How to fix slip yoke clunk...FOREVER?

You're still not tellin me where to put the ball. In the tranny or in the yoke?

The yoke is hollow inside when you get it apart you will see there is only one place to put it.

any other opinions on this problem??

the shop told me the springs are too soft and under load they flex, hencing the yoke slaps on the tailshaft. i read on fsc a guy who used hd shocks and took care of it. i just greased the shit outta my splines again, supposedly that works for a while too.

i wouldn't try it personally.

Spring and shocks don't have anything to do with the clunk itself, may be a cause for the yoke wearing in the first place though. the clunk is because the material of the yoke is much softer then the material of the splines on the tailshaft. the springs and/or shocks may have caused wrapping putting extra torque on the yoke, causing the splines to wear to a larger size, therefore the having slack between the yoke and tailshaft spline, causing a clunk when motion begins. when you come to a stop the yoke slips in one direction then when you take off it slips in the other direction at an accelerated rate and clunks. Yes, stiff shocks will reduce squat and inward motion of the yoke. But if you really think about it, when the yoke is pushed into the tailshaft more, more of the splines are in contact with the tailshaft splines, which I think would mean more suface area to grip onto and less likely to clunk. All the grease does is fills the excess space between the yoke and tailshaft spines and cushion the impact of slippage. the clunk is still there, just cushioned to a point where you don't hear it.

no..... the splines are so tight it would never make it to all of them. The grease would start to oze out the back of the yoke hole before it would ever begin to make it in the splines. My two pice drive shaft has a zerx fitting from the factory and I tried it. It did not work and just left a bigger mess to clean inside of the yoke. The only way I think it would work is if the diameter was larger only around the zerx fitting, thus allowing the grease to work all around the output shaft then back into the splines. I think that the zerx fitting would throw the shaft out of balance too.

well supposedly the new shaft they have available don't last and costs like 200 bucks or so. not sure on the price, just reading old posts and what not. all i know it's fucking annoying

agree'd, when I did the nickel plated slipyoke on my obs tahoe it cost like $500 w/labor, I'm not sure how much the yoke it self was but it definately fixed it. It never came back as long as I had it. I've it come back on other's but mine was fine. I'm curious to see if mine changes when I lower the back to the truck.
