How much play is too much? When I installed the driveshaft and bottomed out the trans yoke I took a measurement. Installed the joints into pinion yoke and took another measurement. I got 1.180". Is that extra .180" too much? I plan to call Dynotech tomorrow morning, but wanted to see what your guys opinion was.

I push the tranny yoke in all the way until it bottoms out on the output shaft of the tranny and the slide it out 3/4 inch and go from their on the effective center to center length That is with the chassis compressed (weight sitting on all four wheels ) like it will be sitting on the ground, not with the rear suspension hanging down unloaded

Thanks Cab. I did measure at ride heigth. Dynotechs online order form shows 1" for movement. Just not sure if that .180" is too much?

The "bottom it out and pull back one inch" only works with a rear seal that doesn't have the dust boot.

The factory dimension for the 727/833 slip yoke is 3 3/4" from the rear of the tailhousing to the center of the u-joint.

It'll be fine. That leaves plenty of yoke surface to ride in the bushing.

Hi john, Is the yoke dimension in the factory service manual or the parts manual? I have been thumbing thru 1966 to 1969 section 16 and can't find it. thanks, ronnie

The dimension is from the Mopar Performance chassis manual.

thanks john. I know I have seen those fac pics dozen of times on page 185 for autos and page 226 for manuals. the mopar chassis book was right in front of my eyes,but I kept thumbing thru different years of service manuals looking for that info.
