Lakeland Highlands is home to 12,187 people (2020), an unincorporated community in south Lakeland between the city limits and Mulberry, next door to Medulla. On one side is Lakeland’s distribution economy; on the other is Mulberry’s phosphate economy. The truck routes that link them, SR 37 and the Polk Parkway, run right past the community. RDI Power does not have a shop in Lakeland Highlands. When a diesel stops nearby, a technician comes out from our Brooksville shop with scan tools, test gear and parts.
Breakdown spots on SR 37 and the Polk Parkway near Lakeland Highlands
The Polk Parkway near SR 37 is one of the busiest truck roads in the county: the Polk Transportation Planning Organization puts it at 6,464 trucks a day, behind only I-4 among the roads it listed. SR 37, Florida Avenue, is Lakeland’s main north to south road and the main way south to Mulberry; in FDOT’s 2025 counts, trucks make up 7.3% of its traffic near Lakeland Highlands.
On the parkway, a technician needs the direction and the nearest interchange. On SR 37 or CR 37A, the nearest cross road or a business you can see works best. If the truck stopped on a ramp, say which one.
Lakeland Highlands repairs a technician can finish on site
A truck that will not move is often one failed part away from moving again. On a Lakeland Highlands call, the technician might find:
- An air dryer or governor problem that keeps a tractor from building pressure
- A snapped serpentine belt that took the water pump and alternator drive with it, which means a new belt and an inspection of what it drove
- A DEF sensor or pump fault that put the engine into a reduced-power mode
- Corroded battery cables or a failed ground strap on a pickup that only clicks
- A leaking coolant hose at a reachable clamp
Each of those can usually be tested and fixed without a tow. The scan comes first and the parts second, and every visit ends with a digital vehicle inspection, photos and notes included, so the person paying for the repair sees what was wrong.
Contractor trucks at Lakeland Highlands job sites
If your truck is stuck at a job site in or around Lakeland Highlands, the technician can come to it, as long as there is a safe place to work. That means firm, reasonably level ground, enough room to walk all the way around the truck, and space for the service truck to park beside it. A graded pad or a paved lot is ideal; loose fill or a muddy lot after rain is not. Tell us how to reach the site, whether a gate or a site contact is involved, and where on the site the truck sits. Leave the keys with someone on site if you cannot stay with the truck. If the truck is somewhere other than a site, call anyway and we will talk through the options.
Lakeland Highlands repairs that belong on a lift
Some faults only show themselves once the scan is done: a dropped valve, a transmission that has lost a clutch pack, an internal coolant leak. Those jobs need a lift and a clean bay. The technician lays out what failed, and we plan the move to Brooksville with you, including timing and transport. The findings from the roadside go with the truck. Repairs carry the 3-year / 36,000-mile RDI Power labor warranty either way.
