What happens if you don’t change rear differential fluid?
Most differentials need a fluid change at about 50,000 miles.
If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail.
If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident..
What fluid goes in a rear differential?
Every front or rear axle is filled with a special oil (also called differential fluid, or gear oil) that takes care of this. The differential fluid lubricates the gears, bearings and other internal parts, and provides cooling to these components as well.
How much does a differential fluid change cost?
When changing the differential fluid, the overall differential fluid change cost averages between $80-$150 for the rear and $70 to $130 for the front change, coming in at a total price of between $150-$280 for the differential fluid change cost.
What does a bad rear differential sound like?
Overly worn out bearings tend to make a howling noise when they do not properly support the gears. Rumbling while turning, on the other hand, is a sign of bad wheel bearings. … This rear differential noise is described as a heavy clicking type of sound which occurs every eight feet or so.

Not quite as often, but at regular intervals nonetheless.
Can you drive without rear differential?
A rear wheel drive can drive without a rear differential, but as both back wheels have to rotate at the same speed, there will be tyre scrub, causing rapid tyre wear and sometimes accelerated mechanical wear and even damage. … You just gas it and turn, both wheels spin, the rear end of the car kicks out and you turn.
What are the symptoms of low differential fluid?
Differential or transmission are whining If the gear oil runs low, or becomes excessively dirty, it can cause the gears to whine or howl as they turn. The whining or howling is caused by lack of lubrication and may increase in volume as vehicle speed increases.
