Universal replacement

Anybody know how long a universal on a drive shaft should last? It has 121000 on it I I think I feel vibration. Thanks

 

Do your u joints have gease zerks?

 

Yes. I grease them every summer

 

Does the first gen have a two peice drive shaft like the second gen? Most people have the carrier bearing go before the u joints as far as I can tell.

 

Mine have 325,000

 

I have 2 joints plus a double cardem in the center. No noises just a vibration once in a while. After doing research a u joint issue will have constant vibrations.

 

yes.

 

There are many things on these trucks that can cause a vibration. Troubleshooting a vibration involves defining when and how it occurs. Define what you are experiencing.

Is it at certain speeds or at all speeds?
Is it only under acceleration?
Is it only under deceleration?
Do you feel it in the steering wheel?
Do you feel it in the seat/floor boards?

More info about your truck may help also.

Is it all stock or is it lifted?
Stock wheels and tires or larger that stock on aftermarket wheels?

I am sure there are more things but that is a good start.

 

This isnt entirely true. They can have an array of different attitudes when going bad. Only when they are very shot will you get a constant vibration.

 

Thanks for all the imput. Had tires rotated and all is good.
