Cripes!!!.....Jeezus.... You have to be kidding!!!...I wouldn't crawl under that. the only real support you have are the jackstands under your rear subframe...those loose blocks and jackstands under your axles do not count. Maybe they are already there....I just can't tell from the picture though...If not then you need to add two more jackstands under your front subframe to make that stable. Never trust jackstands placed under flexible suspension components like axles and a - arms. Jackstands are meant to be palced under ridged components. Jackstands also like to be level...if your front tires are on the ground and the rear is up on stands, there is a chance that the jackstands can slip as well.
