QuestionIs it possible for me to check the oil in the rear differential? Or is that something a shop mechanic should do? I'm guessing the rear end at least needs to be up on ramps, the simplicity of the how to do it will answer that? If the answer is more than one sentence, I'll have somebody else do it. No, changing the pressure hasn't made a difference.
Thanks very much for your first reply!

Question -
3 weeks ago began picking up humming/vibrating appearing to come from front driver's side wheel and can be felt through the pedal. 1998 Chevy S-10 4.3 Vortec V6. Attempted repairs: professional mechanic repacked wheel bearings, replaced rotors and pads, rotated tires, replaced loose idler arm. Humming/vibrating begins @ 60mph, peaks at 65 (have to turn up the radio) and originally disappears @ 70+mph, but it seems to be getting worse, now requiring 71-73mph before going away. Mechanic suspects gears wearing down in differential.
Second opinion? Suggestions? (professional mechanic will be doing repairs)

Hi Mike,
Didn't say if that is a four wheel drive.
Be sure to check the "U"joints for looseness.
I assume you have changed the air pressure in the tires to check for tread noise?
Oil in the rear differential checked?
AnswerHi Mike,
I speciffically asked if that's a four wheel drive, and you still haven't said.
As for the rear differential oil checking, in one sentence, yes, you can check it yourself by just sliding under there and remove the little check/fill plug, and see if you can touch oil with your finger.
Reason I want to know about the 4 wheel drive, is thinking about how it gets driven, and if there is any chance something hit the driveshaft and bent it slightly.
And check the "U"joints.
