If you have two of the same kind of vehicles side by side and they both have the same issue, that ain’t a coincidence, baby…

And it happened here!

A mechanic in Texas posted a video on TikTok and showed viewers a problem he found with two GMC Denalis.

The video showed two GMC Denalis on lifts in an auto shop.

The mechanic said,  “Can y’all guess what’s wrong with both these GMs?”

He continued, “On today’s episode of ****** up Fridays…”

The man showed viewers the undercarriage of one of the vehicles and said, “Spun bearing.”

He walked to the other Denali and said the same thing.

Uh oh…

It doesn’t look like this problem was a coincidence!
