🚐💪 Rare 7.3L 4x4 Work Van Sighting! 💪🚐

Wasn’t planning to film today, but when this beast rolled in, I had to share it with you guys. What looks like your typical beat-up work van turns out to be anything but…

🔥 Under the hood: the legendary 7.3L Powerstroke
🛠️ Possibly needs injector cups – we’ll see…
🚙 But here’s the kicker – it’s been converted to 4x4, with what looks like an '08+ Super Duty front axle, manual transfer case, and front drive shaft in place. Yup, it actually works!

These vans were never 4WD from the factory. There was one company called Quigley that did conversions, but this one? A super clean, hand-built setup with locking hubs and off-road upgrades.

I geek out over stuff like this – hope you do too!
👉 Drop a comment if you want to see us do the injector cup job on this rig.

!!!BUYERS BEWARE!!!

Customer purchased this beauty less than a month ago. (first pic)

He noticed a small amount of coolant leaking so brought the truck in for a diagnoses from our resident Powerstroke Guru, Quinton.

A quick combustion leak test determined blown head gaskets. You can see exhaust bubling up. (second vid)

We showed the customer the difference in fluid colors. (third pic) The light green on the right indicates exhuast present in coolant, NOT GOOD! The fluid on the left is the original color of the testing fluid.

If you’re planning on purchasing a used vehicle we can help you buy with confidence. Our Pre-purchase Inspection Service could save you thousands!

A customer brought in their RAM 3500 HD. Truck quit moving while making a turn. Another shop quoted him FIFTEEN THOUSAND DOLLARS!!! for a new motor. 🤡 🙃

He called us for a second opinion. Quinton, our master mechanic, told him it sounded like a flex plate, and we could take a look ASAP. 🔍

BAM! 🕵️ Cracked flex plate found and replaced (first pic), also swapped the started new starter due to damage (second pic).

We SAVED the customer OVER $13,500!!! 🤯 💸
