Bent rear center shaft??

[Steveoarrma517]

Got a arrma felony and when inspecting the drive train by rotating the center diff by hand with no motor installed I am noticing a lot of run out on rear drive shaft. It appears to be bent more then I would like to see. Any body experience this with felony or other on road 1/7. Probably have to remove to see before 1st run even. New car.is this common? One side of shaft hits suport bearings an other doesn't makes me think shaft bent from factory.

My limitless came with both front and rear DS with a slight bend, made the car vibrate. I bought better DS.

Haven't taken out yet and I was looking online at some DS already. Brand did you go with.

I ended up buying a no name steel set off ebay. Cost like $26 bucks for both, worked perfectly too. They are still on ebay, sellers name is rcawd1999

Got my new drive shafts installed. Question to you is...did you remove bearing center supports with rcawd drive shafts?, due to the thicker diameter the shaft is riding on both bearings all time. Shaft doesn't want to float now,worried it well cause heet restance on motor.

These rcawd shafts are thicker .250.. stock.195 thousands. Probably going to remove, my 1/7 talion stretched on to a mojave chassis has just as long a shaft,no bearing support, no problems.

Shafts are not bent on my other 1/7,and they fit nicely between drives also,so do these. Nether are running out of round.

Mine didn’t have that bearing and if it was mine it would be in the parts bin.

Most likely an earlier version like you said. I built this over 2 years ago and sold it last year. This pic still has the OG DS's

Yes, I flipped the CD. BTW, that cap pack didn't do for any of my runs. I don't look at computers and "stats" for ripple ETC. in RC cars, if breaks, I get a newer and better one.
