I own a '00 trail boss and since i only have a tight space to park it in, i have to lift up the rear of the quad stretching out the back suspension. After doing this a few times a realized that the back suspension is now much stiffer and and creaks and moans when i push down on it(doesn't sound very healthy). Is this ok and is there anything i can do to fix this?

 

yeah, you should grease the fittings on the top of the swingarm...

 

I have the same "tight fit" problem. However, I find it easier to lift the front end, it seems to be lighter and easier to lift to me. I back in the rear end, then lift and swip the front end around. No squeaking here!! (Except for the time I washed all the lube off my rear shock).
