You mean the spring not the clamp, right? Thats #14 and it along the one on the other side hold the tub up.
The easiest way to do this will be to get the part first, part #134362800 and a WHOPPING $5.65 from Sears, maybe cheaper from your local appliance
parts dealer. Then, locate the hole on the center/upper part of the tub where the spring connects, connect it, lift the whole tub assembly (Its very heavy!!!) back up and hook the other end of the spring into the frame. Now the machine is basically fixed, but you need to look for further damage below so , on this machine, since there is no lower-front access panel like there used to be, remove the screws from the rear access panel and look at the shocks to make sure they are connected securely to both the floor pan and the bottom of the tub. From this perspective, the pump will be harder to see but you can see it all the same and watch it as you run a cycle to make sure its not leaking. The only other concern down there is the motor controller (MCU) which if damaged, will keep the motor from running so its pretty obvious if theres damage there. Check ALL wires that you have access to for breaks in the insulation and repair as needed. Watch the cycle for awhile and make sure there are no leaks or other obvious problems, being careful of the moving drive pulley. If all looks ok, then all IS ok and you can put the panel back on and thats it!
The other way to check without buying the part first is to have a strong person that you trust hold the entire tub assembly up where it should be while you do the same thing I just described. All of this is easier from the front but in the infinite wisdom of the Frigidaire Corp, there is no more front access to the machine that can be opened WHILE the machine operates, so taking the entire front panel off which is what you now have to do for front access is pointless except for a cursory, non operational inspection.
