Been there.


Really? Have you done anything to it?
New ring gear and pinion. This is a common problem in truck rear ends if the gears were not set up correctly or do not wear in correctly when breaking in.

Interesting, didn't know there were a break in procedure for the rear end.

If From incorrect seating, sounds like it can be fixed by readjusting with shims?

When you replaced the ring and pinion, did you kept the same gearing?

Can You also throw us a link of where you purchased?

Would like to do more research about this if there's any mechanical adverse effects left alone or ignored for x amount of miles

That thing may whine forever---my last DP whined in the rear end for 80,000 mi while I had it. Now if it starts to chatter it won't be that much longer till it breaks.

Change out your trans fluid, diff, transfer case.
Check trans and engine mounting bolts.
Check u joints and drive shaft.

IME, once a ring and pinion start whining, unfortunately, it's usually there to stay. The ring and pinion gears are the most highly loaded gear set in the drive train. There is no break in period, BUT, if they are initially set up improperly, they "wear in" very quickly and start to make noise. The noise (and the ring and pinion) may last a normal lifetime (just annoying really) or it may quickly get worse and self destruct. They question to answer is, . . . . . . . "Do you feel lucky?"

Any good parts store can get you a ring and pinion set.

Getting the gears is not a issue. But very few shops are trained or equipped to set the clearance.

Most manufacturers tell you not to tow for the first 500 miles or so. Why do you think that is?
