I replaced the wheel hubs and rear axle wheel bearings so there is nothing between the discs and the plates but thanks for the suggestion.
What I noticed though is that the pinion seal of the Rear Diff is leaking and there is humming noise coming from the rear diff from 40mph and above so I wonder if the squeaky noise at very low speed comes also from the rear diff and turns itself into a loud humming noise at higher speed.
I already bought the complete rebuilt kit for Dana 44 so I am debating if it's possible to check that the pinion outer bearing is damaged by just removing the Prop Shaft and the seal or should I give the lot to do to a pro ?
I know the latest is the safest option but it's also the dearest one.
