Talk about a long weekend but well worth it!👏🏼

Customer called last Friday saying he was doing his weekly/biweekly check of everything on his truck as he does before getting out on the road and found metal in the rear ends. He brought us the truck that morning and wanted us to replace them but need to leave out on Sunday. By Friday evening we had 2 new rear ends in our parking lot getting unloaded thanks to our amazing parts guys up at World wide of Crossville and new hub assemblys on Saturday thanks to our awesome sales man at Peterbuilt that went well out of his way to make sure we were taken care of. 🙌🏻

We spent 16/17 hours Saturday into Sunday morning making sure this truck was ready to go Sunday by lunch for our customer.

We are here for you!

Why is it crucial to change your cabin air filter?🤔

Cabin air filters (very often over looked) in semi-trucks are needed for both the drivers health and the trucks hvac system, often trapping 90-99% of contaminants like dust, pollen🦠, and soot before they enter the cab. These heavy-duty filters, often located behind the glovebox or in the HVAC system, and are typically changed every 12,000 to 20,000 miles (or more often in dusty conditions), they enhance HVAC efficiency, keep your drivers breathing in fresh air and can even feature activated carbon to neutralize odors.

New and old cabin air filter that has never been changed by a previous shop! Just because it may sometimes be a pain to access it still needs to be changed! 🛠️⚙️

You know it took a lot of effort to get the tires to seat when it takes a whole bucket of tire soap for two tires. 😮‍💨

Remember if you buy tires to keep on hand always store them standing up! If you lay them down and stack them to store till use you will likely run into this issue when trying to mount them. 🛞

Sometimes I’m lucky enough to get to walk into the shop and see what he’s got tore apart. Usually I’m out getting parts or in the office. 👩🏼‍💻

This mulching head had all the bolts stripped out of the seal housing. Got it all tore down, repaired and ready to go. ✅
