At DMA Automotive, we specialize in drivetrain repair in Duluth, GA, helping you stay safe, in control, and cruising confidently on every road.

Understanding the Drivetrain: What It Does and Why It Matters
Your drivetrain is the middleman between your engine and your wheels. It takes all the power your engine produces and delivers it to the tires so your vehicle can move. It includes several key components:
- Transmission
- Driveshaft
- Axles
- Differential
- Transfer case (for AWD/4WD vehicles)
If any of these parts gets out of whack, you could experience anything from sluggish acceleration to clunking noises, vibration, or even loss of traction.
Common Signs You Need Drivetrain Repair
Your drivetrain components take a lot of wear over time. Here’s how you’ll know when it’s time to have them looked at:
- Clunking or clicking sounds when shifting or turning
- Vibration while driving, especially at higher speeds
- Uneven tire wear, often caused by differential or axle issues
- Grease leaking near your wheels (often from a torn CV boot)
- Delayed response when accelerating
- Vehicle pulling to one side, particularly during acceleration
- Burning smells, which can indicate overheating or fluid breakdown
Notice anything weird? Don’t wait. DMA Automotive is here to get your drivetrain back in shape before it leads to bigger, more expensive issues.
What’s Involved in a Drivetrain Inspection
When you bring your car to DMA Automotive for drivetrain issues, we don’t guess. We diagnose. Our techs use advanced tools and years of experience to pinpoint the problem accurately and efficiently.
Here’s what we typically check:
- Driveshaft condition and alignment
- CV joints and boots
- U-joints for signs of wear or looseness
- Differential fluid levels and condition
- Axle integrity
- Mounting hardware and bushings
- Transfer case operation (for AWD/4WD vehicles)
From subtle noises to full-on performance issues, we go beyond the basics to identify the root cause of the problem.
Differential Repair Services
Your differential helps your wheels rotate at different speeds, which is important when turning corners. Without it, your tires would drag and skip, putting a serious strain on your axles and suspension.
At DMA Automotive, we service all types of differentials:
- Open differentials
- Limited-slip differentials
- Locking differentials
- Front, center, and rear configurations
Our differential services include:
- Fluid checks and top-offs
- Fluid flush and replacement (recommended every 30k- 60k miles)
- Leak repair
- Bearing replacement
- Gear inspection and adjustment
We also offer custom differential upgrades and setups for performance vehicles, off-road builds, and towing applications.
Driveshaft Repair and Maintenance
The driveshaft is like the bridge between your transmission and your axles. When it’s damaged or worn, you might hear a thumping sound or feel a wobble under your seat.
We handle all things driveshaft:
- Shaft balancing
- U-joint replacement
- Slip yoke servicing
- Shaft alignment and inspection
- Custom driveshaft fabrication (for lifted or performance vehicles)
Don’t ignore driveshaft issues—they can quickly escalate and put stress on other drivetrain components.
Fluid Service for Long-Term Protection
Fluids are your vehicle’s lifeblood. Old, dirty, or low differential fluid can lead to grinding gears, corrosion, and overheating. At DMA Automotive, we offer complete fluid service options for your drivetrain, including:
- Differential fluid flush and refill
- Transfer case fluid service
- Transmission fluid inspection and replacement
We use premium-grade fluids that meet or exceed your manufacturer’s specifications, keeping your drivetrain protected and your vehicle shifting like it should.
