A failed differential is one of the most expensive driveline repairs. Replacement at a shop runs $1,200-$3,800. A rebuild (bearings, gears, fluid) can be cheaper at $900-$2,200 if the housing is intact.
Most drivers pay $1,800 to $2,800 at an independent shop for a typical RWD or AWD differential. HD truck and luxury differentials can exceed $5,000.
If the case is sound, a bearings/gears rebuild runs $900-$2,200. A whole-unit swap costs more but takes less shop time.
AWD vehicles have front and rear differentials plus a transfer case - any can fail.
LSD and locking differentials cost 1.5-2.5x more than open differentials.
Setting ring-and-pinion backlash and pinion preload is precision work and adds shop time.
Most differentials need specific fluid and friction modifier - $30-$80 extra.
Often have to come out for differential access - inspect them while in there.

For most owners with basic tools and a safe place to work, this is within reach if the difficulty label says "Easy" or "Moderate." Hard and Expert jobs mean special tools, safety risk, or scan-tool requirements - usually worth paying a shop for. If you have never bled brakes, used a press, or worked under a vehicle on jack stands, start with a smaller job first.

A whining or humming noise that changes with speed, clunks on takeoff, gear-oil leaks at the diff cover, or visible metal on the magnetic plug.
Short distance, low speed only. A grenading differential can lock the axle and destroy the driveshaft and axles too.
If the case and ring/pinion are sound, rebuild for cost. If gears are chewed up, a complete unit swap is faster.
You have a transfer case and two differentials. Any of the three can fail and each is a separate component.
Every 30,000-60,000 miles for severe use, 60,000-100,000 for normal. Always change after wading through water.
Yes - usually 500 miles of moderate driving and an early fluid change after the first 500 miles.
