1978 Toyota Corolla Service and Repair Manual

Toyota sold the 1978 Corolla in fifteen trim-and-body combinations: a coupe, a hatchback, two- and four-door sedans and a wagon, most of them available with either a standard or an automatic transmission, across Base, Custom and SR5 grades. Those builds do not share one set of numbers, so this service and repair manual is tied to the 1978 model year and to the trim you actually own rather than to an adjacent year that looks the same in the driveway.

Known issues on the 1978 Corolla. One recall is on federal record for this model year, and it concerns the steering gear box. On the affected cars the lock nut may not have been tightened enough on the steering gear box worm gear bearing and adjuster, and the worm gear adjuster can consequently work loose. Toyota has issued 3 technical service bulletins for the 1978 Corolla.

Whether the job is checking that steering gear box adjuster and its lock nut, a transmission-specific service on a standard or automatic car, or a routine interval on an SR5 hatchback, the work stays on Toyota's own procedure and specification for the 1978 Corolla.
