There is a lot of good info in the threads linked by T-Man403, and of course things to watch out for, as seen in LadyRiders thread. Doing the work myself doesn't scare me much, but I'm not sure I have all the needed tools. First off, I don't have a lift. I was looking into making the cheap wood lift, as found all over the internet and this site. But I'm not sure if it will get the back wheel off the ground enough to remove it.
From pictures in previous threads, it appears that my rear drive seal is leaking from the back side between the drive and the hub. I will check the breather hole at the top, like Gene suggested. If it is just the rear seal, it sounds pretty simple. My fear is that once I get it apart, I will find more than I was expecting. I am not quite prepared to disassemble the driveshaft, as I don't have an impact wrench or even a vise to get it apart. I am sure my splines will need some grease, also. I just hope I don't find what LadyRider did!
I suppose I could always just take the drive down to the shop and let the pros take it from there, but I like to be able to do these things on my own. Much more satisfaction knowing how everything was done.
I want to rip it apart right away, but I have to solve the lift issue first. Can't justify the $80-100 on a lift right now-even though I know it will become an essential part of my workshop.
