No, this truck doesn’t have any rot. It is what we would consider “rust free” up here.

I wouldn't know. I just saw you were in Wisconsin which, to me, meant snow and ice which means salted roads. In my mind, anything north of Tennessee is a rusty hell.



Anyway, have you tracked it down to a panel flexing or is it still possibly something loose and moving, bumping a panel?

is that what is wrong with your existing mirror? if so I just bought the china plastic gear off of ebay put it in and good to go, you just need a vice to do the spring part, I didn't even have to take the mirror off the truck, just took it apart, put the gear in and put it back together, it did take me 2 tries the first time it wasn't lined up right inside. in the video I watched the guy did some grinding and etc which does not need to be done at all

Y’all need to just let me be lazy. Yes I believe the gear issue is the only problem. The power fold went out on the passenger side which really didn’t bother me but now I’ve noticed that the whole mirror assembly is flopping around in the wind. I was thinking that it would be worth a new mirror if I could get some with puddle lamps as well (have every other option).

I finally got this done. My dumbass welded it on the wrong side of the muffler, should have been on driveshaft side. Ended up needing a decent "clearance" dent to fit. Haven't hit the highway yet, just a quick trip around the block, it has definitely changed the tone as far as i can tell at idle. Can still hear under acceleration, my intake drones under mild load also [emoji2373].

Picking her up from a4 wheel alignment today. My Yukes finally in good enough shape to pass an insurance inspection

Over a few weeks I did: uppercontrol arms, lower ball joints, inner outer ties rods. front wheel bearings.
e brake pads and cable. interior head light switch. high/low beams wired backward. front main seal, oil cooler block off plate. repaired the wiring harness for the throttle, plus replaced foot pedal. re wired the park sensors, replaced one park sensor. replaced rear u joint. replaced squeaky accesery belt pullies. ac belt tensioner. front differential output seals and bearings.
also replaced the fresh air/recirc vent motor.

picked up the yukon denali for $6k, ive put about $1300 in parts into it. figure im well ahead of the game, would of cost the old owner a mint to get everything repaired at a shop.

next best one i saw for sale the guy wanted $12k for it. it was an 08 with 270000km. one i bough is an 07 with 185000km. (or about 110 000 mile)

Nice! I’m interested to see / hear the difference! What RPM was your worst drone?

I'm 6 speed and was 1500-2500 range. Around town i drive in M5, afm activates in 6th under light load. Kinda interested to see what that does at highway speeds. Also interested to see what changes with long tubes and ory that will be coming in the future.

Keep us updated. And yes I definitely expect it to change after installing longtubes.

It's the family road trip vehicle, but also my dd. Looking at doing an L96 with btr stage 2 v2 truck cam, and an LSA top end setup. I may put cats in the long tube's if needed just to tame if i have to. Otherwise ill be looking at finding a stock 6.2 catback and start over. I like to tinker and this gave me something to do.
