  • The short-wheelbase TJ paired 2.5L four-cylinder or 4.0L six-cylinder power with manual or automatic transmissions.

Worth knowing

Notable

  • This record uses the 1999 U.S. powertrain and body-style range rather than borrowing a neighboring model year.

Living with it

Reliability & ownership notes

  • For a 1999 Wrangler, inspect frame and body corrosion, steering/suspension wear, four-wheel-drive operation, modifications and service history; verify engine and transmission by VIN before ordering parts.
  • Check the VIN in NHTSA's recall lookup for unrepaired safety recalls.

Maintenance & service parts
