What Our Customers Are Saying

These guys are awesome, they service our fleet of trucks and always provide excellent service and timely updates plus do the job right the first time.

Great place to get work on oversized vehicles like RV’s and trucks.

Always professional and never disappointed, love TLC

These guys were great. I reached out to them on a Friday and the fit me into the schedule on Monday morning. Everything went fine and I was out the door quickly.

I recently purchased a car and took it to TLC for its first service! I was working with service Advisor, Brian and him and his crew took amazing care of my car for me! I have always gone to dealerships for my service and always felt taken advantage of. This was NOT the case here! They’ve got my business for life!

Brought my suv in for an ac issue. Pete and the guys were excellent in communicating what my truck needed and when it would be complete. Got my truck back and ac felt just like it did when it was new. Will be highly recommending them to friends and family.

Keep Your Peterbilt Kingpin Working Longer

Peterbilt Kingpin Replacement

If your Peterbilt is wandering, pulling, or chewing through steer tires, worn kingpins may be the cause. Our team inspects play with dial indicators, evaluates bushings and bearings, and checks tie‑rod ends and drag links before recommending repair. We press out old pins, install quality replacements, ream/fit bushings to spec, and advise on alignment for a precise, long‑lasting result.

Turnaround & Cost Transparency: Kingpin replacement time varies by axle type, corrosion, and parts availability. Pricing depends on OEM vs. premium aftermarket kits and any related steering/suspension components discovered during inspection. Call for a detailed estimate – share your VIN and symptoms for the most accurate quote.

Frequently Asked Questions

What Peterbilt models do you service?

We service popular models like 579, 389, 567, 365, and 520, along with many others. Vocational configurations (dump, mixer, refuse, day cab) are fully supported. If your model isn’t listed, contact us and we’ll confirm.

Can you diagnose PACCAR MX and Cummins engine issues?

Yes - our OEM‑level diagnostics cover PACCAR MX‑11/MX‑13 and Cummins engines. We test fuel delivery, turbo/boost, EGR, and cooling systems to locate root cause. You’ll get a clear plan before any repairs are made.

Do you perform NYS and DOT inspections for Peterbilt trucks?

Yes. We are an Official NYS Inspection Station and we perform DOT inspections. If your truck needs work to pass, we can complete the repairs and retest. You leave with documents ready for compliance.

How do you handle Peterbilt kingpin replacement and alignment?

We measure steering play, inspect bushings and bearings, and replace kingpins with quality kits. Bushings are reamed/fit to spec and components are torqued properly. We coordinate/advise on alignment to protect new components and tires.

How often should I service my Peterbilt truck?

Intervals depend on duty cycle, hours, idle time, and environment. Many fleets begin with 15,000–25,000‑mile oil intervals and adjust based on oil analysis. We’ll build and track a PM plan that fits your routes.

Do you work with fleets and provide maintenance records?

Yes, we maintain detailed histories for every unit. You’ll receive inspection checklists, photos, and recommendations after each visit. This documentation streamlines compliance, budgeting, and resale.

Can you perform DOT inspections?

We handle DOT annual and periodic inspections for Peterbilt trucks and trailers. You’ll receive a clear report, repair recommendations, and timelines. We can complete fixes on the spot to reduce downtime.

What should I do if a warning light or fault code appears?

Don’t ignore it - continued driving can trigger derates or damage. Safely park, note the message/code and symptoms, and contact us. We’ll retrieve data, test affected systems, and recommend the right fix.
