Slip Yoke Question

[mag]

While working on my car this weekend I noticed the slip yoke on my Dynotech is longer than my OEM and that the driveshafts are of equal length. Is this normal and has anyone that has installed a Dynotech noticed the size difference?

Will the longer slip yoke prevent the slip yoke from floating and cause it to bottom out in my extension housing ?

No. With the IRS, the driveline is fixed in place, so there is no longitudinal movement of the driveshaft once bolted to the pinion flange.

JP nailed it. Many folks aren't aware the Mark VIII has a fixed rear differential (most IRS car do) so once the driveline is installed, there is no change in flange/pinion angle and no change in u-joint angle.

I have three driveshafts a 93 -97 and a Dynotech the 93 is the shortest slip yoke of the three the 97 is a bit longer and the Dynotech is the longest.So should I put my OEM yoke on the Dynotech or trust that it will work with the slip yoke installed.

I would run the Dynotech.

What kind of difference in length are we talking about?

If this is the same situation I had in my 98 LSC with the Dynotech the front yoke will just stick out a little bit more. No biggie There should still be plenty of engagement with the splines on the output shaft and once the rear pinion flange is bolted up, nothing is moving. If it doesn't bottom out in the trans it is no big deal.
