Crankshaft Pulley 5.8 vs. 5.0
 

I have a slight problem, my crankshaft pulley is wobbling. I've checked the bolts, and the harmonic balancer, all is fine. I've been looking for a pulley to replace it with, and haven't had much luck finding a stock one. Well, not had any luck finding a stock one for less than a underdrive set.

Here is my question- I've decided to put a set of underdrive pulleys on, and have found there are not very many sets for the 5.8l truck. Is the 5.0 crankshaft pulley the same size of the 5.8? And, will an underdrive set for a 5.0 work on a 5.8? Has anyone done this?

short answer yes, you can use the 5.0 pulleys , however underdrives are not usually a good idea on trucks , due to charging and cooling needs , especially if you tow!

Thanks for the input.
I have an e-fan and an overdrive pulley on the alt. Probally what causes it to go out every 2 years or so.

anybody know where I can get just a crank pulley?
