Yamaha YXZ1000R Ball Joints Replacement

Finding a bit of play in the suspension of a Yamaha UTV during the pre-ride inspection is an indication the ball joints have worn. 

Replacing both the upper and lower joints at the same time is recommended because when one wears out, the other will soon follow. Plus, if you’re going to the trouble of dismantling your machine, might as well get them both done. 

Watch the video above and follow the steps below to replace the upper and lower ball joints on a Yamaha YXZ1000R.

Removing Yamaha YXZ1000R Upper & Lower Ball Joints

Step 1. Raise the vehicle and support it on heavy stands positioned under the frame, then remove the front wheels.

NOTE: Don’t work on your side-by-side or any other vehicle using only a jack. Always make sure the vehicle is safely supported on axle stands.

Step 2. Remove the 32mm axle nut and washer.

Step 3. Remove the two 14mm brake caliper mounting bolts and slide the brake caliper assembly off the rotor. Unfasten the brake hose bracket (10mm bolt) from the lower A-arm, and use a zip-tie to hold the caliper assembly out of the way.

Step 4. Slide the wheel hub out from the steering knuckle assembly.

Step 5. Remove the cotter pin from the 19mm castle nut that holds the steering joint, then remove the castle nut and washer.

Step 6. Remove the steering joint from the steering knuckle assembly. Use a dead-blow hammer to knock it out if necessary.

Step 7. Remove the shock absorber mounting bolt (14mm bolt, 17mm nut) and slide the shock absorber from the upper A-arm. Use a bungee cord to hold the shock absorber out of the way.

Step 8. Remove the cotter pin from the 22mm castle nut holding the lower ball joint, followed by the castle nut itself.

Step 9. Thread a disposable 22mm nut onto the lower ball joint to protect it and knock the ball joint free from the lower A-arm with a hammer. Using a disposable nut prevents the castle nut from being damaged.

Step 10. Slide the CV joint out from the steering knuckle assembly.

PRO TIP: At this point you can remove the driveshaft to give yourself more room to work with. To remove the driveshaft, simply pull it out from the transmission housing.

Step 11. Remove the cotter pin from the 22mm castle nut holding the upper ball joint, followed by the castle nut itself.

Step 12. Remove the circlip from the top of the upper ball joint with a pair of snap ring pliers, then knock the ball joint down and out of the A-arm with a hammer.

Step 13. Remove the three 4mm bolts and the wheel guard from the steering knuckle.

Step 14. Remove the circlip from the lower ball joint, then hold the steering knuckle in a vice and use a hammer to knock out the upper and lower ball joints from the steering knuckle.

PRO TIP: You’ll need to use a metal collar with an internal diameter that’s wide enough to fit over the new ball joint’s boot, but sits securely on the outer edge of the ball joint itself. We found a 54mm driver collar was a good fit, but you can use a section of metal pipe or something similar.
