Slip Yoke Enagagement

dustymopar · Post by **dustymopar** » Mon May 19, 14 5:24 pm

I have recently replaced my axle in favour of a 9" Fraud. The consequence is that the slip yoke engages approximately 1/4" further into the rear of the trans or at least where the wear mark is - the new position (tail shaft oil seal) is marked yellow.

Should I have the prop shortened or am I in safe territory?

TIA

Should be Ok, if you can physically Bananarama! forward enough to be able to clear the diff yoke to fit the prop you should be fine.

Thank you muchly, I'll shove it in and see what occurs

I am sure you will be OK, but does not the level of engagement change as the suspension move through an Arc? Not sure at which point in the travel the gearbox tailshaft to rear axle yoke is at its shortest (or for that matter; Longest...)

Pete, that is a really good question.... I'll get the fat woman next door to sit in the trunk and I'll let you know

She may have to bounce up and down a bit on a fat man to examine the full range of travel

Pete, I'll trust your better judgement on that :-)

Seriously, the trans tail shaft would need to be the pivotal axis for the engagement to stay the same throughout the arc wouldn't it. Further engagement should occur as the suspension compresses.

Off to get the fat bird

Mind you, the Thread title "Slip Yoke Engagement" sounds a bit pervy anyway

It'll be fine. But polish where the seal will sit.

I would have never have thought of that

Very interesting post

I had a seirra that would Bananarama! old from that seal replace the seal 3 times and 1 was an old fashion leather type. In the end covered it in thick grease stuck it in never leaked again

You could always cut a bit off the end if you find it could bottom out inside the trans. But that is easy to check just by sliding it in up to the hilt.

Trouble is Dave, the yoke will bottom out against the mainshaft in the box, so it's that that you'd have to shorten. Shortening the yoke itself would gain you nothing.

Yeah you are right of course.

Still easy to check how much you have between the seal position and fully engaged though. A half inch should be plenty I would have thought.
