Triple J Diagnostics specializes in enclosed, cargo, and semitrailer repair — electrical, brakes, axles, and frame work — across most of Florida, with a fast, honest diagnosis every time and a technician who shows up when he says he will.
Every job starts with a real diagnosis, so you're only paying to fix what's actually wrong.
Recurring scheduled maintenance to catch small issues before they turn into a breakdown.
Lights out, brakes not engaging, battery drain — traced and fixed at the source, not just patched.
Brake controllers, magnets, bearings, and axle alignment for enclosed and cargo trailers.
Weld repairs, cross-member damage, and structural fixes to keep the box and frame road-worthy.
Wear diagnosis, bearing service, and replacements before a blowout turns into a bigger problem.
Pre-trip and post-incident inspections that catch what's failing before it strands you.
We come to the trailer — home, job site, or lot — across most of Florida.
Landing gear, suspension, air lines, and 5th-wheel connection points on dry vans and flatbeds.
Solar panel installation and wiring to keep trailer batteries charged on the road.
Regular routes and repeat customers around these cities — and most points between.
You get a clear answer on what's wrong before any work starts — no guesswork billed by the hour.
Mobile service means the repair comes to you — scheduled and confirmed, not a vague window.
Every repair is done to hold up under real towing conditions, not just pass a quick look.
