Rattlewagon 08-07-2005, 11:13 AM I posted here; http://dieselplace.com/forum/showthread.php?t=39962 about a acceleration shudder but I'm getting nowhere with the dealer, can anybody with a CC Allison tell me from the centers of the u-joints how long their D/S is??? :help: thanks dan ABQFirefighter 08-10-2005, 06:23 PM I had a 2-piece steel shaft in my '01 2500HD, but I was having the infamous 'shuddering' when I started towing my 5th wheel. After an extensive search, I found that the dealer wanted about $700 for an OEM shaft. I found a guy off of Ebay that builds aluminum shafts. I gave him the part number off of my friends 2003 CC/SB and he built me an exact OEM Spicer referenced one-piece aluminum shaft delivered for about $250. Guess what, no more shuddering. hd90rider 08-10-2005, 08:00 PM I also have a slight shudder between 45 to 50 mph & then it quits. Is this the same thing you are experiencing?? ABQFirefighter 08-10-2005, 09:05 PM My shudder was from 0-15 when towing my 5th wheel. When not towing, it was from about 30-40 and then again from 60-70. Replaced the crappy 2-piece design that GM released a TSB about with the one-piece.

ABQFirefighter you don't happen to know the measurement of the shaft from the centers of the u-joints do you? Good to meet another firebug! I'm a proud member of Station 42 VFD Morris TWP!:ro) Big red trucks are cool!!! ):h hd90rider 08-12-2005, 07:12 PM I have the shudder loaded or empty. ockgator 08-12-2005, 09:47 PM I'm not lucky enough to have a one piece DS. But I am lucky enough to have a truck with a wheelbase longer than most cars total lengths. Did have small shudder after 4" lift install but used front end align shims to correct.

Replaced the crappy 2-piece design that GM released a TSB about with the one-piece. the shaft builder didn't happen to be ujointmaster did it? ABQFirefighter 08-16-2005, 10:39 AM Yes, why? Rattlewagon 08-16-2005, 11:44 PM Yes, why? After I read your post I did a search on ebay and the only one I found was ujointmaster, their feedback seems to be excellent. I hope I can assume you have been satisfied with their service and quality of their product. I plan on contacting them as soon as my dealer tells me that I am completely out of luck as the shudder I feel is "completely normal!". After all a custom built D/S with new ujoints for less than $300 is a steal in my book! ABQFF, my D/S is about 73 1/8 long what was your final dimension? Did you have to give it to them or did they know? thanks dan ABQFirefighter 08-17-2005, 12:20 AM I crawled underneath my buddy's 2003 CC/SB and got the Spicer #, not the GM # off of the shaft tag. He was able to build the correct OEM shaft, with new u-joints. The new shaft had a a Spicer tag on it and all. I only had to use my OEM yoke off of the old shaft. Give me another day or so and I'll get you that Spicer #. | ||
