Does anyone know where to get aftermarket splines yokes. I am rebuilding the propeller shaft for my 04.5 400 sportsman and the dealer wants over 100 for each end. They are 22 spline approx. 1" in diameter with #338 u-joints which have approx. 1" end caps.

 

try google-ing it. i didn't have much luck whenever i had to replace the yokes on my '02 expedition. i either could not find a company that would sell retail or i had to buy 100 of them.
my dealer wanted $80. i finally found a driveshaft off a sportsman ,off of e-bay,that shared the same part number,as what i needed for $20.
One place i didn't try was the john deere dealer,it seems as though some of their utv's share the same front end parts as the sportsman's so maybe........
GOOD LUCK and let us know what you find out
also that u-joint can be had at about any auto parts store. it's just a regular pto- style joint,if they have any trouble sizing one up ,have them look up a steering shaft joint for a '99 international 9400 ,should be exact fit.

 

Ebay will be your best bet for a slightly used oem cheap. Is yours bad? They tend to have some play in them which commonly gets mistaken for being bad. Did that on my 05 800 only to find that after spending the $ to replace them they were fine.

 

I knew about the u-joint, 60 at dealer 19 at local auto parts shop. The rear yoke has about 3/16" of play at the u-joint. At 40-50mph there is quite a bit of vibration, I removed the shaft and vibration is gone at those speeds. Both u-joints are good. My only hope is that the transmission shaft is not the worn part. I read somewhere that the trans,diff shaft are hardened and the prop shaft yokes are not so they will wear. I went through a spicer/dana catalog with no luck.

 

You are correct on the shaft and yoke hardness. If it is excessive enough then you probably could use new yokes. They are definitely pricy at the dealer. That's why I look to ebay for most of that stuff. Save a ton of $ if the parts are available!
