Hi!
My car (190E 2.3 Avantgarde), has a slight whine in the differential when letting off the pedal and then just touching it. All minor parts inside has been changed, but the sound is more or less still there. Now a new diff or a used one costs a lot, so I just wondered if there is something more I could do? Is there a special good oil or something that would help? Please help, the sound drives me nuts!!!

Is this the kind of noise that happens just when it's between pulling and coasting? That just usually means there is just a little too much play in it. If it's not too bad and has plenty of the right kind of lubricant it could go for years like that. The alternative is spending bucks to fix it. I don't think any kind of additive except maybe sawdust will damp the sound. Turn up the radio.

A friend had a whine in his Volvo diff and he put Amsoil 85w140 Gear oil in and apparently she shut right up.

I have been down this road. Try the synthetic gear oil and see what happens.. I dont think any oil will undo all that wear and tear. The bearings do go bad on those things, and any improper repair will accelarate the weak parts. After I screwed up my existing diff by repalcing the seals and over torquing the front seal/flange nut(the torq spec in the CD was for a new crush sleeve that separates the bearings on the pinion), I tryed a used one. For under $200 it works but it is noisy.

Save some time and headache and get a rebuilt one. Its easy to put in.

Sounds like excessive ring and pinion clearance. What minor?? parts are you referring to?? If the ring and pinion were disturbed, then whoever worked on it did not set it up properly. You need to go back and get it put right. You need a good tech to set up rear ends properly..
