This is a critically important part!!! It is an alignment shim for the trailing arms. If it has fallen off (which it obviously has) then one of your trailing arm bolts is no longer tight, thus has play in it, will cause other shims to fall off if present, and most importantly will cause dangerous wear on your trailing arm bolts. Check both trailing arm bolts. If only one of them is loose, you know where the shim goes. Take note of the number of shims on each side (hopefully that is the only one that has fallen out), then remove both TAB (trailing arm bolts) and inspect. If either are bent, replace them. If they are not bent, clean, lubricate, reinstall with correct shims for each side (for rear wheel alignment). Torque down to about 55lbs and then double-nut them.
