No, unless the front bearing on the pump wobbles a lot.

This requires you nearly overhaul the entire differential minus the ring and pinion, all bearing must be replaced as the metal from the failed one has damaged the others three bearings and they will fail shortly. This job requires many special tools including a hydraulic press, remove the entire unit and have a shop rebuilt it to save money.

Maybe time for a throttle body cleaning, make sure both the front side and back side are cleaned thoroughly. Also disconnect the battery while doing the cleaning, this will reset the computer and allow it to relearn to the cleaned throttle body.
Do you mean a whining sound? Does the sound change if you turn the wheel to the right or left? If so, it may be a front wheel bearing.
