Peterbilt Repair in Janesville, WI

Keeping Your Peterbilt Running Strong in Janesville, WI

Peterbilt trucks are known for durability and performance, but even well-built equipment needs attention as miles add up. Warning lights, loss of power, steering concerns, brake issues, or uneven tire wear are signs that repairs shouldn’t be delayed. Addressing problems early helps prevent roadside failures and costly secondary damage.

Our shop is designed to handle trucks and trailers efficiently, with large drive-through bays that eliminate wasted time repositioning equipment. From diagnostics and mechanical repairs to alignment-related concerns that impact handling and tire life, each repair is approached with accuracy and consistency.

For situations where a truck can’t make it to the shop, mobile service is available and treated as roadside support. This allows issues to be addressed where the breakdown happens, helping reduce tow costs and extended delays. Block Diesel Repair operates Monday through Friday from 7:00 AM to Midnight, with 24/7 roadside service available when problems happen outside regular hours.

What Makes Us Different

Downtime doesn’t follow a schedule, and neither should your repair support. Block Diesel Repair operates with six fully equipped mobile units, allowing roadside and on-site repairs to be handled quickly across a wide service radius. This is especially valuable when breakdowns occur between terminals, job sites, or along major routes.

Preventive maintenance is also performed on location, helping reduce unexpected failures and extend component life. With more than 400 trailers currently serviced on the road, systems are already in place to support ongoing maintenance without disrupting daily operations.

Inside the facility, six drive-through bays measuring 130 feet wide and 100 feet deep allow trucks and trailers to move straight in and out. One side is dedicated to trailers and the other to trucks, keeping workflow organized and efficient. The largest alignment pit in Wisconsin allows for precise corrections that directly impact tire wear, tracking, and driver comfort.

Industry certifications across major engine, brake, and diagnostic platforms further support consistent, standards-based repairs.
