Nope, look at the hubs on your ES..not onły are they different from left to right, but the each fit into the axle tube and support the wheel bearing.
Additionally I'm pretty sure they're not even the same from the 85 ES to the 86/87 models due to the redesign of the rear axle and brake assy.
Best look for the specific part to your year and model lest you end up with returns or spares for machines you don't own!!
Why are the Ontario newbs just saying 'Ontario' in their profiles lately?? Tell the people where you're from..
Secondly I may have what you need if I know where you are!
