Vive la Differential at KPS Princeton Garage in Princeton

Posted July 26, 2026 1:28 PM

There are a lot of drivers in Princeton who are due for a differential service, but had never heard of a differential before. With front-wheel drive being so common in NJ these days, the differential is just taken care of during a transmission service, so most Princeton folks don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of your mind. It's not uncommon for people in Princeton to not know they have a differential, let alone know that it needs service.

To better understand what a differential does, think about a track at any NJ high school. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That's to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner has the same distance to run.

The differential compensates for the difference in speeds between the inside vehicle wheel and the outside wheel in a turn, because they have to travel together through slightly different distances.

It's a very important function. When you think of it, all the power to get a vehicle moving goes through the differential. Most cars weigh between 3,000 and 6,000 pounds (1,400 and 2,800 kg) – trucks even more. The power from the engine goes through the transmission and then through the differential to the drive wheels.

That's a lot of work and requires very heavy duty parts. And those parts need protection. The differential fluid lubricates the gears in the differential and keeps them cool. The fluid eventually gets dirty and worn down. Some kinds of differentials require special additives that break down over time. So manufacturers recommend intervals for when to replace your differential fluid.

Your knowledgeable KPS Princeton Garage service technician will drain the used fluid and check it out for metal bits, which could be a sign of excessive wear on the gears. He'll then replace the fluid and install the additives if necessary.

Your KPS Princeton Garage service advisor can look up the vehicle manufacturer's recommended service interval or you can check your owner's manual.

At KPS Princeton Garage, we've been providing quality automotive service for our valued Princeton customers since . If you need to schedule differential maintenance, or any other automotive service, give us a call at 732-297-9515.

Air Conditioning Maintenance at KPS Princeton Garage in Princeton

Posted July 19, 2026 12:37 PM


Warm weather or cold, Princeton drivers still need to think about their vehicle's air conditioning. Most Princeton people don't service their air conditioning until after it fails. At KPS Princeton Garage, we can advise you on your vehicle manufacturers preventive maintenance schedules for air conditioning service, just as we do for transmission service, oil changes and so on.

Maintaining your air conditioning system means that you always have enough refrigerant to properly do the job. Small leaks in the vehicle's air conditioning system allow the refrigerant to escape and the system can't cool the air as well. We see that a lot at KPS Princeton Garage in Princeton.

The refrigerant also contains oil that lubricates air conditioning components and keeps the seals resilient. Low refrigerant and lubricating oil means that the air conditioning parts will wear out prematurely, and all Princeton vehicle owners know that air conditioning repairs can be costly. At KPS Princeton Garage, we recommended that the air conditioner be run regularly, even during winter months, to keep the parts and seals lubricated.

Princeton drivers need to be aware that there's one more thing that isn't directly related to air conditioning service but does impact the quality of the air in your vehicle. And that's your cabin air filter. This filter cleans dust, pollen, pollution and other impurities in the air that come from the heater and air conditioner. The cabin air filter needs to be replaced when it's dirty. If you don't, it'll start to smell. Not all vehicles have one, so ask your KPS Princeton Garage service advisor to check your cabin air filter at the same time they're doing your air conditioning service.

The Fallacy of Cheap Tires

Posted July 12, 2026 1:19 PM

 

Do you ever shop for shoes in one of our Princeton area shoe stores?
When buying a running shoe, is quality important?
Does durability matter as long as the shoes look fabulous?
Would you rather have one pair of long lasting shoes or two pair of lower quality shoes at the same price?

Is the warranty important when buying tires?
When you choose new tires in Princeton, what's the most important factor for you?

Give us a call at KPS Princeton Garage at 732-297-9515 for tire recommendations.

You know, buying tires in Princeton is a big deal. It's a big ticket item so you know you'll be spending a lot. You're not only concerned about the price, but you want to know that it'll be a long time before you need to buy new tires again.

And of course there's the safety aspect as well. The tires do a lot of work – they carry the weight of the vehicle and you and your passengers. They need to be up to the task. You want to be sure they hold the road and provide good traction. If you carry heavy loads or tow a trailer, the tires need a high load rating to be up for the job.

As a tire professional, I think it's important that people understand the effect of price on a tire's performance and durability. When I was a kid, my dad had a saying, "Pay twice as much and buy half as many."

Dad applied that to a lot of things. He thought that one high quality suit would last longer and look better than two cheap suits. The saying really seems to hold true when it comes to shoes and boots, too.

I buy high-quality work shoes because I spend a lot of time on my feet. They're more comfortable, have important safety features like steel toes and non-slip soles and they last at least twice as long as cheap shoes. I feel I get very good value for my money.

I apply the same thinking to tires. The major tire brands that you're familiar with are known as Tier 1 tires. These tires are well-engineered and very high quality. Comparable tires are usually in the same price range from brand to brand.

Stepping down in price you come to private label tires. Some large tire store chains carry tires with the chain's own brand. It's important to know that most private label tires are built by the same Tier 1 brands that you are familiar with, so they are a quality product. You can ask your tire professional who makes their private brand.

The lowest priced tires on the market are Tier 3 tires. These tend to be imported from China or South America. Since you get what you pay for, you can't expect a Tier 3 tire to deliver the same performance and durability as the others.

So let's say you need new tires. You've determined the features you need. So you have several options, including price options. Now, you've probably heard the term 'it's a 40,000 mile/64,000 km tire' or 'it's a 60,000 mile/97,000 km tire'. Simply put, the manufacturer warrantees the tire for 'X' number of miles/kilometers. If that's important to you, look for the warranty.

What's the difference in the tires with higher mileage warranties? It's the rubber compounds and the amount of tread material. As you might expect, you'll pay more for the longer-lasting tire.

Now the cheapest tires you can find won't have a manufacturer's mileage warranty, or if it does, it'll be relatively low. That brings us back to dad's saying; if you buy the cheapest Tier 3 tire you can, you will likely go through two sets in the time it would take to wear out one set of good quality tires. And the good tires won't cost twice as much, so you'll end up paying more per mile/km driven with the cheap tires.

Hey, I realize that sometimes the budget will only allow for a Tier 3 tire. I make them available for my customers who need them because I would rather see them driving with safe, new tires than pushing their old tires beyond their safety limits. But at KPS Princeton Garage, we always counsel our customers to buy as much tire as they can afford, because it will be much less expensive in the long run.

Your tires are the only parts of your vehicle that touch the road. You're only as safe as your tires are well built.

Buy value – not price.

Hey Princeton Drivers; What Is the Most Distracting Food?

Posted July 5, 2026 1:36 PM



So what is the most distracting food to have in the car while driving around Princeton?

Is it:

  1. A Hamburger;
  2. Coffee;
  3. A Soft Drink, or
  4. Gummy Bears?

Well, you may be surprised to learn that all but the gummy bears are in the top ten most distracting foods when you are driving. But if you chose 'coffee,' then give yourself an extra two points.  Coffee is the number one food distraction for drivers in Princeton and around the country.

Food distractions cause 25 percent of all car accidents; over a million and a half each year!

You'll notice that all of the top ten distracting food items are messy. Messy foods are the types of food you might spill (very distracting!), then try to clean up (a safe-driving impossibility!). If you gotta eat on the run, take five-then drive. You'll thank yourself later for two reasons: one, that you can actually relax for just a moment in our fast-paced world, and two, you won't have to worry about getting that cinnamon roll frosting out of your dashboard after that near miss.

Keep drinks in spill-proof containers, too, so you can keep your eyes on the Princeton road without worrying about where that spill is headed.

So, taking a food break… or filling out accident reports. We don't have to ask you which you prefer; it's a no brainer.
