2nd gear vibration

[Rob]

Also with me, knocking at 2k-2.5k, the CSB was literally in two pieces, and the metal ring was seperated on one side of the mount. Replaced it, and about 2 weeks later, its back. Definitely a bad driveshaft...

FWIW, I just pulled my driveshaft because the center bearing was torn a few months ago and replacing it didn't help. I was getting a vibration around 2,000 rpm under acceleration.

I ordered a replacement from Driveline Service of Portland.

The old driveshaft had a really tight U-joint in the rear. No play at all, but very hard to move back and forth. I talked to the Driveline Service guys and they said that's the "classic" symptom of a bad driveshaft that will cause that vibration. The U Joint doesn't move, so the WHOLE DRIVESHAFT MOVES!

My CSB is torn as well. And I get a really bad vibration in the same range as everyone else. My guibo looks good though, it's not cracked at all.

Where could I find a GOOD replacement driveshaft and how much would I be looking to spend.

Also, is the driveshaft u-joint supposed to be easier to flexone way than the other. It flexes one way pretty far and easily, and the other direction not so much and it's harder to move.

My CSB was pretty worn out. I replaced it with a used one that seemed pretty good and I'm still having the same issues.
I have some known good used drive shafts that I can compare the joints too though.

Any luck with the driveshaft problems?

As to how to tell if the u-joints are binding...

One diagnostic is a failure of the rubber mount of the CSB. The other is to compare what the u-joints feel like to what u-joints in a new drive shaft feel like. If you don't happen to have access to a new drive shaft or have never felt the u-joints in a new drive shaft, go with the first option.

My CSB resently took a shit on me. Car was smooth until one day she went. I replaced CSB and guibo while under there. At first car seemed fine. Now i have vibration again through first and second but levels out 3 through 5. ?

Ditto... I just replaced my CSB and the vibration is still there.

How do I check for binding in the U-Joints? Mine didn't seem all that smooth when I moved them around out of the car...

i think i have the same problem.


shafts gonna have to come on out..
i have the csb

Cool, thanks. I'll try just replacing the CSB first. My guibo only has about 600 miles on it.

And with all that angry vibration it's probably begun to crack.

[KenC]

yep. I'd replace the guibo while you're under there, mine was starting to crack when i did the CSB and you might as well do both while you have the driveshaft off.

So you just replaced the CSB and all of the vibration is gone?

My CSB rubber was completely trashed and my u-joints are just fine.

If, as stated above, the shearing of the rubber CSB mount is usually caused by the driveshaft u-joints binding, is there anything on the u-joints that I would be able to see?
