    I am lookin to upgrade my rear driveshaft in my '90 with the 241 t-case. Currently it has the stock shaft with 1330-series joints and I'm running a 1330/1350 conversion joint for the 14FF rear.

    I don't really think I need a CV shaft....I don't drive it daily and I will have a trailer soon. The stock shaft seems to be okay, and with a lengthened shaft it will have even less angle.....

    Anyway, what, if any, stock applications had a 1350 rear driveshaft with a slip yoke that fits the 241 output? It sure would be cheaper to find a shaft out of a pickup or something and just have it shortened!

    Your current joint is a Saginaw 44. The easiest way to go to a 1350 shaft is to get one from a 81 and up manual trannied K5. These shafts have 1350 joints. I know this because I have one.

    Also, the shaft is the same for 241's and 208's.

    A newer (i.e. one with a 208) Blazer with manual trans seem hard to find. I would assume then that a 1/2 or 3/4 ton truck with a manual would have the 1350-series shaft also.

    Also, is the Saginaw 44 joint basically the same as a 1330........the 1330's sure do fit good in the stock shaft /forums/images/graemlins/confused.gif

    I have a 1990 v2500 suburban. It came with a sm465 & 241. The rear slip yoke drive shaft has a 1350 yoke for the original 14sf.

    The saginaw 44 is not the same as the 1330. I can promise you that you dont have a 1330. /forums/images/graemlins/smile.gif Unless you swapped it in a later date. The 1330 is similar, but will not fit. I have tried /forums/images/graemlins/wink.gif...

    The manual trannied trucks also will have the 1350 joint.

    is that 81+ manual shaft a cv shaft? not trying to hijack, but if one wanted to go to a yard and get a rebuildable 1350 CV shaft, what kinda donor rigs would work best? ok, maybe that was a post hijack... /forums/images/graemlins/wink.gif

    What exactly is the difference between the 1330 and saginaw 44?

    My rear driveshaft calls for the same u-joints at both ends. I replaced the one at the rear diff with a Napa 447 conversion joint, which I believed to be a 1330/1350 combo joint, and it fits with no problems. /forums/images/graemlins/confused.gif

    The napa 447 is a Saginaw 44 to a 1350 U-joint. I have the Neapco catalog and cross reference in front of me. /forums/images/graemlins/smile.gif

    See in particular the joint sizes for PN's 2-1153 and 2-3050. You will see that the 1330 and S44 are different sizes

    Now see what the application chart calls for..

    Now see the size of the PN 2-3011 [ The S44 joint ]

    The above catalog cuts will show that you do have a Saginaw 44 joint in your rear driveshaft. A lot of people think its a 1330, including myself until I went through hell (read $$$) trying to get what I needed. People were telling me all kinds of different things. But until I actually did the research myself I had no real understanding of what it was.

    I hope this helps and clears up any confusion. (Most likely will stir it up more) /forums/images/graemlins/thumb.gif /forums/images/graemlins/grin.gif

    I had numerous problems with the Napa 447 joint. It did not last long and broke easily. I finally had a new shaft made with Spicer 1350 joints and it has cured the problem. No more broken anything. Note that I was using the 447 the other way at the time... 1350 in the shaft to S44 on the axle yoke

    Lastly, please understand, I am not trying to come off as an ass, I just want everyone to know what I know about this subject. It makes it easier when buying parts and giving out information /forums/images/graemlins/smile.gif /forums/images/graemlins/thumb.gif
