Installation Notes and Tips

Verify thread direction, thread diameter, and position before installation. TA5379 is a non-adjustable straight tie rod end, so alignment should be checked after replacement to confirm steering geometry and toe settings. Confirm rear outer placement on the vehicle and compare the removed part to the new component before assembly. Delphi TA5379 is commonly selected for rear outer service on Buick LeSabre, Cadillac DeVille, and Pontiac Bonneville applications.

Quality Assurance

Delphi uses OE-based engineering methods and durability testing for its steering portfolio, including temperature exposure below -40 degrees C and above 120 degrees C, plus extended salt-spray testing. Those validation steps support consistent aftermarket replacement quality for Delphi TA5379 and help align the part with OE fit and material expectations.
