Just finished the installation of my aluminum driveshaft. It went very well thanks to the tips from PBGas on an earlier post. Did a short road test. It seemed to wind up a little quicker. I also removed the mooseballs. What a hunk of junk.

We haven' t installed the shaft in my son's Bullitt yet (too damned cold here) but I recall an earlier post where someone said the "moose balls" were mainly for the original setup. Harmonic balancers are "tuned" to a specific combination or parts and therefore, won't help with the aluminum driveshaft.
Someone please correct me if I'm wrong.

I think you are correct about the mooseballs are for the original setup. I did not get any noise or vibration when I road tested it. In fact it was smooth and quiet. I say take em off and save the weight.

same for me, after the AL drive shaft install I noticed a LOT of noise reduction. Few months later I removed the weight on the differential and did not notice any difference in noise during different speeds and RPMS.

Yup..... no one likes touching the Moose Balls. Too rusty!

Seriously...I haven't even removed mine yet! I will take them off one of these weekends. As previously posted...it is setup for use with the steel shaft. Once you remove that shaft, then basically you change all of the dynamics.

Would someone please tell me what part# you ordered. I went to the site that was shown however, only lists up to a 98 model year.
Thanx BULLITT837
