The SX drum turns, add water and dirt to that and you have a muddy filled drum, then it eats at the seal and outer bearing. Then the ring gear seal and bearing.
The 86 has an inner drum which is protected by a cover and a much smaller seal rather than an 85 whole 7" drum turning on one giant seal.......
The 85 also had an issue with the swingarm boot. If it has an XX stamped on the swinger, they glued it back up. I always siliconed them, lightly tightened the clamps and finished tightening the next day. The swingarm pivot area also needed attention.
My boots also tear up the rubber protection boot.
An ES just gears you down a bit.
None of these things like water, do you blame them?
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
