    my frien was looking at my front drive shaft and he says the yolks bad. he said i could get a shop to redo it or find a good used one. just wanted everyones take on it. it will be winter in4 months or so and that means the rain and mud start in 2.

    thanks

    he said that the yolk would have to be cut off and a new onw welded on. the problem is that there is slack in the slip joint. it can move an inch or less in any direction. ther shouldnt be a problem with running wo a front should there?

    i have a 350/th350/np205 going to a stock dana 44 gears unknown
    thanks

    I've run without the front shaft for a couple years. If you don't 4 wheel any, you actually gain power from less recipicating mass (even with the wheels free wheeling).

    Since I'm doing the whole restoration bit, I finally got to the front shaft which had a couple really bad u-joints. They're actually quite easy to work on, but without the shaft on the bench, it could be easy to mistake the actual damage (with all the grease and dirt that's likely).

    the u joints at both ends are good, but the middle is sloppy so i will pull it out and see if it something i can fix or not. If i have to help someone while its out i have my winch. /forums/images/icons/grin.gif

    my front shaft also has that slop and its because i pulled it out from each other off a big bump i hitand caught a couple inches of air and pulled the slip yoke apart.i would replace the shaft as i still have to also.

    So mine appears to have bent splines, it won't telescope out more then an inch. Maybe that's why the U-jounts were trashed so bad, or maybe the trashed ujoints caused enough slop that the splines twisted...

    To fix is $220, anyone have a front shaft?

    i havent taken mine out yet.need to replace mine also.splines badly stripped.mine just has 2 ubolts holing it in i think.1/4 inch drive socket should fit in there to get those off.or an open end wrench.on mine it has the crossmember in the way so it will be a tough one it looks like.

    Give NARA a call on the yolk, I think they carry it.

    The back one is hard to get off, I think part of the problem is that the bolts are a little too long. If you take the body off it's real easy to get to... /forums/images/icons/smirk.gif
    Actually if you can clean up the area, it helps because it's really tight in there.

    BTW: I have contacted 4x4 doctor and he doesn't have the u-bolt type. I may have to get mine rebuilt.$$$

    I have a front shaft out of a 69 blazer that had a 465/205. It is frshly built from drive line service in Colorado Springs, Still has the stickers on it. I flipped the blazer. I will take 75 bucks plus shipping for it. Measure the length of the old one so I can measure this to make sure it is right. If you are interested email me.
