Driveshaft Allignment question

[tim21391]

i just wire wheeled, sanded, and prepped my frame and shot some surface rust converter primer on my frame then shot it with some black undercoating.. i sprayed the top of my driveshaft with the udnercoating... people told me that if i do the whole thing it will throw my driveshaft off since i guess it has to be weighted right....i dont think it really matters does it.... should i be fine if i continue to paint up my drive shaft??

I would remove the undercoating, and paint it.
Remember, that thing will rev to what ever RPM the engine is going when you are on the freeway.... 3000+ RPM is not uncommon on the freeway in these. if you have an overdrive, then it becomes even more important since it'll spin faster than the crank.

I agree with Lonhorn Man.

I had a driveshaft balanced once and I was told to never put anything more than a coat of paint on it. They're relatively easy to remove and repaint if necessary.

oh ok because i have everything painted on the rear half of my frame and i dont want the driveshaft to look nasty lookin....so your thinkin just normal can of black paint should be fine?? any primer??

[Longhorn Man]

treat it like you would any other piece of steel that you are painting. Remove rust, degrease, sand, prime, sand, paint, clear if you feel the need... then call it good.

i ended up painting my exhaust with high temp paint and i had some left over..so i painted my driveshaft with exhaust paint haha... it gives it a cool look... exhaust and driveshaft is flat black with my frame..shocks..and coils are all undercoated..

IMO, it a driveshaft doesn't need anything more than paint. Has anyone ever seen one rusted in two?

[tim21391]

no but i was saying... didnt want to leave it not painted while everything else is painted black..
