Front Driveshafts

[GHarman]

Gonna do a swap between the '91 and the '93. The '91 was recently rebuilt. The '93 is really loose. Issue is that the u-joint at the front axle pinion is smaller on the '91 than it is on the '93. Who-da-thunk-it:-laf. Anyhoo, after talkin' with Joe at Drivetrain Industries, in Denver, I decided to take both driveshafts down for comparison. If the four bolt flanges, double cardan joints, tubes and slip splines are the same, he would swap out the small u-joint (and splined lower shaft) for the larger unit and still use the '91 driveshaft for a cool savings compared to a complete rebuild (quoted @ $300. 00). Hey! "Parts is Parts", right? Man, I'll get this scroungin' down (to a science), yet:-laf. GregH

Took both front driveshafts to Drive Train Industries, today. Joe looked at both and determined that the rebuilt ('91) Double Cardan had some slop and the rest was unusable for a replacement. He then checked the '93 drive shaft and said that the pinion u-joint needed to be replaced as well as the slip joint. The u-joint is no longer made but there is another method of repair using a different yoke and a special universal joint. He said the double cardan joint on the '93 shaft was still tight (original). The replacement u-joint is not greaseable? The slip joint is in the same situation. We shall see how this comes together. I'll pick it up next week. GregH

Going by memory the 89-92 front yoke is a 7260 similar in size to a 1310. In 93 it was made bigger to a 7290 which is close to a 1330.

I had a custom shaft made; a 1350 double cardon with 1410 front yoke.

Drive Train Industries is gettin ready to move. Joe did not mention any options othere than a different yoke and u-joint that replaced the original unit. At least this new slip joint is greaseable. GregH
