It's been cold in Denver, but the temps have been getting up to a high of about 50 for the last three of four days.

This morning (hovering in the upper teens and low twenties), I backed out of my garage and there was a vibration...more like a quick pulsation. It kept a steady "beat"...didn't matter if I slowed or sped up.

I didn't feel it after putting the truck in drive and going on my way.

When i got to work (3 miles streets, 10 miles highway at the 65 limit), I put the truck in reverse and nothing unusual.

I've never experienced this before and hope it's a temperature related issue (even though this didn't happen last year).

Because of a recently very pricey EPB repair, I don't engage it unless absolutely necessary.

Anyone have this?

 

Possibly the abs or traction control?
