I upgraded my differential gears about 500 miles ago to 4.88 from 3.21. I have driven it as recommended by the mechanic but am curious when you guys change the gear oil after a gear swap. Do you do the break in then change or just go into the normal maintenance pattern from the start. Yes I have searched the forum for the answer and can't seem to find the answer.
Exactly. While establishing a wear pattern they will contaminant the oil with fine metal shavings. Leaving the break in oil in for a long period of time is a very bad idea and has lead to bearing failure in more then one diff that I have seen.
I'm here to participate. I didnt come all this way just to watch.
