Common fastener categories on the 2021 Land Rover Defender 90

Wheel / lug nut torque and thread spec (covered above)
Brake caliper bracket, mounting, and slide/guide-pin bolts are different fasteners. Confirm the exact axle, application and service-manual specification before reassembly.
Engine oil drain plug torque and tool size when this vehicle has a verified drain-plug record
Transmission pan, valve cover, and intake manifold bolts where the database has exact records

Repair guidance for this model year

For 2021 late-model work: Modern vehicles increasingly mix aluminum, high-strength steel and coated fasteners. Use the exact fastener record and service-manual procedure for the joint you are touching; do not adjust torque or add compounds unless the procedure calls for it.

Tools you will need

Metric and SAE socket set (8mm-22mm plus 1/4"-7/8"), 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
Replacement washers, threadlocker, anti-seize, or dry-thread preparation only when the exact service procedure specifies them

Frequently asked questions

Are the 2021 Land Rover Defender 90 fasteners metric or SAE?

Metric and SAE hardware can both appear on one vehicle, depending on the component and exact application. Use the individually verified field and the actual fastener or service manual rather than inferring a standard from the model year, make or generation. Bolt-head markings can help identify the hardware at the bench.
