The GM Service Manual has special instructions to "remove the pinion shaft from the case on vehicles without a locking differential" or "with a locking differential remove the shaft part way and rotate the case until pinion shaft touches the housing".
My question is how do I know if I have a locking differential??
ANY advice or helpful tips would be greatly appreciated!! Thank u in advance!!
I have a 1996 V8 5.7L, 4L60E, 10-bolt, 3.42 gear ratio, & 8.5" rear end (I'm fairly certain on that last part).
