    front end binding in AWD

    Replacing the transfer case fluid may reduce it, but this is pretty normal for a 2001

    08 tahoe ltz cyl shutdown

    Normal operation for a 07-14 model. The newer 15+ engines hold V4 mode longer. You will be hard pressed to keep it in V4 on a flat at more than about 60 mph, probably only downhill at 70.

    Help me troubleshoot a vibration

    I would not put antiseize on the spline, it will get into the transfer case oil. the spline should be lubricated by the t-case fluid. If fluid is aged it may cause a stop clunk, but should not cause a vibration. II was pretty sure you had a u-joint or other driveshaft issue at your first post.

    Friday was a sad day RIP Avalanche

    When towing you want about 10-15% of the total trailer weight on the hitch. Too little weight on the hitch, or front of the trailer promotes sway. Also the faster you go, the more prone to sway. I used to have a sailboat that required I put the anchors, sails, and all gear at the front of the...

    Outside Tire Wear & Alignment Good

    No! If not tire pressure then alignment, or maybe making an unusual number of full lock turns.

    Air filter oiled vs dry

    The oiled K&N pass a lot more air when very clean. Airflow drops dramatically as it gets dirty. Almost nobody needs more air than the stock filter. The stock filter passes more air for a longer time. for 99.9% of the people out there, the stock filter is your best bet. If you decide to go with...

    5.3 Overhaul

    Agree with iamdub, go with the high volume pump. The engine probably is a bit worn, but pumping a higher volume of oil should bring the pressure up. I do not believe there is a screen under the sender on a non-AFM engine

    Transmission or ECM?

    I agree that withall the seemingly unrelated codes a bad ecm is a possiblity. All you can do is to check the grounds and wiring for codes that set, and if no fault is found, try an ECM.

    What gasoline brand and what octane do you guys use?

    Top tier fuels (www.toptiergas.com) have higher detergent levels and will keep injectors and valves cleaner than most other brands.

    People with kids help

    II heard about this some years ago. It is by design. If I remember correctly, t has to do with the width required for a child seat and there is not adequate width to legally have 3 across. I do not have any information on why the driver side was the one eliminated.

    Is it worth buying a GM TECH 2 scanner?

    For about $170, you can get an Autel scanner that will read and clear codes and read data in almost all modules. It does not have 2 way communication though, it will not command changes in the vehicle. I am pretty happy with it. Autel MD802 Maxidiag Elite 4 System Diagnostic Tool Engine ABS...

    Towing mileage

    I have to agree with rjackson, it sounds normal to me. I struggle to get 10 mpg on flat roads with the cruise at 61 mph.

    Started cleaning sludged engine

    When you get this running, keep a close eye on your coolant. A lot of the time when you have heavy sludge it s because coolant s getting into the oil.

    New Hoe Owner. First debacle

    Dirty MAF might set a different code, might set fuel trim codes. I would try cleaning it, and making darn sure there are no air leaks between the MAF and the thrttle body, and check the PCV pipes fr leaks If it holds 50-55 psi fuel pressure while driving, including WOT acceleration, I would say...

    Popping noise coming from front end?

    The leveling kit could definitely be the source of your noise, I have seen it before.

    Cold air intake? Yea or nay?

    Yes, pan has to come off.

    What kinda fuel y'all run?

    E85 has high octane just because alcohol is by nature high octane, but there is less energy per gallon so fuel mileage drops by about half. It is also prone to water contamination because it absorbs water, with gasoline the water tends to separate. but clean E85 will indeed give you high octane...

    Chevy Dealership for scheduled maintenance...on modified Tahoe?

    Removing the tune when you take it to the dealer is a waste of time. If you ever have an engine or driveline failure that you try to get warranty on, GM will review the programming history and detect that the cal has been installed and removed multiple times. you cannot hide it. At that point...

    2017 Denali fluttering when accelerating. VIDEO

    I believe you are hearing characteristic noise that comes in with V4 engine operation. The valve in the exhaust is intended to minimize it. I don't believe there is anything that will eliminate it in the long term. I have seen several exhaust systems replaced for this but the noise comes back.

    This will kill your battery!

    It looks like you have a glitch in the body control module (BCM) or in it's programming. If you are still under warranty I would have the dealership address it.

    What is this plate on my oil pan???

    It is a sound damper, to dampen oil pump noise.

    2008 5.3 engine replacement

    If you now live, or ever live in an area where emissions are tested, you need the same type engine that came in the truck, with functioning AFM. Many mechanics will not do an AFM (DOD is the same thing) delete because t is tampering with the emissions, and subject to a large fine.

    Service airbag light came on?

    There are a ton of possible causes. You need to get a scanner on there to see what component is setting the code to have any reasonable chance of fixing it.

    Buying a travel trailer, what's my safe towing capacity?

    I would also get some sort of anti sway device. Some weight distributing hitches include anti sway as part of the design, but many are a separate add on piece.
