Remanufactured Differentials in Pinetown – Smooth, Quiet & Long-Lasting Performance
Your differential plays a crucial role in how your vehicle drives, handles corners, and delivers power to the wheels. When it becomes noisy, worn, or fails completely, you need a solution that restores performance without the cost of replacing the entire axle.
At Pinetown Diff & Gearbox (PDG), we specialise in remanufactured differentials that are rebuilt to precise specifications, using upgraded components and strict quality standards. The result is a differential that delivers quiet operation, reliable performance, and long-term durability — all at a more affordable price than buying new.
What Is a Remanufactured Differential?
A remanufactured differential is a complete rebuild of your differential assembly. Instead of simply repairing one component, the entire unit is:
-
Stripped and disassembled
-
Cleaned and inspected for damage
-
Rebuilt with new bearings, shims, seals, and upgraded internals
-
Set to factory-correct preload, backlash, and gear contact pattern
-
Precision-tested for smooth, quiet operation
This is far superior to a “repair only” or “second-hand” differential, where worn components remain untouched and failure is more likely to return.
Benefits of a Remanufactured Differential
1. Quiet, Smooth Driving
A properly remanufactured differential eliminates whining, humming, or grinding.
Your vehicle drives quietly, smoothly, and with consistent power delivery.
2. Improved Reliability
New bearings, new seals, and corrected tolerances greatly reduce the chance of future failure.
The differential becomes more dependable than before.
3. Correct Preload & Backlash Settings
We reset preload, backlash, and gear mesh to exact factory specifications.
This prevents premature wear and ensures maximum gear life.
4. Warranty Backed
All remanufactured differentials include a workmanship warranty, giving you peace of mind and confidence in the rebuild.
5. Cost-Effective Solution
A remanufactured differential is far cheaper than:
-
Buying a brand-new differential
-
Replacing the entire axle assembly
-
Repeated repairs caused by reusing worn old parts
It’s the most economical long-term solution for restoring your vehicle’s driveline.

FAQ’s
What causes differential noise?
Most differential noises come from worn bearings, incorrect backlash, collapsed shims, or low oil levels. A remanufactured differential corrects these issues completely.
How long does a remanufactured gearbox last?
With correct setup and new components, a remanufactured differential can last many years — often longer than an old unserviced OEM unit.
Is a remanufactured differential better than a used one?
Yes. A used differential still contains old bearings and wear points. A remanufactured unit is rebuilt with new components and tested to factory specifications.
What symptoms mean I need differential work?
Common signs include humming noises, whining on acceleration or deceleration, clunking during take-off, vibrations, or oil leaks. We offer free diagnostics to confirm the fault.
How much does a remanufactured differential cost?
Costs vary depending on the vehicle, but it is always cheaper than buying new. We provide upfront pricing and a workmanship warranty on every rebuild.
