Gearbox and Steering Column Upgrade - Tech

With these parts and a little elbow grease, you'll be ready to steer straight.

If you're cruising an older Chevy Impala and you're rollin' down the strip or the highway, you might notice that the steering's a little sloppy or loose. This is due to normal wear on the rag joints and bearings in the steering column. How do you get back to steering straight? Well, the answer is simple: you can change out your complete steering system with a newer-style setup. You can start off with your steering column and union joints that connect to the gearbox. If you own an older Impala, you should consider upgrading the gearbox, as we did in this tech.

This '63 Impala had several problems with the old slave cylinders, which tend to leak fluid and give you too much unwanted play, so we decided to upgrade the complete system. We started off by swapping out the gearbox with a newer one from ABS (American Braking & Steering), which are sold with either a chrome-plated or stock black finish, depending on your needs. In our case, this chromed-out car received the upgraded gearbox that matched the already chrome-plated undercarriage.

The steering column was upgraded with an Ididit chrome column, which helped tighten up the "feel" when driving. Also tying into this tech were the Borgenson joints and shaft, as well as the Billet Specialties steering wheel and the Rare Parts pitman arm. These new aftermarket products will help your classic steer like a newer vehicle.

If you don't have power steering or if you own a vehicle with an older-style setup, this tech will be perfect for you. Now follow along as Jaime from ABS shows us how to steer straight with less drag.

Here's a sample of the ABS black gearbox that will work for '59-'64 Impalas.
