One Piece Driveshaft Question

[hOngsterr]

I was wondering if this is a common thing for this upgrade.

I just bought a new One Piece Steel DS made by DSS,
Simple installation, 4 bolts and its on, my question is,

The guys that have done/experienced one, does the DS whine a bit more and is louder, and gives a bit of a vibration when driven?

I've searched other forums and I just want to make sure I've installed it correctly and if thats normal for the one piece.

Thanks

I have a Shaftmasters alum. It's resonates louder starting at 5500 rpm upward. At normal street rpm you shouldn't feel any difference.

Vibration should be coming mostly from the engine (KA). If it feels like driveshaft vibration that's not right.

I get a little vibration as well on my DSS aluminum...but I also haven't matched it yet.

Unbolt and rotate the driveshaft 1/4 (90 degress) at a time and rebolt and drive until you get the least (or hopefully none) vibration...you are basically matching the driveshaft to the differential. The same reason why if you remove a stock driveshaft and put it back in wrong you can get vibration...they are balanced and matched to the differential.

my noise and vibration comes from the drive shaft itself, i asked Zilvia about the same issue, and it just needs to get rebalanced, so now Im looking around to get it rebalanced.

when it gets gnarly is when it hits 4k+ feels like Im at high rpm, and Im sitting on a massage chair.

i just got the shaft from DSS because it was the most discussed brand.
mistake i guess, live and learn.

Thanks guys

local shops can balance a driveshaft pretty easily and it's not much money.

check to make sure you got the thing bolted up to the diff properly.. one of my diffs has a tiny ding on the front flange and it's hard to get the DS to mate up to it nice and flush. If you don't get the bolts tight and the flange properly seated, you'll have tons of vibes. I just need to take the time to file the thing smooth in my case.

also might get you a helper to 'drive' the car while on jackstands and inspect the shaft for play or bending. just put it in first and let it idle or something while up on stands and make sure the shaft isn't bent.

pretty weird, but...

the problem fixed itself...

i was so annoyed of it so i went on the freeway smashing everywhere,
and then the next day noise and hardcore vibration went away.

but also i called driveline shops around my area, its about 85 to rebalance it
if it was still giving me an issue.

Thanks for the replies.

I had a 1 piece made @ Johny Franklins in Santa Rosa for a super good price. I ended up aliminating the rubber bushing on the back of the yoke,so I thought that had somthing to do with my shaft vibration. I also have SPL Subframe bushings so it doesn't bother me. Maybe balance is the issue? God luck good mod!
