Was putting everything back together after replacing both rear wheel bearings and trailing arms on the Santa Fe, and realised I'd bent the end of the upper control arm ball joint on the left hand side. Went to pull the upper control arm out (ball joint is integral with the arm!), and realised the mounts are ON TOP of the subframe and inaccessible without dropping the subframe! Looked at my little trolley jack. Looked at my scissor jack. Looked at the tractor jack. Wished I had Pedro's hoist. Went for a beer.
