SLIP YOKE

[Fred]

Hi Guys, I'm wondering about my slip yoke.  The rear end  is a 8  3/4.   The  transmission is a 727.   The length of the driveshaft  is 52.07 inches.
I'm not sure if the 2 inches of the slip yoke showing (see picture) is too excessive.
Any ideas?  Am I worrying  for nothing?
Fred.

Looks like too much for me, i would be worried about that coming out. Has someone shortened your tailshaft.

[Fred]

No, no ones touched the tail shaft, it's what it should be (52.07 inches).

It is your transmission rear seal you don"t have the normal looking rubber one that protrudes out about 1/12 inches from the end of the box. plus your diff end normally has a dust type metal cover over the seal as per factory it is a part of the yoke. your one has been changed. That 2 inches should be fine.

You may have a driveshaft intended for use with a Dana 60, which is about 1-1/2" longer in the snout. If you have less than 1-1/2" spline engagement I'd get a new shaft.

The absence of a dust boot on the seal gives the illusion of too much yoke showing but it's most likely OK.

3 3/4" from the end of the housing to the center of the u-joint is the correct "at rest" position.

Thanks Mate for the help. I will get onto that seal.
My car came with a pinnon yoke which had a metal dust cover on it but I had to up grade to hemi specs so I had to change to a 1350 series pinnon yoke.

Thanks for your help. My specs are..........the slip part of the yoke is 6 1/2 inches, the output shaft protrudes 1 inch out of the extension housing.
Which means the yoke engages 5 inches with the splines of the output shaft.
So I should be fine. Am I correct?

I worried for nothing John, I just measured mine and it's spot on (3 3/4") So thankyou very much for your help.
I'd already installed a bolt-in drive shaft loop because I was a bit concerned but now I can rest easy.
