Hummer suddenly slowed down
 

Hello all, long time owner of my 2005 Hummer H2 and it’s been a fantastic vehicle. However I was going down the interstate cruising at 80 and suddenly it jerked forward and slowed down to 60. So I hit the brakes and got off the interstate ASAP and noticed my right front wheel bearings went out and locked up. Got the bearings replaced but the Hummer still is suddenly stopping. Any ideas what this could be?

It is performance anxiety, LOL!

You will have to provide more details, and what you already checked. It is likely unrelated to wheel bearings, and that was just a fluke.

Bearings do not normally seize and "lock up". They normally sequel and vibrate first, unless you have catastrophic failure which then usually eats your spindle also.
Dude, your Hummer has demons.
