Mystery Squeek - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My truck developed a new squeek this weekend

My new sqeek happens when I hit the gas while driving. If I put the
clutch in and hit the gas it does not squeek. Its squeeks faster as I
go faster. Does this mean it is in the drive train?

It sounds like its coming from the front right, I have looked around
over and under the truck looking for the source but so far no luck. Any
ideas? I hope its not my tranny or rear....

Either the clutch throw out bearing or harmonic balancer outer ring slipping back off center and rubbing timming cover (pushing clutch in pushes crank forward).

kinda sounds like u joint to me

cdowns · 08-29-2005, 11:28 AM

check upper shock mounts

farside847 · 08-29-2005, 11:36 AM

cdowns: I thought of that too, so I went under and checked all the shocks and they look ok. Also it does not squeek when I am moving at 30mph and the truck in neutral.

jhow66 and tnblazerk5: how would I check the u-joints, throwout bearing, and ballancer to rule them out?

Also I forgot to mention, this squeek comes and goes. I drove 3/4 of the way to work today with no noise at all, then it started to squeek again for a few minutes, then went away again.

thanks guys!

lol get under the truck and try to move the drive shaft up and down where it meets the u joint

i had one doing what you have said and took me a while to find it. i could coast and it wouldnt make a noise and give it gas and it would make a noise i even got under there and checked the u joints by hand (tryed to move the drive shaft up and down near the joint they felt tight so i tought they were good to go but i was wrong one of them was dry of grease and was sqeeking it finlly gave uo and broke lol thats how i found it

I second the U-Joint

Yeah, might as well buy a u-joint, you're gonna need it pretty quick.

Sillyoldman · 08-30-2005, 11:14 AM

Throw out bearing.

Well, made it in to work again today (I drive about 20 miles each way).

Turned off the radio to listen and the squeaking is quieter, but it is now accompanied by some knocking and vibration. It starts when I start from a stand still in 1st, then goes away. I shift into 2nd and it comes back then goes away, then 3rd seems fine. If Im lighter on the gas pedal it doesnt seem to happen as much.

Could I hurt something else by continuing to drive it? I wont really have a chance to work on anything till this weekend.... I could probably open up my trusty manual and learn how to replace a u-joint.

if it is the front u joint and you keep driving it and it breaks while your driveing and digs into the pavement it will not a good thing and the truck really wont like it it(it acts like a pole voult<sp?) its the rear u joint and it breaks it will just fal ot the ground and drag and the truck wont go anywhere inless you got a 1 peice drive shaft then it just falls all the way to the ground and rolls around in the road till a the car behide ya hits it
