Do you have to break-in a new differential?
All new gear sets require a break-in period to prevent damage from overheating. Please follow these guidelines to insure proper break-in: After light use for the first 15-20 miles, stop and let the differential cool before proceeding any further.
How long does it take to break-in a new differential?
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.
How many miles does it take to break-in new gears?
Keep the vehicle at speeds below 60 mph for the first 100 miles. I also recommend putting at least 500 miles on the new gear set before heavy use or towing. During the first 45 miles of towing, it helps to go about 15 miles at a time before stopping to let the differential cool for 15 minutes before continuing.
What causes a 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.
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.
Why does a differential break?
Defining Differential Carrier Breaks As the numerical ratio of a gear set increases, the diameter of the pinion gear gets smaller. It becomes more economical at some point to change the carrier deck height, so that the ring gear is thinner, and requires less material.
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.
Do you need to break in ring and pinion?
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.
Can I drive with a broken rear differential?
Technically, you can drive with a bad differential, but it is not wise. The problem may get worse, to the point where it leaves you stranded somewhere. It can also cause damage to other surrounding components. It is smartest and safest not to drive with a bad differential.
Why do I need a break in for my differential?
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. Please follow these guidelines to insure proper break-in:
When to stop for a diff break in?
If you plan to do any towing following the initial 500 miles, then tow for a short distance (about 15 miles) and then stop to let the differential cool for 10-15 mins. Then resume your trip as planned. If you’ve already put in over 1,000 miles on the new differential, then the diff is already broken in. Feel free to tow as normal.
Can you burn out a new car differential?
And no, it’s not by doing burnouts. If you replace a differential on your car, you shouldn’t proceed to drive away immediately as if nothing’s new. Engineering Explained’s Jason Fenske lays out the break-in procedure for a new differential in his latest video.
When to change the oil on a new differential?
If you’ve already put in over 1,000 miles on the new differential, then the diff is already broken in. Feel free to tow as normal. We highly recommend changing the oil after the first 500 miles.
