    I just checked, the cost of a new shaft is going to be between 300 and 400 dollars!

That sounds to me like a shaft that connects to it is out of balance. Therefore the seals are getting worn out too soon.

    Came to the same conclusion. wondering if I change the yoke out and put a new output pilot bushing in it, if that may solve the problem?

  • Brad Brown Nov 18, 2013

    That would be the way to go unless you want to take the output shaft to a machine shop to see if the can balance it.

    I would check to see if your Drive line is balanced and also your u-joints if they have zirk fittings to grease they driveline most factory setups do not.

SOURCE: 2000 chevy silverado 4x4 rear end noise

I would think there is a problem with the tranfer case. I would check the fluid level in the rearend and address the leak.

How do I remove the bed from 2000 F250 Super Duty quad cab diesel short bed? I need to change the fuel sending unit in the fuel tank and think removing the bed may be easier than the fuel tank.


Removing the bed is in no way easier than just dropping the fuel tank, and the fuel tank was designed to easily be dropped down from the vehicle. Who ever told you that removing the bed was the easier way is certainly not an auto technician or even a mechanic.

2003 Chevy needs transfer case replaced for the 2nd time


I just had my transfer case rebuilt on my 2002 2500 silverado duramax. They told me that the spring that holds the pump inplace in the transfer case wore a hold through the case. He said this was common on these transfer cases. Chevy has not acknowledge the problem. He designed a steel plate, with flanges that holds the pump in place and will not wear a hole in the case again. And as far as the post to engage it once a month, the chain turns even when in 2WHL drive.
