Hotchkis Bushing Removal / Installer Tool - 32101

The Hotchkis GM Upper Trailing Arm Bushing Install and Removal Tool (Part #32101) is a purpose-built specialty tool designed to make bushing service on GM 10-bolt and 12-bolt rear ends clean, controlled, and damage-free. Whether you're a professional shop upgrading a muscle car's suspension or a dedicated backyard builder refreshing an A-Body classic, this tool eliminates the guesswork — and the risk — of pounding bushings in or out with a hammer and drift.

Key Features & Benefits

• Designed for GM 10 & 12-Bolt Rear Ends: Purpose-engineered to fit the specific geometry of upper trailing arm bushing bores found in these common GM axle assemblies — no improvising with generic press adapters required.
• Easy Removal AND Installation: A single tool handles both operations, so you're not hunting for a second adapter set mid-job. Remove worn rubber bushings and press in fresh replacements with the same unit.
• Protects Your Axle Housing: As Hotchkis puts it, "the days of pounding on your freshly powdercoated axle with a sledge hammer are over." A controlled pressing action keeps your housing, trailing arms, and new bushings undamaged throughout the process.
• Professional or DIY Friendly: Hotchkis explicitly describes this as a great addition to both professional and backyard mechanic tool boxes — the design is accessible without sacrificing shop-grade function.
• From the Suspension Specialists: Hotchkis Sport Suspension is a recognized name in GM A-Body and classic muscle car suspension, meaning this tool is designed by engineers who also build the trailing arms and bushings it's meant to service.

• Buick: Century (1978–1981), Regal Base/Limited/Sport/T-Type/Grand National/GNX (1978–1987), Roadmaster Base/Limited/Estate Wagon (1991–1996), Skylark (1964–1972)

Frequently Asked Questions

What rear axle types does the Hotchkis 32101 tool work with?

The Hotchkis 32101 is designed specifically for GM 10-bolt and 12-bolt rear ends. It is built to remove and install upper trailing arm bushings in those axle assemblies and is not designed for other rear axle configurations.

Does this tool handle both removal and installation, or do I need separate tools?

This is a single dual-purpose tool. It handles both the removal of old, worn bushings and the installation of new bushings in GM 10 and 12-bolt upper trailing arm housings — no additional adapter kits needed for basic bushing service on these applications.

What vehicles is this tool compatible with?

The tool covers a wide range of GM vehicles with 10 or 12-bolt rear axles, including various Buick Century, Regal, Roadmaster, and Skylark models, as well as Chevrolet Caprice and Caprice Classic variants spanning roughly the 1964–1996 era. Because the fitment list is extensive, we recommend verifying your specific year, make, model, and submodel against Hotchkis's vehicle selector or contacting us directly.

Is this tool suitable for a DIY install, or is it shop-only equipment?

Hotchkis designed the 32101 to work equally well for professional shops and dedicated backyard mechanics. If you have basic mechanical skills and access to a bench vise or hydraulic press, this tool makes upper trailing arm bushing service significantly more controlled and safer for your axle housing than improvising with a hammer and drift.
