DIY for Rear Shock Absorber, anywhere?

[LeiZ]

I did my homework, but the search result didn't provide too much related to rear shock absorber. It's mostly air suspension related. Mine is non-air.

Last night finally pulled all the cover and found out where the shock amount is. But if there's a DIY or procedure of some sort, that'll be fantastic. Otherwise, you'll see a DIY write-up pretty soon, with all the mess I'm about to make.

By the way, do I need to put some bricks under the wheel before I take the shock absorber off?

Thanks, guys!
