pieces were no longer concentric about a common centerline. I'll bet your clutch slave rod just needs to be adjusted to just break contact with the fingers. The fact that you said it goes away after a second or two sounds like a lag time in the hydraulics allowing it to rub momentarly. Is there a spring on the slave cylinder piston?

I'm going to get the car up on jackstands for the first time this week and I'll report back. No harm if I leave the car up on stands for a few days?

No problem...

Problem? Mine lived on jack stands, until recently.
