Sorry. I have 7 miles on the new gears. Just finished this morning. I have done a half dozen sets. I am breaking them in correctly. Short trips, cool down periods etc. I made a solid spacer for the front axle.
The oem rear pinion was burned. 2500 miles on the odometer. Bearing was badly scored. Pinion had oil burned onto it. Fluid was nasty. Front was fine. When I checked the stock rear pinion preload it was <5 inlbs. I think that was the problem. I reused the front bearings and set the back lash at .008, had a perfect pattern, and set the pinion preload at 10inlbs I think on used bearings. On the rear I got backlash to 10, had a really nice drive pattern, coast patter was large and round but slightly outside. Pinion preload set to 30inlbs.
I expect it to be all good but will probably do a gear oil change at 500 miles and check the magnet on the drain plug and the color of the fluid.
