Vibration and Noise Issue

<------- That screen name is my nickname given to me by a customer after i was the only person to straighten out his issue, it then became Supershafts racing, and then it stuck and is now associated with my shop www.supershafts.com

At my shop i do driveline, mostly driveshafts, diffs, gv splitters....some performance suspension work.. all day, all week, all year....

I do not agree the driveshaft is balanced with the yoke attached

That is wrong and bs...
IF anyone tells you OTHERWISE there a bs shop.... Everything that is part of the shaft NEEDS to be assembled to the shaft when it is finished for balancing and NEEDS to be there when the shaft is being set up prior to welding...

I won't do anything without all parts of the shaft present..

I agree if the pinion angle is off it can introduce a vibration

I can't agree with you. I am very aware of even the smallest of vibrations and I especially don't ignore vibrations or any odd noises for that matter. Been a mechanic for nearly 30 yrs. now. Don't claim to be the best but I have had a ton of experience with drivetrains. As I said above I do not agree the driveshaft is balanced with the yoke attached. A buddy and me just had to shorten his driveshaft for a trans. swap we did in his truck and they didn't balance the yoke and driveshaft as an assy. Just the driveshaft. That's how all the shops I've dealt with did it. I have seen people leave off the inside C-clips which center the U-joint and that'll cause a vibration but it's not really all that common in my neck of the woods.

I have seen the inside clips left out millions of times.
Balanced thousands of shafts after the customer changed the joints, and then bought new tires, had the rear diff rebuilt, and had another yahoo group of mechanics make him spend close to $5k before they found me..

I have seen that more times every year then you could imagine... just last week with a cts v caddy

I would bet the shop doesn't even have a balancing machine.....Or they have a very simple balancing machine and it can not balance a shaft correctly (you'll be surprised how many driveline shops are a machine shop with a lathe, trust me) (we have 3 shops in NY like that, i get balancing work from them that they can't do since they can't balance shafts complete, but they fuk the customer anyway)


Any shop that will tell you they do not need the slip yoke of flange yoke though....I'll tell you once.... RUN ! ! !
