Wavetrac Differential for 02M/02Q 6MT 4WD

Simply put - Wavetrac is the only gear diff on the market that does not lose all drive when one axle is unloaded. Axles become unloaded in aggressive driving, track cornering, extremely slick surfaces, etc. It happens more than most people realise.

We won’t go into torque bias ratios or the concept of how torque biasing diffs work at this point. Let’s get to how the Wavetrac affects performance:

For example, you have a conventional gear diff (OEM, Quaife, MF, OBX, Truetrac, Torsen, etc.), you're on a race track for a track day and during cornering your inside wheel bumps over the curbing. This is normal for track driving. The issue is that for the brief moments your inside tire becomes unloaded when bouncing over curbs, your other wheel is not getting drive - is not putting power down. Gear diffs need load on both axles in order to function. The result on a track (or during aggressive driving) is that there are many times when a normal gear diff supplies only intermittent power to the gripping wheel.

Now, same track with Wavetrac: the patented cam device in the Wavetrac prevents loss of drive when that inside wheel is unloaded. The device is able to generate a load inside the diff (to replace the lost load as it happens) that can then be biased to the gripping wheel - in the end making more consistent power delivery through a corner. That makes the car more predictable, and faster overall.

Other benefits:

• Patented Carbon Fibre Bias Plate for the pinions. All other gear type LSDs run the pinions on the housing, meaning the friction from 0 miles is different to 100 miles, thus effectiveness is reduced over the life of the diff. With the Wavetrac performance is consistent with the Carbon Fibre bias plates!
• Patented Wave Profile eliminates the effect of a near to and zero load condition drive ability issues found in all other gear type ATB LSDs.
• ARP Bolts used throughout for superior faster reliability. 
• 9310 steel gears run in billet or forged steel bodies. 
• Lifetime, transferable warranty
• Manufactured & Designed in the USA

1. Installation Issues

• Incorrect Fitment: The most common problem occurs when the wrong version of the differential is used for a particular vehicle. The 02M/02Q gearbox comes in multiple variations, and the front differential housing must be the right match for the LSD.

2. Excessive Noise

• Noises During Break-In: Some users report a clicking or clunking sound after installation, which is typically normal in helical LSDs (like Wavetrac’s). This sound is caused by the gears engaging and disengaging during normal driving conditions.

3. Overheating and Lubrication Problems

• Heat Buildup: If the differential is not properly maintained, or if you're driving in aggressive conditions (e.g., on a track or during spirited driving), the LSD can overheat. This may cause a loss of performance or eventual failure.

4. Premature Wear or Damage

• Aggressive Driving: If the vehicle is used for track racing, drag racing, or in conditions with heavy acceleration and braking, it can place additional stress on the Wavetrac LSD. This can lead to premature wear of the internal components.

5. Misalignment or Excessive Play

• Improper Alignment: During installation, if the differential is not properly aligned with the differential housing, it can lead to uneven torque transfer or excessive play in the differential. This can cause an unstable or unpredictable driving experience.

6. Fitment Issues with Transfer Case

• Haldex/Quattro Transfer Case Compatibility: The 02M/02Q AWD systems typically feature a Haldex or Quattro transfer case, and the Wavetrac LSD needs to be compatible with the front differential housing. Some versions of the gearbox may have slight variations in housing design or tooth count, leading to potential fitment issues.
