1995 P30 Differential Problems; Large Shavings

Check wheel bearings also. I had a P30 & the wife complained of a low tone howl. I could never hear it. I had it checked by a truck manchanic who said all ok. She kept complaining until the driver side rear axle sawed itself off at the wheel. The only thing that kept the duel wheels on the rig was the brake assembly. Completely destroyed the entire axle housing. $6000. P30 chassis are notorious for overloading the rear axles.
