How difficult is it to replace a rear differential?

Bearing replacement on your rear differentials can take up to five hours and require special tools to push them in and out. Gear Replacement. Chipped and worn down teeth on your differential gears also cause the noises you hear when these parts go bad.

Is it hard to change diff gears?

Diff gears might seem incredibly complicated, but they’re one of the simplest components in any 4×4 and are surprisingly easy to get right. In their basic form they’re used to redirect the drive coming from your engine and transmission through to your wheels.

Is it hard to change a pinion seal?

Fortunately, replacing a pinion seal isn’t a difficult task and there are a variety of methods to successfully accomplish that. Like GM, we, too, must caution that the relationship of the pinion gear, pinion flange, and retaining nut must be exactly maintained so that pinion bearing preload isn’t altered.

Can I change my rear gear ratio?

You can change the axle ratio, and you can do it rather easily. Quite a few members here have gone from one ratio to the next. People with 3.21 and 3.55s are going up to 3.92 and even sometimes 4.10. A lot of the 4×4 trucks you see here with lifts and larger tires have gone with 4.10 or 4.56.

How much does it cost to re differential a gear?

Re: How much $$ to re-gear diffs Labor should be around $250/axle. That’s based on a 3-hour job per axle at a shop rate of $75/hour and rounded-up for sales tax. Parts kits (“Master” parts kits, including all bearings, races, ring bolts and shims) are about $125/axle.

How often should I change my rear differential?

The best thing you can do to preserve the life of your rear-diff is to change the differential fluid every 30,000-50,000 miles. Additionally, you should have your drivetrain inspected annually. Doing so will ensure that any repairs are simple, rather than needing a full differential replacement.

What causes a rear differential to go bad?

A limited slip differential is a type of differential that limits the independency of the driven wheels that are on the same axle. So, while open differential sends power to the wheel with the least amount resistance, LSD distributes the power and torque between the wheels and the car is able to move while the one with open diff would be stuck.

Do you have to replace rear diff cover?

Most rear-diff covers are rubber or silicone, which can wear and dry out over time. To prevent them from leaking, you’ll have to have them replaced. Thankfully, this is an easy repair that shouldn’t take more than an hour. There are two bearings in a differential, the one for the pinion, and the one for the side.

Why do you need a limited slip differential?

A limited-slip diff acts just like an open one, under normal conditions. However, where a limited-slip diff takes things a step further, is that it can limit the amount of power it sends should a wheel lose traction. Meanings it not only provides better stability but increases safety as well.

How to tell if you have a rear differential problem?

Symptoms of Rear Differential Issues Typically, there are two symptoms you’ll notice when you have a bad differential, or car differential problems: Rear Differential Noise – if you hear howling from the rear of your truck or SUV when you’re driving, it’s possible it’s rear differential noise.

Why does my rear differential make noise when coasting?

Sometimes this issue evolves into experiencing noise during coasting as well. Interestingly sometimes differential noise on acceleration appears not because the teeth are misaligned but because the user got stuck and forced the car to get unstuck.

What does it mean when your rear differential is Howling?

Rear Differential Noise – if you hear howling from the rear of your truck or SUV when you’re driving, it’s possible it’s rear differential noise. It can change in pitch as well as come and go depending on the severity of the issue and load on the diff.
