My 2010 Grizzly 700 was feeling a little loose in the front end, lots of play in the steering.
Turned out the upper ball joint was shot.
I ordered this Caltric one, part number BJ114-HHR, and it tightened everything right up.
It's a direct replacement for the OEM Yamaha part 5LP-23579-00-00.

It's made of metal and feels heavy-duty enough for trail riding.
Installation was bolt-on, so it wasn't too hard to swap out in the garage.
It came with a 3-month warranty, which is decent.
It's a lower ball joint actually, but fits the upper position on these models.
The Caltric brand has been reliable for me in the past.

It's a straightforward replacement part, nothing fancy, but it fixed the slop in my front suspension.

The ATV handles way better now, no more wandering on the trail.

If you've got a 2009 or 2010 Yamaha Grizzly 700 with EPS, this is the ball joint you need.

It weighs about 5.7 ounces, so it's a small part but critical for safety.
There's the usual Prop 65 warning for California, but that's on almost everything metal these days.

Good fix for a common wear item.
