GMC 2009 Yukon XL Owner's Manual page 493

CAUTION:
{
Wheel nuts that are improperly or incorrectly
tightened can cause the wheels to become loose or
come off. The wheel nuts should be tightened with a
torque wrench to the proper torque specification
after replacing. Follow the torque specification
supplied by the aftermarket manufacturer when
using accessory locking wheel nuts. See Capacities
and Specifications on page 5-122 for original
equipment wheel nut torque specifications.
Notice: Improperly tightened wheel nuts can
lead to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper torque
specification. See Capacities and Specifications on
page 5-122 for the wheel nut torque specification.
When you reinstall the regular wheel and tire, you must
also reinstall either the center cap or the bolt-on hub
cap, depending on which your vehicle has.
•
For center caps, line up the tab on the center cap
with the slot in the wheel. The cap only goes in
one way. Place the cap on the wheel and press until
it snaps into place.
•
For bolt-on hub caps, line up the plastic nut caps
with the wheel nuts and tighten clockwise by
hand to get them started. Then tighten with the
wheel wrench until snug.
