Half Shaft ?

[FULLPWR]

Took em to the driveshaft shop.

He said "sometimes that cardboard can swell and shrink depending on the enviroment there in and after looking over them really good he suggested not to pay him $75 bucks each to balance them, unless I felt like throwing money away, because they would be just fine like they are. He said its very rare for a aluminum half shaft to become out of balance without some brut force, irregular damage (wreck), heavy hp, and on the other hand steel shafts are not as flexible and tend to deform under extreme torque pressures." He said if they were steel he would recommend a balance. but mine look good.

I think I'm gonna stick em back in and see what happens.
I never heard any noise similiar to the cardboard noise when driving it.
