1989 Bronco

A peak year with unresolved numbers

The 1989 Bronco continued the all-EFI fourth-generation formula and added electronically controlled automatic-overdrive availability, though its exact annual total remains disputed.

This page covers U.S.-market 1989 Broncos. Surviving research is thinner on year-specific cosmetic changes than surrounding years, so it emphasizes verified continuity and openly records two production totals—69,470 and 66,730. Sources also differ on whether E4OD availability should be dated to 1989 or summarized from 1990.

Why it matters

Whichever disputed total is used, 1989 is the fourth generation’s strongest published annual result.

What this page covers

Market: United States; fourth-generation Bronco.

Body styles: Two-door full-size wagon with removable rear hardtop

What changed for this year

Mechanical continuity
The aerodynamic body, rear-wheel ABS, TTB front suspension and all-EFI engine range continued; no major 1989 body redesign is supported by current evidence. [1]
E4OD timing disputed
A transmission reference dates E4OD introduction to 1989, while generation summaries often describe the C6-to-overdrive phase-out as a 1990 change. Both descriptions remain visible. [1] [2]

Models and trims

Base, XL, XLT and Eddie Bauer
The established trim ladder continued. Authenticate original package identity through certification labels, paint/trim codes and paperwork. [1] [3]

Engines and transmissions

4.9-liter EFI inline six
The standard 300 six is commonly listed at 145 hp and 265 lb-ft SAE net. [4]
5.0-liter EFI V8
The optional 302 is commonly listed at 185 hp and 270 lb-ft. [4]
5.8-liter EFI V8
The optional 351W H.O. is listed at 210 hp and 315 lb-ft by a consistent secondary database. [4]

Capability and specifications

Production disputed
Published totals are 69,470 and 66,730. Both exceed the other fourth-generation years in the same sources, but neither has an accessible Ford production report. [1] [5]
Chassis
Dana 44 Twin Traction Beam front suspension and Ford 8.8-inch rear axle continued. [1] [4]

Colors and interiors

Factory finish gap
A complete 1989 Bronco color list is not yet verified. Use certification-label codes and factory literature rather than restored appearance. [3]

Options and packages

Transmission identification
Manual, AOD, C6 and E4OD-era descriptions overlap in secondary summaries. Identify the transmission from its case, tag, controls and build documentation. [2]

Safety and recalls

Rear ABS and driveline inspection
Rear-wheel ABS is not four-wheel ABS. Inspect warning operation, brakes, EFI, transmission, TTB, steering, roof seals, tires, wiring and corrosion. [1]

Owner and buyer notes

Do not buy transmission parts by year alone
The disputed transition timing makes component identification essential before ordering electronics, seals or service parts. [2]

Stories from this year

The peak is clear even if the total is not
The sources disagree by 2,740 units, yet each independently places 1989 above every other fourth-generation year—a useful conclusion with an unresolved exact number. [1] [5]
