Q:Can a ring and pinion from two different sets be used together?
A:No.Gear sets are lapped at the factory and are a matched set. Attempting to run two different gears together will result in gear noise and eventual failure.
Q:What is the break-in procedure for a new set of gears?
A:All new gear sets require a break-in period to prevent damage from overheating. After driving the first 15 or 20 miles it is best to let the differential cool before proceeding. We recommend at least 500 miles before towing. We also recommend towing for very short distances (less than 15 miles) and letting the differential cool before continuing during the first 45 towing miles. This may seem unnecessary but we have seen many differentials damaged from being loaded before the gear set was broken in. Changing the gear oil after the first 500 miles is also recommend. This will remove any metal particles or phosphorus coating that has come from the new gear set.
Q:I can’t get a good drive pattern on my used gear. What’s wrong?
A:When testing your pattern on a used gear, it is often difficult or impossible to get a good pattern on the drive side of the gear. The reason for this is that through use the drive sides of the gears wear and won’t show you the pattern clearly. The solution is to check the pattern based on the coast side of the gear. In standard rotation front differentials, you will still want to check the drive side of the gear since that is the side which gets the least amount of wear in those applications.
