Thanks! $53 is better than $470!
...if you want to be even more frugal, I usually take the one from the rear driveshaft, and use it on the front. Then put the brand new one on the rear.
The rear one's are often worn a little bit, but moving it to the front puts it in a different location on the splines. So you get to reset the service life.
The new style doesn't use the threaded cap, but uses a press on rubber cap instead. It's actually superior for holding grease.
So for $53. You can improve the rear, and lengthen the front.
This is how the legend of "all Bronco's are different..." is perpetuated.
Here’s a link of how to measure.
Follow the directions in the link and see how long of a shaft you need. I doubt there is an off the self unit that is the right length.
If memory serves me correctly the driveshaft is the same for a D30 and a D44
Nope. There is 0ne thing that the Spicer applications engineering group is really good at. And that is convincing Ford that they need to specify power transfer components to the 1/32 inch tolerance. So you will find driveshafts, and axle shafts that are different down to the 1/32. It's completely idiotic. But yes, 9 inch rears get different driveshafts than 8 inch, and the front 44 is about 1/2 inch shorter than the front 30. So different part number, (and you have to have some way to ID them.) Eventually Ford had to put the part number in bright yellow paint about 3/4 inch tall and about a foot long. I have no doubt that a fair number of 1969-1971 Broncos with Dana 44's ended up with Dana 30 driveshafts. When you own the forge, and you are machining driveshafts at a rate of 10,000 per day, cost is king. If you can reduce material consumption by using a shorter tube, and it ends up saving $.10 per unit. Someone will claim credit for a $1,000 per DAY costs savings. I call this "Six Sigma Math." This is the kind of lunacy logic that gets you an F250 with 7 lug wheels. Economy of scale has some weird results.
