So I wanted to share this pic (and hopefully confirm) that the AT4 has a different UCA than the Denali/SLT/SLE.

Everything I read online just said the strut assembly is longer but I haven't seen anything on the control arms.

Does anyone have a pic of a non-AT4 UCA?

Here's the pic of the AT4 UCA.

  That's always been the rule with prices at the pump. Rockets and feathers. This week's/last week's spike, well.. the doctor said if your excursion lasts longer than 4 months, it's just a war. There's active conflict in the Strait again.

  yes....if they are reacting to something. Could be a little mud/snow build-up..(triggers mine at slow speeds) but often I'll just get a front sensor blocked message. Maybe a park sensor starting to flake out?
