vibration issue.

[gjp]

I have noticed that my truck makes a whining noise. Sounds like its comming from the trans while in park,N or D. When I rev to 1500 I get a vibration in the cab. i checked the flywheel runout while it was out. I cant remember what it was but the post from george blacka while back said it was ok but boarderline. There is no cover on the Converter. Is it a normal sound to hear. I tried to record it but its hard to hear it. The vibration could be from the solid mounts?? I have yet to be in a car with solids mounts but it vibrates a lot more then stock. Idleing I just hear the noise. I pulled the converter by hand to the flywheel and hand tightened the bolts then torqued the bolts. Should I recheck the flywheel and what is ok as far as measurements go. And if the flywheel is bad can it be removed while the engine and trans is in. . Thanks

Re: vibration issue.

Ive noticed a lot of vibration at low rpms or at cruiseing speed. Its the solid mounts you feel everthing now. You dont feel the vibration at higher rpms or while on the boost at all.
You will have to remove the tourqe converter to get to the flywheel bolts, I dont think theres enough room to slide the trans back, push the converter away from the flywheel and get a torque wrench up in there for the flywheel bolts. But i dont think ithe flywheel is your problem anyway.

I checked the flywheel while out with a micrometer. It was fine. I did bump it putting it in. (did all the work alone) I will check it tomorow again. The vibration is not at idle at all. Only starts around 1500 rpm. Cant realy feel it but the dash vibrates. I took it up to 4k on a little 20-50mph 8lb boost run. I did not notice it get any worse in fact it calmed down in the higher rpm. I did wha george said and sanded the flywheel hole where the nose on the TC goes. I tightened the bolts all by hand then torqued to 15lbs and then 32lbs.
Can I remove the TC bolts and idle up the truck to see if I still feel the vibration?
Also the whining sound. Kinda like a whoowhoowhoowhoo sound. Comming from inside or under the engine. Have yet to track it down. Again it could be nothing. I could just be worried for nothing but with 12k into this thing and it being my first time I am just making sure.
Also the tall rpm valve cover is real close to the brake booster. In fact its touching it. Could be vibrating the dash?? I have to do somethong about that too. Might have to take a hammer to the cover.?

Any chance your balancer is going bad? I think you usually see that in higher mileage vehicle 150k+

Re: vibration issue.

dampner is new. Vibration is comming from the trans area. check flywheel and its ok. I will just drive it till something blows up.

Re: vibration issue.

You sure it's not coming from around the transfer case area? Propshaft? I'd try pulling that and see if it goes away. Plus, 2wd burnouts are nice :lol:
