It’s not too difficult to tell an LSD transmission apart from a non-LSD transmission if you know what to look for. Where the driver side axle enters the transmission, an LSD gear box features a bulge. On a non-LSD transmission, the same region is virtually entirely flat. Additionally, take note of the LSD transmission’s massive driver side axle seal (larger than the passenger side seal). On the non-LSD transmission, the driver side axle seal is substantially smaller (same size as the passenger side seal).
Axles:
Above is the non-LSD axle, and below is the LSD axle. The LSD itself is positioned on the driver’s side of an LSD transmission and protrudes outward by a few inches. That is reflected in the driver-side LSD axle’s design (the passenger side axle is the same regardless of LSD). For this reason, LSD axles cannot be used in a non-LSD transmission and vice versa. They are quite similar but also very dissimilar.
The hub ends match exactly:
On the non-LSD axle, the middle parts are similar but longer:
The “business endpoints” are located here. I’m not sure if all OEM axles were labeled in this fashion, but the LSD is labeled “J G while the non-LSD is designated “J L. Despite both axles having the same overall length, the LSD axle has substantially longer splines:
If you’re still having difficulties understanding how everything fits together, the following illustration will help:

Has the Honda Civic LSD?
A limited-slip differential with a helical design is powered by a six-speed manual transmission that is designed for sports (LSD). When coming out of a turn, the Civic Si accelerates forcefully and with assurance thanks to the LSD since both wheels can distribute torque to the road more evenly than they could with a traditional open-type differential.
The benefits of a limited slip differential
Although no differential is flawless, limited slip differentials do provide a number of advantages over a typical open differential.
When one tire loses traction, limited slip differentials adjust, giving you more control even on slick or bumpy roads.
A limited slip differential makes use of engine power more effectively to boost a car’s power and speed, resulting in a smoother and more pleasurable ride.
Even on common roads, LSD units can aid in maintaining near-perfect traction to provide a safer and more comfortable ride.
By keeping one wheel from spinning unnecessarily, limited slip differentials can help to reduce tire wear and tear. Axle shafts follow the same rules. A longer lifespan is the result of shifting torque because it results in reduced pressure.
A limited slip differential delivers significantly more traction and grip than a typical open differential system, even while driving over dust, sand, and rocks.
What distinguishes an open differential from a restricted slip differential?
The differential is a concept that dates back to ancient China, but modern advancements in technology and design have altered how we utilize them in cars. It might be challenging to distinguish between differentials because there are so many different sorts. In this comparison of open and restricted slip differentials, it’s critical to take a closer look at two common configurations.
Our guide will examine each one’s advantages and describe how it functions. To give you a complete view of your possibilities, we’ll also describe a couple more systems you might not be familiar with. Let’s quickly review your query first.
The function under slipping conditions distinguishes an open-slip differential from a limited-slip differential. The limited-slip differential delivers power to the wheel with the most traction, whereas the open differential sends it to the wheel with the least resistance.
There is much more to it than just this rapid response, though. Here is everything you need to know about how these two differ from one another.
How can a limited slip differential malfunction?
Your wheels’ differentials may experience apparent indicators of wear or malfunction. Tyre damage, vibrations, trouble controlling, and grinding gears are the top 5 signs of faulty front and rear differentials. As soon as you notice these symptoms, you may take action and bring your car to a differential-specialist mechanic to have the issue evaluated and fixed before further harm to your vehicle is done.
Damage to Tyres
To minimize unequal wear and tear, your car’s tyres must rotate at various speeds when rounding a corner. Your tires will wear unevenly and have worn, flat tread if your differentials aren’t working properly. Before your tyres deteriorate and you have to replace them as well, having your LSDs examined early will save you money.
Whining Sounds and Vibrations
There are several ways that poor LSDs can result in this. First, the universal joints in your diff may fail, resulting in drive shaft vibrations and a whining sound. Second, you may experience severe vibrations due to a fluid leak in your differentials. They will start to malfunction very soon if that is the case.
Control
Since the purpose of LSDs is to improve vehicle control, if you feel like you’re losing some control of your car while driving, there’s a significant probability that something may be wrong with them. Time to have it looked at.
Grinding Gears
You will feel and possibly hear a perceptible grinding of the gears, especially during change, when your differentials malfunction or become faulty. You will hear a whining sound and a low humming sound that intensifies over time.
