GeorgeB’s 2013 Suburban LTZ “Fin”

[George B]

I just did mine in October at 138k. I had bad upper/lower ball joints and a bad inner tie rod. I replaced entire control arms both upper and lower and inner/outer tie rods on both sides. The wheel bearings are still good, so didn't mess with them, but the front brake pads were toast so replaced the pads and rotors a couple weeks later.

You use Moog or ACDelco?

Moog, from RockAuto

On my third tank of non-ethanol 91 and fuel composition was reading 4%. Reset it with mu Tech2 and it only changed down to 3%. Not sure if that is correct or not. I went from 70% on E85 down to the 4% in just two tanks full.

Going back to the 88 oct E-15% or E85. this stuff is too expensive to run consistently!

The Tech 2 always resets it to 3%. That is normal.

Noticed an odd behavior.
1/4 tank of fuel
Coasting down from 50mph into a right turn with a yield. When I get back on the the throttle I experience a hesitation to accelerate. Once the trans figures out it need to downshift the truck goes as it should.

Seems to only happen at or below 1/4 tank.

I am going to try to record a snapshot of the fuel data tomorrow before I fill up. Not sure if I can record the trans data at the same time or not.

Runs fine with the scan tool hooked up.

Just ordered a warranty replacement set of rotors for the rear from RockAuto. I have 40k on them and they are warped pretty bad. Going with the same Raybestos coated ones. Hope these are better.
