What is this part? See photos. Should these be tight? Mine are hand loose. 2009 Yukon XL 1500 5.3 flex

Stabilizer bar links. Time for new ones and inspection or replacement of the stabilizer bar bushings where it mounts to the frame.

Thanks, I'll order a pair and swap them out!

Yup, stabilizer end links. Best to buy some new ones. That design has a problem holding moisture under that plastic sleeve and causing the bolt/rod that runs through it to rust and disintegrate, then eventually just falling off the vehicle.

Torque Spec is like 15-17 ft lb on the nut. You don't want to squish the bushing flat, but you also don't want it too loose to cause slop.
