Car Frame Repair Cost in 2026
$600 – $10,000
Frame repair costs $600 to $1,500 for minor straightening on a frame machine, $1,000–$5,000 for unibody rail or section replacement, and $5,000–$10,000+ for severe structural damage. Insurers total a car when repairs exceed roughly 70–80% of its value — so moderate frame damage on an older car often means a total loss.

Frame repair cost by damage type
| Repair type | Cost (USD) |
|---|---|
| Frame measurement & diagnostic | $100 – $300 |
| Minor frame straightening (frame machine) | $600 – $1,500 |
| Unibody rail / section replacement | $1,000 – $5,000 |

| Severe structural repair | $5,000 – $10,000 |
What affects the price
- Unibody vs body-on-frame — unibody cars are repairable but labor-intensive; truck frames are cheaper to pull but rust sections may need welding.
- Severity and location — damage near suspension mounting points or crumple zones requires more measurement and precision.
- Rust extent — surface rust is cosmetic; rot through frame rails on trucks costs $500–$3,000 to cut out and weld.
- Total-loss threshold — if the estimate exceeds ~70–80% of the car's value, the insurer totals it instead.
- Title branding — repaired structural damage often means a salvage/rebuilt title, cutting resale value 20–40%.
Frequently Asked Questions
Is a car with frame damage always totaled?▾
No — minor straightening ($600–$1,500) is worth doing on a newer car. But on a car worth under $8,000, even moderate frame work usually crosses the insurer's total-loss threshold.
Is a repaired frame safe to drive?▾
When repaired properly on a computerized frame machine and verified by measurement, yes. A poorly repaired frame compromises crash protection — always get post-repair measurements documented.
Can frame rust be repaired?▾
Surface rust: yes, cheaply. Rot-through on frame rails can be cut out and welded with reinforcement plates ($500–$3,000), but widespread rot on a unibody usually isn't economically repairable.
Does insurance cover frame damage?▾
Collision coverage covers accident-related frame damage minus your deductible. Rust is never covered — it's considered maintenance/wear.
