yea one side is left handed threads for lugs. The top of them is stamped with an L
for rear springs you better be able to lift and carry about 90 lbs to move em about and somewhat safely slide them off.
When i took mine off i found it easier to remove the front shackle so its only being held by the big pivot shaft, then spray with liquid wrench and rock it back and forth (granted the rear clam is removed and axle is out of the way). then should slide off. Usually the spring pivot shaft thats riveted to the frame is worn because of lack of grease on the brass bushing.
Disassembling the leafs themselves its pretty straight forward, there isnt much tension at all when their fully together so not much to worry about. They might spring a tiny bit but wont send it rocketing around.
that pin is usually worn. vendors sell new ones for about $21 a pop along with the new bushings (not too cheap tho)
yea i will agree the AA is about 3x beefier parts...Better get a nice impact 6-point socket set and invest in PB blaster or liquid wrench. Along with various "torque multipliers" slid over breaker bars....
So moral of all this if you cant lift 90+ lbs and be able to support this at weird angles (dont want to damage the threads on that pivot shaft) definitely get help. They are a weird object to carry as it always wants to flip upside down (so dont leave them sitting upright in the garage - lay em flat as they can fall over and smash toes and fingers)
For those of you who need a size comparison that socket rachet and socket are all 1/2 drive... bottom leaf is a good 2 feet long and about 1/4" thick.
