I have been searching for u-joints for the steering shafts again, and my usual suppliers seem to having stock issues.

I searched around in the threads for old links and sources and found a bit of a mess so after finding out tons of additional information about part numbers and such, I thought I would leave a single thread with as much information as I can

I'll divide this into the two sizes of u-joints. The 16x40mm early un-staked type with the snap rings, the later 15x39mm ones that you have to deal with the stake and un-stake. Won't get into how-to in this thread, just sizes part numbers and companies etc

First the early 16mm x 40mm style with C clips

 

Previously I could find them using the ATV700 part number.

These come from this specific Kawasaki ATV

Kawasaki Bayou 300 front driveshaft u-joint set 1989 - 2004

Kawasaki OEM part number  :   49050-1055

Once I knew this I was able to google that part number and found plenty of suppliers

BTW, this is all confirmed through a local Kawasaki ATV store here in Calgary. He can get them for $37.99 CAD each. 

Ebay has them too.

As does Amazon.ca,   $46 each, 4 day delivery

They mention the model # of the ATV, KLF300C

They also mention it fits "Mule 2510 4x4 1993 - 1999"

Ebay mentions there manufacturer is East Lake Axle  and their part number is U201.02

And the really cool thing? All these U-joints have zerks.....

And some specs from

Now for the later PITA ujoints,  15 x 39 ujoint for staked yokes.

A thread where these were discussed with a part number

https://www.driveshaftparts.com/index.php?route=product/product&product_id=1100

Part Number: UJ1540SD

They indicate they are out of stock as of today.

They indicate a length of 1.535 which converts to just under 39mm, even though the part number suggests they are 40mm (1540SD)

I have a pair of these in my hand, confirm part number and fitment.

 

Added a resource to this complication thread.
