Noticed a good bit of play in the front right tire/wheel when going down the road and confirmed the tie-rod was bad by lifting the tire off the ground and moving the tire left and right. Ordered a new Tie-Rod for a bit over $110 with tax, so it must be some super deluxe part that will last into the next Millennium.
After removing the rubber dust boot I'm thinking it was never packed with grease. The gap between the ball and socket looks like the Grand Canyon and there is no evidence of grease! For reference the stud is 18mm and I believe a 3/16" bit fit in this gap. (See photos below)
After changing 50 or more tie-rods on cars over the years, I just assumed the tie-rod included the castle nut and new cotter pin. But Kubota is more forward thinking and elects to package the tie-rod LESS nut and cotter key. Nothing like a $9 castle nut and another trip to the dealer.
For the record the L4740 has right at 600 hours on it.
I'm likely going to take the boot off the new one to make certain there is grease in it. Also tempted to see if a zerk fitting can be added.
Of the several common design methods for ball joints this is the cheapest design out there, yet priced as a premium part. I don't mind paying for quality but this certainly doesn't look to be the case with this part.
Referencing Messick's, this part is used on 25 models ranging from L4240 thru L5740, L4760 thru L6060 and Mx 4800 thru MX5800.
In the event it is useful to anyone, the stud thread size is 18-1.50 mm (fine pitch).
