Drive Shaft Angles

[krh9848]

Not really avoiding an SYE just waiting on the funds to purchase one. As I stated earlier and was trying to get an answer for was the coast down vibrations do not happen at set speeds but at random speeds during coast down. I know that the acceleration vibrations usually occur at a particular speed range. So I thought that driveline vibrations would have set areas of speed range during coastdown as well. I am just wondering if this is driveline related and that's why I asked if anyone has experienced anything similiar to this.

I had the decelleration vibes you're experiencing when I installed my RE 4.5" lift. After playing with angles for a while, I found that it was the yoke at the transfercase end having insufficient engagement and "slopping around" when drive torque was removed from it. This is just what Eagle described. I know you have the "long" yoke and have said it looks and feels good - but I'll bet you this is your problem. I've read here that that long yoke is only marginally longer (what was it - 1/8" or something really insignificant like that?). Did you measure the difference in the yokes when you installed it?
My JB Conversions SYE and Tom Woods shaft took care of my problem completely.
Good luck.

BTW:
I drove around on mine making that sound (and making me cringe at the thought of what it was doing to my rig and WOULD do if that driveshaft dropped out of the t-case and pole-vaulted my Jeep) for about a month before I got the SYE and DC shaft on it. When installing the SYE, I checked out the splines on the end of the original main shaft and to my surprise found that they looked ok. I don't mean to suggest that driving around like that is a good idea, but merely that with a little luck you too might get away with it until you get an SYE. Just watch out for that pole-vault effect!

Did yours vibrate during coastdown at random times? I bet that may be problem. I appreciate your response to my question. Hopefully I will be able to install a SYE very soon.

Thanks again to all who have responded.
