    What should the Rear Sway Bar height be set at?

    That is interesting. The rear of my 2011 Yukon Denali XL 6.2 with the towing package had no rear sway bar from the factory. I purchased it new. I bought a Helwig for the rear when I upgraded the stock front sway to Helwig. Made a noticeable difference in handling.

    PPV brake lights inop

    How about wire harness connections. Those plugs may be different with a police package. It would be good to look at the wiring diagram for both to see if the inputs are the same. I bet that is your problem.

    Need opinion — upcoming road trip

    I would have done the same thing as you did given the situation. However, I continued thinking through this by adding some other variables that changed my mind. Here's why. I was looking at the same questions with The Queen's 200,000 mile 2011 Yukon Denali XL 6.2 I bought new. Always...

    High mileage 6.2

    Just sold my 2011 6.2 Yukon Denali. 208,000 miles. Never the first bit of trouble, but had I kept it I would have done the lifters (never a problem, but borrowed time), water pump, fuel pump, belts, hoses, plugs and wires, fluids (transmission and all wheel drive items), hard check of front...

    Yukon XL rear shock

    I had a 2011 Yukon Denali with factory adjustable shocks driven by an air compressor. They leveled out quickly after loading them. Never had to replace the shocks, but the compressor ran out of breath at about 150,000 miles. My 48 years of experience tells me that if you begin experimenting...

    How to easily change spark plug for cylinder #8 in 10 minutes, no hassle!

    Techron is the best stuff. There are plenty of YouTubes out there on those products. i have direct experience with leaky injectors on my 6.2 CTS V at 45,000 miles. On occasion I would start it up and blue smoke literally enveloped it. It was embarrassing. My mechanic gave me an article in a...

    Hello From California

    I like your choices for driving. Newer trucks are too complicated.

    GM must be doing well

    For what it is worth, I miss my 2011 Yukon Denali XL. It had 208,000 miles but was still in great condition. A rock chip here and there, but that was it. I still hated those 2011 headlights though. I had to keep checking to see if they were turned on or not. My 2023 was just too dam...

    Fuel Injection Cleaning Kit?

    Lake Speed is correct. Techron is the only gas additive that works. In your case you might try a can a tank for about 5 tanks of premium. Solved my injector problems on my 2010 CTS V. All of a sudden it looked like a fog truck on occasion at 40,000 miles when I would start it. Sold it at...

    Transmission or slip yoke?

    That description is classic of a slip yoke needing lubricating. The giveaway was "If I accelerate lightly from a stop or I ease the brakes to a complete stop, I don't have the issue. It's only when I'm a bit more aggressive with either that I get the symptom." Lubricate the slip yokes. If...
