Repair guidance for this model year

Heads up for 1998 Lincoln Town Car owners: Vehicles this age frequently have seized fasteners due to thread corrosion. Apply penetrating oil (PB Blaster, Kroil) 24 hours before any wrenching, and have a thread chaser on hand. Lug studs are particularly prone to thread damage at this age; if a nut spins on without engaging, the stud is stretched and must be replaced before the wheel goes back on.

Tools you will need

Metric socket set (8mm-22mm), 6-point impact-rated
Calibrated torque wrench (10-150 ft-lbs covers most automotive jobs; add a 0-250 ft-lbs wrench for truck lug nuts)
Breaker bar (24" minimum) for initial loosening
Penetrating oil (PB Blaster or Kroil) for any fastener over 5 years old
Anti-seize on stainless or dissimilar-metal threads; thread-locker (Loctite blue) on critical reassembly