Which is preferable, a locking differential or limited slip?
The best traction available for your car is provided by limited slip differentials. Even while locking differentials may provide you with good traction, limited slip differentials will provide you with higher traction.
To begin with, they will make it simpler to turn on slick, rainy roads. Consider installing limited slip differentials in your car if you live in a region where it rains and snows frequently.
The treads on your tires will also continue to be in good shape as you frequently accelerate. The limited slip differentials will also be completely silent. In contrast, locking differential car tires quickly develop worn tread.
Naturally, limited slip differentials don’t lock all of the wheels on an axle at once. Additionally, it has been discovered that some restricted slip differential variants are physically weaker.
As a result, you’ll probably need to replace them more quickly than you would with locking differentials. Some limited slip differentials may pull from one side to the next if you have a front axle application.
With a limited slide diff, is it possible to drift?
First and foremost, I want to stress that there is no right or incorrect decision—differential preference depends entirely on the driver! For those of us who work with Nissan 240SXs, open differentials, or “difs, are the norm. However, occasionally, and especially with the S14, you will discover some viscous Limited Slip Differentials (VLSDs), which place you in a whole different situation.
Why? Because welded differentials or 2-way aftermarket differentials in the dry offer better performance and predictability than VLSDs, which will work well for drifting in the wet.
For you “hardcore drifters,” it’s important to keep in mind that safety is also a key consideration. If you’ve ever had to drive home in the rain after street drifting and you’re running on cords, having a locked differential keeps your rear end under control rather than causing the differential toss around while deciding which wheel to transfer power from a VLSD.
The similar problem exists for other RWD applications as well, including Miatas, RX-7s, and BMWs. You’re going to want something predictable and able to withstand the thrashing of extreme sideways driving when it comes to drifting.
We therefore have two options: 2-way or welded. Some may now inquire, “Hey, what about 1.5-way? I’ll respond to it. The 1.5-way is mainly designed for the road course racer who wants to exit that turn as quickly as possible and has to be able to accelerate and decelerate without suffering significant traction loss. Is that clear?
Is there a limited-slip differential on the Honda Civic?
A more thrilling sensation is provided by performance driving thanks to the limited-slip differential.
The Aspect:
The limited-slip differential, which is typically only present on high-powered vehicles, reduces front-wheel slippage, enhances steering accuracy, and enables the driver to accelerate out of a corner more quickly.
- This limited-slip device gives the driver better steering control and a quicker steering reaction when accelerating and turning. It also helps reduce front-wheel slippage.
- The Civic Si comes standard with a limited-slip differential, but its rivals often only offer it as an option, if at all.
Is there a limited-slip differential on the 2007 Honda Civic Si?
It’s no secret that we at GRM have long been admirers of the Civic Si, and over the years, we’ve even had a number of them as project cars. We were therefore rather eager to get inside the most recent model, the 2007 Honda Civic Si sedan.
Honda offers the Si in coupe and sedan body styles, both of which feature the same 2.0-liter, 197-horsepower engine, limited slip differential, and six-speed manual transmission.
The most recent Si has a huge list of features, including an inbuilt navigation system with a big screen that pulls out for access to the CD drive and a 350-watt sound system with seven speakers and a subwoofer. Of course, the extra doors make it simpler to get into the back seats, but they also add 60 pounds.
The most secure Civics ever are the most recent models. In government crash tests, they scored four stars for rollover crashes and front seat side impacts in addition to five stars for front impact and rear seat side impacts.
Other staff views
I had forgotten how much I adore this vehicle. I am aware that some of you claim that the fact that I have had multiple Civic Sis taints my opinions, but I truly, really like this car, especially in sedan form. The K-series engine, limited-slip diff, crisp shifter feel, and seats are all things I adore. I understand that not everyone will like the dashboard, but I could get used to it. In all honesty, I’d choose the sedan over the coupe for a daily driver because I don’t think the extra weight will make much of a difference in town.
What is the lifespan of limited slip differentials?
As it refers to standard work vehicles rather than the countless articles I discovered that are written for performance-oriented dirt track racers, drag racers, drifters, and off-road aficionados, this information seems fairly useful.
Does anyone know what model, OEM brand, or component package the 2017 Transit Wagon axle belongs to? Any specifics on the LSD components, please? I suppose I should at the very least make an effort to learn more about the systems that our Transit is powered by so that we can take excellent care of it.
