All new gear sets require a break-in period to prevent damage from overheating. Any overloading or over-heating will cause the gear oil to break down and cause undue stress to the ring & pinion gears.

How long does it take to break in new gears?

At Currie, we recommend the initial break-in to start by driving normally for 15-20 minutes (no bun outs, hard starts, or highway driving), then letting the vehicle rest for 30-minutes, never going over 50 miles without letting it cool. Towing and high speeds should also be avoided until after break-in (300-500 miles).

How long does it take to break in a differential?

On initial run, drive lightly for 15 to 20 minutes then stop to allow differential to cool completely for 20 to 25 minutes. Avoid towing and heavy acceleration, as well as vary speeds every 5 to 10 minutes while driving on highways.

How do diffs break?

By putting too much stress on the new car, we mean driving too fast (more than 50 mph) for long periods of time or by towing or hauling another object, such as an RV or a boat. This can cause your differential to overheat and start to break down.

Do you need to break in ring and pinion?

ALL new ring & pinion gear sets must be properly broken in to prevent damage & premature failure. Improper gear break-in procedures may cause overloading and overheating of the ring and pinion gears as well as break down of the gear oil.

How can a rear differential break?

The most common cause of a bad differential is lack of oil, which could result in grinding at high speed, cause the carrier to break, or in most cases, block the rear wheels.

How do you drive after Regearing?

Drive the vehicle lightly for the first 15 to 20 miles and stop. Let the differential cool before proceeding. Avoid heavy acceleration for the first 100 miles. Drive the vehicle at least 500 miles before towing to retain the gears’ warranty.

What causes the rear differential to break?

The most common cause of a bad differential is lack of oil, which could result in grinding at high speed, cause the carrier to break, or in most cases, block the rear wheels. It often happens when you have a worn-out differential seal or a cracked housing which could cause oil leaks.

Why does a diff break?

Lack of Oil: The most common cause of a bad differential is lack of oil, which could result in grinding at high speed, cause the carrier to break, or in most cases, block the rear wheels. Low differential fluid or lack of oil can occur as a result of several reasons.

How do you break in 4×4 gears?

Break in new gears as follows: Insure axle is filled with high quality hypoid gear lubricant, minimum GL5 rating, and any required additive. Drive the vehicle under light load for 20 miles. Stop and let the differential cool completely, at least 30-60 minutes.

How far can I Drive after installing a new gearbox?

• Drive conservatively and do not drive more than 50 miles at a time without allowing a cool cycle during the first 500 miles following installation. • After completing initial break-in, change gear oil at 500 miles. Small metal particles are normal and gear oil will typically be black.

Why are the Gears of a car’s gears treated?

Next, the gears are heat treated for added durability to endure the harsh environments of a daily-driven vehicle. Finally, they are lapped to give the mating surface a smooth finish to reduce friction that can lead to noise and excessive wear.
