Went through 3 throwout bearings in 1 month/ 2003 Dodge Ram 2500 Sign In

My throw out bearing went in my 2003 Dodge Ram 2500 manual long bed 2 wheel drive. I had it replaced by a friend and that one went in the next 200 miles. I then replaced it with another and that one went in 40 miles. Does anyone have any idea why this is happening? It is killing me financially!

Does your clutch pedal have a couple inches of free play at the top?

You don't drive with your foot resting on it do you?

Hi,

I dont leave my foot on the clutch. There is no play at the top. Someone said that if the flywheel isnt torqued correctly that it can cause the throwout bearing to go bad quick. But I have been through 2 bearings in the last few weeks.

There isn't supposed to be any contact with the throw out bearing when your foot is off the clutch but if you have no free play, something is wrong, possibly an adjustment.

Engine size? Hydraulic clutch system is going to take up the free play

What happened to the original clutch release bearing? Was a clutch job done on this?

This is a 5.7 Liter Hemi. I am pulling a 13k Lb 5th wheel across the country. I bought the truck at a dealership a year ago and they replaced the tranny with a Junk Yard tranny. almost 1 year later the throw out bearing went. 3 weeks ago myself and a friend put in a high performance clutch kit with a new throwout bearing and all. That throwout bearing went in 2 weeks. Friday night we ripped the tranny apart again and put in a new throwout bearing. None of these parts were OEM which may have been a mistake. 40 miles after putting the new bearing in it went again. Im going broke here and dont know what to do.

Could be installation error, the front bearing support is worn out causing the bearing to bind or cock, and/or the aftermarket performance clutch system may have caused a difference in tolerances that is putting too much load on the bearing which results in it overheating. I'd say go back to the OEM set up and be sure to follow the manufacture's service procedures.

? Something is all wrong IMO.

OK - Used trans when you bought it lasted a year for the record. Nothing since is lasting apparently so ask what type of failure do you find with the release bearing? Noise and a roughness when pressure applied then feel that when it's in your hands to replace it?
Not sure I understand the NO FREE PLAY thing/comment. None are supposed to "ride" on pressure plate and if it did I still can't see why it would wear out the bearing so fast - 200 miles then 40 miles!
If you did "ride" the clutch and said not I would think clutch disc itself would take the hit and wear or if it can "self ride" by lack of free play. Not certain but when motor mounts allow too much motion (said quite a load pulled) some will lose that free play during load times which is why it's there is less free play under load.


OK: It's not behaving and think somehow super high heat or perhaps wobble of trans input shaft to pilot bearing is wildly off/worn or improper fit somehow by used trans?
Release bearing really isn't doing a thing when pedal isn't pressed or shouldn't be.
Didn't see any mention of machining flywheel - if worn from slipping would think the clutch disc would show heat damage from slipping more than the bearing.
There has to be some mis-match of parts or improper installation none I can think of would cause the bearing to fail so fast without some wild bad feel right away when put back together.


1. I wouldn't have use some HP clutch and consider going back to OE
2. Measure pilot bearing I.D. and O.D. of trans input shaft. Usually a smear of grease used for those or noise possible?
3. Evidence of the high heat if so?
4. Motor and trans support mounts checked.


Has to be some improper installation or part issue IMO for this trouble so fast. May be the wrong used trans from back when causing something but can't think of how that worked for a year?


My own observations with clutch issues is usually tech allowing trans to hang on input shaft before snugging up trans or some a mess with oil fast from like a rear main seal of engine soaking friction parts badly.


Unless just inferior parts this isn't adding up too well yet to me,

I don't think that is entirely true. When you install a slave cylinder its plunger is compressed against the fork as you put it on. And if you take it back off the plunger extends due to internal spring pressure. The pressure is pushing the bearing against the pressure plate fingers.

The bearings they use today are designed to be constantly running. The hydraulic system takes up the freeplay as the clutch wears and there is slight preload put on the bearing as it is touching the pressure plate fingers. Vehicles with manual linkage and cables have adjustment you can make to adjust the freeplay that still puts the bearing into a preloaded state against the pressure plate.

Infact, sometimes chirping sounds with the clutch pedal out while the engine is running are caused by a faulty slave cylinder.

I get the concept DS with ability for no play much like disc brake pistons close and do almost to actually touch but no real force to make it fail like this? In that case the brake would nudge or back off only enough via a square "O" ring if you will torqueing ever so little and returning.


So - What makes a bearing fail? To me, overloaded, heat enough to lose its "hardened" properties. Bad to begin with in the cards too. Does or is it able to slide on input shaft? IDK - I'd think you'd notice a problem instantly if conditions harsh enough to fail so fast.
Guess I'd have to see what happened to what parts AFTER the failure. Something tells me there was something wrong back when a junkyard trans was used?


More questions than answers for this at this point, T

Without being there to see what state everything was in when the bearing was installed or to even see how the bearing failed, your guess is good as mine, Tom.

Re: Went through 3 throwout bearings in 1 month/ 2003 Dodge Ram 2500 Sign In

I'm running out of idea on this. Now some questions:


*Who is declaring this is a release bearing problem at all?
*Once said a flywheel could make one go bad? After a year??
*Once in your hands there shouldn't be any question if the bearing is bad or not and if not sure it might take another opinion on this.


What and when does this express symptoms such as just when clutch pedal pushed or other times too? If you or friend have left this trans hanging while fastening it up it just might have harmed input shaft to this trans.


All guesses that I think would be clear if this was in front of any of us.


One more - I'm really taken with a 40 mile failure like this. No joke, only see this and most with bearing that are made in China. Not blaming a place just that the reputation of their bearings wherever used lacks sadly. When duplicate real issues happen with a part when there's no other good reason choose another brand or even pay for a dealer part,


Tom
