1st Lube Change After Gear Swap I was just curious how everyone elses gear oil looked when they did their first gear oil change after a gear swap. I put in a Auburn High Perf posi and motive 4.10's in back in March. I decided to change the gear oil at 400 miles and it was gray like it was full of metal. I checked the gear and it looks good. The posi looks fine and I checked the wear pattern and backlash. All looks good. Could this just be normal break in wear and tear.

yup. its dust from the clutches and tiny particals from the bearings, the magnet picks up most of the larger shavings. If you have an aftermarket cover its a good idea to epoxy a magnet somewhere in the housing or cover just for that reason, flush it out with brake cleaner, wash off magnet and cover. scrape the gasket surface clean and dry and reinstall with a new gasket, torque the bolts down in a star pattern. refill and your good to go. use teflon tape on the jack screws on the aftermarket cover if they leak.
