1. Differential Housing
Inspection and Cleaning:Open the differential to check for cracks or damage. Clean out any old fluid and debris.Resurfacing:If there are signs of wear, a machine shop may resurface or repair the housing.Reassembly:Ensure proper torque specifications on housing bolts; replace any damaged hardware.
2. Clutch Plates and Friction Discs
Disassembly:Carefully remove the clutch stack, noting the order of plates and discs.Inspection:Check for burnt surfaces or warping; replace if excessively worn.Reassembly:Reinstall plates and discs in correct sequence, applying fresh gear oil or limited-slip additive to friction surfaces.
3. Preload Springs or Belleville Spring
Removal:Release or unbolt retaining components to remove the spring assembly.Inspection:Check for cracks, deformations, or uneven wear; replace if necessary.Installation:Install and compress the springs uniformly, ensuring correct preload is applied to the clutch pack.
4. Side and Pinion Gears
Removal:Extract gears carefully, taking note of any shims or spacers.Cleaning:Remove metal shavings and old lubricant from gear teeth.Reassembly:Reinstall gears in correct orientation; measure backlash and gear tooth contact patterns; adjust with shims if needed.
5. Bearings
Inspection:Check bearings for rough spots, discoloration, or excessive play.Removal and Replacement:Press out old bearings and press in new ones using the correct tools.Lubrication:Apply recommended lubricant before reassembly; ensure bearings spin freely.
6. Seals
Diagnosis:Look for leaks or seepage around axle ends or input/output shafts.Removal:Carefully pry out old seals to avoid damaging the housing.Installation:Coat new seals with a thin film of lubricant and press them in evenly; ensure proper alignment.
7. Limited-Slip Additives and Gear Oil
Drain and Fill:Drain old fluid and inspect it for metal particles or discoloration.Fluid Selection:Use the correct grade of gear oil with the required limited-slip additive.Refill:Ensure fluid is at the proper level; check for leaks and road test the vehicle.

Clutch Pack (Friction Discs and Plates)
Signs of failure:
- Slipping or reduced power transfer to the wheels
- Excessive chattering or jerking during acceleration
- Burning smell from overheated friction material
- Metal shavings or discoloration in the differential fluid
Pressure Plate
Signs of failure:
- Difficulty engaging power smoothly under load
- Vibrations or rattling when the differential is under stress
- Visible warping or cracks in the pressure plate
- Uneven or excessive wear on the contact surface
Side Gears
Signs of failure:
- Rough or noisy operation when turning
- Excessive play or looseness noted during inspection
- Uneven wear patterns on gear teeth
- Whining or grinding sounds, especially on corners
Spider Gears
Signs of failure:
- Clunking or banging noises when changing direction
- Metal fragments in differential fluid
- Difficulty maintaining consistent wheel speed in corners
- Noticeable damage or chips on gear teeth
Preload Springs
Signs of failure:
- Reduced clutch pack pressure manifesting as slipping
- Decreased overall differential locking effect
- Broken or compressed springs visible upon inspection
- Vibrations and poor handling under acceleration
Differential Housing
Signs of failure:
- Cracks or leaks around the casing
- Excessive external wear or impact damage
- Ongoing fluid leaks leading to low lubrication
- Frequent overheating or burnt fluid due to compromised protection
Differential Fluid
Signs of failure:
- Discoloration or burnt smell indicating high temperatures
- Contamination with metal shavings or debris
- Grinding or whining sounds points to inadequate lubrication
- Sluggish or inconsistent power distribution under load
