Another fun one in the books!

Is the catalytic converter in your vehicle keeping you down?

* Tip Of The Day *

More Than Just Starting: Powering Modern Vehicle Electronics

Years ago, a car battery's only major job was cranking the engine. Once the vehicle was running, the alternator took over. Today, passenger vehicles are packed with advanced electronics that pull massive amounts of power.

A premium battery acts as a crucial voltage stabilizer for sensitive onboard systems, including:

Advanced Driver Assistance Systems (ADAS) like lane assist and automatic braking.

Infotainment systems, GPS, and Bluetooth connectivity.

Complex Engine Control Modules (ECMs) and body control computers.

If a battery's voltage drops even slightly below optimal levels, it can trigger ghost diagnostic trouble codes (DTCs), cause intermittent electrical glitches, or place unnecessary stress on the vehicle's alternator, leading to premature alternator failure.

If you are having issues with your charging system in your vehicle give us a call today to schedule an appointment to have it tested!

Did you know we install vehicle accessories as well as repairs?

This 09 Dodge Ram 2500 6.7L came in with an issue with their old worn out aftermarket rear airbags where they would slowly seep out air over time. Found the bags to be badly weathered and leaking air slowly out the seems. We provided and installed a new Air Lift Kit to correct this issue. Results turned out nice and bags now hold proper desired pressure without leaking.

If your truck is sagging in the rear due to heavy loads, then this is a nice viable option to keep your bumper off the ground and to keep your rear suspension from being bottomed out.

If your vehicle(s) needs any accessories or repairs remember to give us a call, as we can get you handled in a timely fashion!

πŸš—πŸ’¨ Ever wonder what’s keeping the air inside your vehicle clean?

Meet your Cabin Air Filter. It’s your vehicle’s unsung hero, acting as the ultimate gatekeeper between the outside air and the air you breathe while driving.

Over time, this filter clogs up with dust, pollen, road debris, and allergens. Here is why keeping it fresh matters:

Breathe Cleaner Air: A fresh filter traps up to 99% of airborne particles, keeping dust, mold spores, and seasonal pollen out of your lungs and off your dashboard.

Boost Your AC & Heating: When a filter is clogged, your HVAC system has to work twice as hard to push air through. Replacing a dirty filter instantly improves airflow and helps your AC blow ice-cold.

Eliminate Musty Odors: If you notice a stale, dirty-sock smell when you turn on your vents, a contaminated cabin filter is almost always the culprit.

Defrost Faster: Restricted airflow makes it much harder for your defroster to clear moisture off your windshield on rainy or humid days.

How often should you swap it?
Generally every 15,000 to 30,000 miles, or at least once a yearβ€”especially after heavy allergy seasons or driving on dusty roads.

πŸ“… Dropping your vehicle off for service soon? Ask us to check your cabin air filter while it's here to ensure you're breathing easy all summer long!

Another day, another Differential Bearing Rebuild.

This 12 Ford F-150 came in for a growling/howling from the drivetrain area around 50ish MPH. Drove vehicle on the lift and found noise to be coming from the rear differential. Removed rear carrier and found bearings to have failed due to bad fluid & rust. Cleaned axle housing assembly of rust/debris and installed new bearings to correct this issue.

Simple services on differentials can prevent this failure. Remember to have your drivetrain fluids inspected/serviced every so often. Not just your engine oil.

Out with the old and IN with the NEW on this 12 Cummins!

Customer had an internal failure within the stock turbocharger assembly. Upgraded customer to a 13-18 style turbocharger with a jumper harness to make it plug and play!

This BD Turbo is a good stock replacement assembly for those looking for a replacement turbocharger on their Cummins without breaking the bank!

Another day, another vehicle repaired and back on the road!
