Exclamation I NEED INPUT!!! Rear End Differential F*cked, Bearing Sound, Rear End Replacement...

Morning!!!


Well... After not noticing a small leak from the inputshaft seal, I more-or-less leaked out all my gearoil with NO clue sometime in the last few weeks...


Last night:


At about 75mph, a shudder, loud metalic "pop" and not a VERY obvious whine that anybody with any auto notice would automatically think is a bearing failure...

I BELIEVE its the bearing wear the shaft comes into the pumpkin before the gears.

BUT, after making several phone calls this morning it appears it is going to be cheaper to replace the entire rear end...


1. Is this true? Does anybody have any thoughts "yay", "nay" or otherwise?

2. I need the specifics on the rear end for my Commander. I have a 2006, and it's the Limited with 4.7l V8...
As much information in order to find a replacement would be helpful!

3. Any thoughts, tips, tricks on swapping out the rear end???


ANY help anybody can provide on this would be MUCH appeciated!!!


Thanks!

The shops are probably assuming there is more wrong than just the one bearing. More likely the gears and all bearing and seals are chewed up from running dry. In this case its less labor to just swap in a working rear end. Maybe you got extremely lucky, but fixing it piece-wise will kill you on labor.

Thanks for the reply!!!

Well, it's at the Dealership now... They said worst case scenrio, $2200 to rebuild the rear end with all new parts. The price is all inclusive.

When I tried to "shop around" the junkyards, the best I could come up with in this region was a rear end with 105k miles, for $1600, and it's a week away!

... Needless to say, I chose the extra few hundred dollars option with a year warrenty, and all new parts. Apparently Dana rear-end for a Commander are at a premium in the area right now I guess.

The dealership is getting an estimate on "how bad" as we speak, and then I'll know how bad the damage is. I'm hoping for thr best... BUT it's not looking great.
