2nd gear vibration

[accident]

I'm having this same issue now. Is it easy to tell if the rubber mount of the csb has failed?

What should I be looking for? I'll probably just end up putting in a whole new driveshaft assembly.

The rubber around the bearing itself will usually be shredded or at least torn if this is the case. I cant remember if the CSB is under one of the underbody pieces or not, but you may be able to see it through a space in between them if it is.

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?

[accident]

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

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

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.

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.

i think i have the same problem.


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

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...

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 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?

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.

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!
