Break In Period for New Factory Gears?
I'm expecting my new '14 JkU any day now. I started gathering the after market parts when I ordered the the Jeep last month. I now have a basement full of lift parts, front driveshaft, wheels, 35" tires, and other minor add ons. I currently have an '08 JKU that I purchased used and stock. I immediately started the mod process with that one but it had 20,000 miles on it. Is there any reason that I should wait for some type of break in period with the new Jeep before adding the lift and tires? I had 488's installed on the 08 and I know there was a break in period for that. I never heard of a factory gear break in period though. The '14 is an auto with 373's so I'm going to give that a shot before making any decisions to re-gear. Thanks
New vehicles don't seem to be hurt by the lack of a complicated break-in procedure.
I don't see why you can't start modifying immediately. Just be easy on the JK for a little while.
This is from the 2014 Owner's Manual:
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 500 miles (800 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detrimental
and should be avoided. Trailer tow is not recommended
during break in period.
