4B Diesel Services

4B Diesel Services operates as a mobile truck repair provider serving Manor, Austin, and the greater Travis County corridor from a facility at 1024 Industrial Blvd. The shop holds a 4.7-star average across 102 verified customer reviews, reflecting consistent execution across DOT inspections, diesel engine diagnostics, and emergency roadside calls. Founded in 2014, the business maintains a fleet of mobile service units capable of performing repairs at customer locations, reducing downtime for fleet operators and independent truck owners alike. Weekly hours run Monday through Friday 8AM to 5:30PM, with 24/7 emergency hotline coverage for stranded vehicles.

What distinguishes 4B Diesel from conventional repair shops is their in-house hydraulic hose fabrication capacity, allowing same-day custom hose replacements rather than waiting for third-party suppliers. Their technician roster includes Nick and Adam, both referenced across multiple five-star reviews for addressing oil leak issues and completing repairs that prior shops could not resolve. The shop performs EXPRESS LUBE services alongside major diagnostics, and offers ECM tuning for performance applications, a niche capability few regional providers match. Fleet managers contract the mobile units for on-site preventive maintenance, keeping commercial vehicles operational without routing them to a centralized shop.

Reviewers detailed specific scenarios worth noting. Roy Watan described a front axle hub replacement completed in under 45 minutes after a 15-minute inspection. Cole Hurst praised technician Ryan for arriving on a permitted route with an oversized load during non-standard hours. Patrick Mackenzie Jr noted the shop declined replacing parts that did not warrant replacement, a transparency practice two reviewers specifically mentioned. Negative feedback centered on a single instance of post-service quality oversight, while positive reviews emphasized the team's willingness to address additional concerns during single visits.
