All the gear sets I've bought over the years, the instructions are to drive them easy. keep the first couple of drives short, no heavy throttle, cool off. Repeat.

After a couple hundred miles, I'd change the lube, then have at it full power at will.


From Richmond's web site:

BREAK IN
A new ring and pinion installation, especially a high numeric ratio with new bearings, can cause an excessive heat buildup in the rear end and cause softening of the gear teeth and bearings if a break in is not performed.
Street vehicles should be driven at normal street driving speed for approximately 10 miles, then stop and let cool for 30 minutes. Do this 2 to 3 times. Towing vehicles need approximately 200-300 miles of normal street driving before being used for towing.
On circle track race cars make approximately 6 to 8 laps at slow speed, then let cool for 30 minutes. Make 6 to 8 more laps at slow speed, then 2 to 3 laps at full speed, the let cool again for 30 minutes.
Drag cars need only an initial run-in since they are driven short distances and heat is not normally a problem with proper lube and backlash allowance.
NOTE: If after the above break in is performed, overheating of the rear end is suspected, repeat the final portion of the break in procedures.

Man, I went with synthetic oil in the dif..is the oil change necessary after break in? And so i basically need to just drive 10 miles and pull over for 30 min 3 times and its broken in?
