CHEVY SHAKE FIXED!

[07Softail]

My shaking issue has been fixed so I will tell you what fixed mine and I would almost guarantee this will fix them all.

I was building up my 6l80 with some performance parts and sent my shaft out to a local shop to check balance, he said balance was perfect but it was out of true...meaning when he chucked it in his lathe it had 1/16 of an inch of runout in the center of the shaft. It was so bad you could obviously see it when spinning so he trued it and now my truck runs as smooth as glass with no shake, no shimmy, no vibration, nothing, it's never driven this good ever. So take your driveshaft out and have it checked. BTW it only cost me $86.00

Would you mind sharing with us what your symptoms were before-hand? Ive got a big torque converter shudder issue. My truck shakes like mad, shifting between gears and under light throttle. Torque converter was replaced and nothing changed. I also have and 8 speed with the 6.2 though.

Well my symptoms where just that.... a SHAKE! It would shake between 50-60 the whole cab would shake. It felt like King Kong was trying to shake me out of the truck. I could even feel it in the steering wheel at times it was so bad. I had my converter checked for balance in it checked out fine.

did the tachometer jump when the shake occured? and was it constant or intermittent?

No tach jumping, constant between 50-60. below 50 nothing above 60 nothing. Just get your ass under the truck remove the shaft and have it checked no need to look further.

Well,

It cannot hurt to spend $100 to find out just how bad they are and how much better they can be! It has to make the whole drive train last longer so all in all...worth the effort!

I think the concept is fascinating and makes perfect sense, any rotating part that is not running true can easily produce a shake. This boy may have cured the 800 page shake and vibration issue thread!! How would we find this shop that does good driveshaft work?

[07Softail]

I would venture to say any drivetrain or machine shop could check runout.

You could check it yourself with it still in the truck. Just put a dial gauge on a good sturdy mount or base with the back wheels raised and watch the dial indicator as the driveshaft is rotated by hand.

Also one detail I saw that you mentioned in the other forum that I think might help people

The local shop took one look at the brand of your driveshaft and said, "yup that's the problem"

Apparently the manufacturer of our driveshafts are known to have this issue?

I emailed them a long detailed message about it and of course no response. I am thinking there Quality Control or lack of is in question. We will see if they respond or not. BTW they are made in MEXICO! LMFAO!

0.0625''? that seems like a mile. how did they check it? did it have ton of weight on it? I'd expect .015'' as normal.
