Driveline Solutions ROCKS!!!

I got my old driveshaft off yesterday (after some prying) and boy are the splines twisted. I think that was causing my bad vibes at highway speeds..probably those twisted splines were locking up the DS and not allowing it to slide in/out on the output shaft of the trans.

So, Scott Koresky at Driveline Solutions (http://ls1lt1.com/ads/adclick.php?bannerid=57&zoneid=4&source=&dest=http%3A%2F%2Fwww.driveline-solutions.com) gave me a great price and excellent service on a new steel heavy duty 1350 driveshaft (M6/nitrous ready).

The best part? I ordered today and its shipping TOMORROW.

I will post pictures, etc. when it comes in (Friday hopefully).

Please give Scott your business if you are in the market for rear end components or a driveshaft, you won't regret it!

What about the output shaft on the tranny?

[Chris 96 WS6]

As far as I can tell (which is difficult to see up in there), the output shaft looks OK.

The car is still up in the air so I may get under there with a mirror and see if I can have a look further up in there.

The shaft didn't want to come off, which makes me think the output shaft could be twisted some too.

[gettinthere]

I'd guess that the output shaft might be a bit twisted too.

Niiiiice :thumbsup:

[LS13RDGEN]

If it is twisted and you end up needing to replace it, you mine as well get a rebuild kit and or steel shift fork.
EVERYTHING has to come off to replace the output shaft. :(

W/ the stock splines being so weak, I'd say Chris might have gotten lucky and not twisted the ouput splines on the tranny. He will find out when he goes to put the new drive shaft on and if its tough, they are twisted. If not he is ok IMO. The output shaft is stronger than the yolk, so the yolk will go first.

I thought about that, and you'll get the job if it comes to that. I just cannot afford a trans rebuild this year. The car will have to sit if the trans is damaged.

Cross your fingers for the Driveshaft :D

[Scott@DrivelineSolutions]

Well, did it arrive yet? UPS should have gotten to you today.

[Chris 96 WS6]

Didn't get it...will probably show today.

[Chris 96 WS6]

Came today!!! Will put it in the car Saturday... Its a great looking piece. $345 from Driveline Solutions!

[Chris 96 WS6]

It still has packing dust/etc. on it as you can see...

[Scott@DrivelineSolutions]

SWEET, get that thing in a roast'em! :streetrac

p.s. thanks for the pics with it on the garbage cans.! LOL.

[Flip94ta]

You may want to paint it.

If you take off the rear trans seal and hold the camera a few inches back you should be able to get a pic of it and you can blow it up and check it out

[Chris 96 WS6]

Yeah I was actually considering putting some clear on it to prevent rust.

Hadn't thought about the camera but with 5.1 megapixel I can take a pic with the Sony and magnify it pretty well.

[gettinthere]

Looks good man!

[Chris 96 WS6]

The trans output shaft must be twisted too. I took 3 pictures but still couldn't see all the way up in there. What I could see looked fine, but the new DS slid almost all the way on and then got a little caught and didn't want to slide back out, so I'm thinking the shaft must be twisted too.

After a trip on the interstate its obvious that the new DS didn't fix the problem.

Its either 1) the transmission, something speed related when the output shaft reaches whatever RPM is 65mph or above, or 2) the rear end. I really doubt its the rear, and to be honest this vibration existed before the rear end just not as bad and was only noticeable in 6th gear. I just thought it was a chassis vibration before.

I'm at a loss now and I'm out of money that I can throw at it. I am strongly considering selling the car again, even if I have to take it on the chin to do so.

I just don't have money to throw at it anymore, becoming a family man made sure of that. The positive thing is around town, off the interstate the car is a goddamn blast to drive and I enjoy the crap out of rowing through the gears.

[gettinthere]

Everyone always gets pissed and thinks about selling thier car. Take some time, keep it and everything will work itself out.

[LS13RDGEN]

Yank that 6 speed out and bring it over.
Let me take it apart first before you start ordering parts for it.
It might just be a bearing or something.
Who knows, we might be able to fix it for very little. :D

That's what I'm thinking. I want to check the pinion angle again first, and then if that doesn't help it has to be the trans. What's a viper output shaft cost?

The Viper output shaft is a different spline and diameter.

Do you have access to a dial and magnetic base? You need to check and see if you have runout in the output shaft.

[Chris 96 WS6]

Yes I do. How much runout is acceptable?

[Scott@DrivelineSolutions]

Yes I do. How much runout is acceptable?

For an output shaft I say 0 but +- .001 wou be ok. Can you see the shaft runout? Was the car in an accident or was the trans droped at some point?

[Chris 96 WS6]

The car's never been wrecked, but the trans is not original (used to be an A4 car)..

The trans spent most of its life behind a 500+hp 383 blower motor in a road-racing '95 TA, then about a year or so behind another similar HP Procharged LT1.

Despite the obvious (wear due to the HP input), the trans was in good working order when it came out of my friend's car.

Well wear wouldn't cause a vibration, something is bent of you pinion might be comming loose. My driveshafts are balanced past 10,000 rpm's, oh did you check the bushing in the tail of the transmission?

[Chris 96 WS6]

The pinion nut has not loosened. Sorry if I gave that impression. Trans mount bolts shook lose though. What's nuts is it really comes on all the sudden, rather than starting gradually and increasing with speed.

[Scott@DrivelineSolutions]

I have a 1999 Silverado 1500 that at 65 mph to 70 the passenger seat just shakes like mad. Harmonics and vibrations are some of the worst battles to fight with an automobile. I have done everything you could do to trace it down and I still have yet to cure it.

What are some characteristics of you vibration?

[Chris 96 WS6]

Hard to characterize, other than it feels like it is coming from the trans tunnel, and the whole car shakes like mad. Change rattles in the ash tray, and its loud....can't hardly hear over it.

Something in the transmission is going. Have someone go through it.
