Bad bad news

[white71chevy]

I need to no what's wrong with my truck. its a 71 chevy with a 305 in it and I'm pretty soon it is the original tranny. So here's what happened I was driving my truck and at 60 it started making this really loud squealy nosie. So I pulled over as soon as I could I got out looked at everything I thought it was the pully. The pully looked fine as did everything else. So I got in it and put it in gear and it was like the tranny didn't want to pull the truck into a roll so I gave it a bit more gas and it moved. After it started moving the tranny did fine no nosies or drag I only went like 20 tho. Idk what's wrong with it is the tranny going out? Can it be saved? Or do I have to buy a new one? Also the truck was sitting for 5 years I got it running a few months ago and I drive it as much as possable it has made this nosie a few times but I thought it was just the pully. Its running great has no problems with all trips or anything its just that nosie and now the tranny. I need to know what's wrong I have been working all summer to drive this truck my senior year it starts in 2 weeks. Sorry for long post I'm just really weird my truck is messed up I love this truck its my baby lol plz help.

4 speed ,3 speed or auto??

[sjarrett71]

Are the brakes locking up on it? Was you only going 20 because you wanted to or is that all your truck would do?

[white71chevy]

Its auto sorry.

[white71chevy]

I don't know about the brakes. I was thinking it was the tranny but it could be the breaks now that I think about it how do I check to c if the breaks are locked up. I was going 20 cuz I wanted to I was worried it would hurt it more and it could of done more but I didn't want to push it.

you can learn a lot about your AT by checking the fluid. Check the color and smell it.

[white71chevy]

Its the same color as the stuff I put in it idk aboutt smell tho

Check the carrier bearing on the drive shaft

[oldblue1968chevy]

Good luck man! Take the driveshaft off maybe and pull it around? See if it does it?

What's the carrier bearing? Where's it located at and how do I check it

Crawl under the truck and start at the transmission. Look about half way don the driveshaft. It will be supported in a frame crossmember and turn in a bearing. This is the carrier bearing. They can dry up, get hot and go bad. If you grab the driveshaft and can move it around, you KNOW you need a new bearing. If it is still tight, you might still need a new bearing......the big thing is finding out where the noise is coming from.

if its not belt/pulley related...

does this truck have an a/c compressor? if so...the clutch may be squealing?

or...could it be a squealer on the front disc brakes? If it starts squealing, can you put light pressure on the brakes and make the noise stop?

[white71chevy]

Ok thanks ill look at it tommrow and I think it might be the pully when the truck is in park and I gas it. It will make the same nosie.

I had a similar problem and it turned out one of my belts was old and not tight enough. If I remember right it was the power steering belt.

Here's a trick for ruling out or temporarily quieting a squealing fan belt....
Get a can of Coca-Cola, Pepsi, DrPepper...what ever kind of sugared soda you have handy, and with the engine OFF douse the belts and pulleys with the soda. Start it up and the sticky sugar will help the belts get a grip on the pulleys. Now you can listen to check and see if there is something else making the noise.

Get a LONNNNNNG screwdriver...think more than a foot and a half...and use it like a stethescope to listen to the alternator, water pump and power steering pump. You could have a bad bearing in one of the three.

You indicate that when you restarted it and attempted to go it didn't seem to want to roll. If you had to give it more gas than usual to get it moving and it was squealing when you were driving it, I would first start by checking to see if brakes are hung up in the rear. Did you recently try out your emergency brake?

i have used the e-brake before but not that day the e-brake hasnt given me problems before. How do i check to see if the brakes are hung up. Also the carrier bearing is out i think i can move it by hand and it moves a whole whole lot!

ok i looked at the carrier bearing and i can move it all over the place. so do i get a new one of those and if so will it fix the problem. also will it be hard to do it myself (with my limted know how on this lol) or should i take it somewhere to get it fixed. if so what would be a good price for it to be done. sorry about all the questions.

If you can rev the engine with it in park and it makes the squeal then it's not brakes, carrier bearing, etc. Try loosening the alternator belt and crank it to see if it still does it. No? Then the ps belt. That will eliminate those 2.
Is it maybe a whine instead of a squeal? Could be a torque convert or front pump failing in the tranny or just the tranny filter stopped up starving the pump of fluid. More testing is needed to narrow it down.

Ding, Ding, Ding! Winner! If it makes the same noise in neutral when you gas it and the truck has been sitting for five years. I would think that the belts are making the noise and would replace them all. When the belts are off check the play on the water pump, if you can wiggle the fan the pump is probably bad. Also check that everything spins freely.

If the carrier bering is that loose you need to replace it too. It may or may not make noise. If you don't know how to or have access to the tools necessary to do that job you may want to have a reputable shop do it. There is nothing that will shorten the life of a bearing faster than a guy with a hammer that does not know were to hit it.

Since you are a novice at this, it might be a good idea to seek help from someone that would be willing to let you learn while fixing up your truck.

These trucks are simple, easy to work on for the most part, and it's rewarding to see the fruits of your labor. I would however caution you again to seek help in the form of somebody that knows what they are doing. Remember this is a project that you are going to be driving around in and carrying your friends in at speed.

Good luck, you will have the coolest ride in the whole school.

Just my .02 worth.

the carrier bearing is what connects a 2 peice drive shaft it is almost directly under the joint between the cab and bed on my truck I assume yours is the same

[white71chevy]

Thanks guys for all the help. I fixed the problem and I think I no what's causing the nosie.
