Run the same route again, but this time run 70 in the direction you ran 65 and run 65 in the direction you ran 70.

FYI, this is from a post by MS3DALE back in 2010. Subject: Do Not use Slip Yoke Grease from Bulletin #09-04-17-002C on 4WD Vehicles -------------------------------------------------------------------------------- GM Customer Care and Aftersales *URGENT - DISTRIBUTE IMMEDIATELY* DATE: November 4, 2010 SUBJECT: Do Not use Slip Yoke Grease from Bulletin #09-04-17-002C on 4WD Vehicles. MODELS: 2007 – 2009 Chevrolet Silverado 1500 Series 2008 – 2009 Chevrolet Avalanche, Suburban, Tahoe 1500 Series 2007 – 2009 GMC Sierra 1500 Series 2008 – 2009 GMC Yukon, Yukon XL 1500 Series Equipped with 4WD (RPO NQG, NQH) TO: Chevrolet/GMC Dealers ATTN: Service Manager and Parts Manager A new grease, part # 19257121 (in Canada, 19257122), was recently released for lubrication of slip yoke splines to repair a condition of a bump feel or clunk noise at stop or from launch on the vehicles equipped with 4L60 Automatic Transmission (RPO M30) and 2WD. Please see Bulletin # 09-04-17-002C for details. Do not use the new grease for lubrication of slip yoke splines on 4WD vehicles. The output shaft in a 4WD transfer case does not have a grease retainer to keep the grease from migrating into the transfer case and mixing with the fluid inside. The new grease is not compatible with the Automatic Transmission fluid used in the transfer case and can cause damage if mixed. Lubricate the splines on 4WD vehicles with Automatic Transmission Fluid, P/N 88861003 (in Canada, 88861004). Please refer to Bulletin # 09-04-21-003B for repairing the bump feel or clunk noise condition on 4WD vehicles.

Do not grease the yoke on 4x4. There is no grease retainer inside the tail end of the transfer case. Grease can leach into the transfer case and contaminate the fluid. Only ATF should be used on 4x4 2007 onwards.  

Seems Brian is either uninformed, or mistaken. I had a 1958 Corvette convertible that had a hard top also.

That would drive me crazy. Try blocking access on your router to see if it is indeed caused by hooking onto the Wi-Fi.

NGk does make the Delco plugs for these engines. Neighbor is WRONG, Mobile 1 filter is much better than the Delco.

If so, then I won't be buying GM for my next truck.

LOL, hell I went further than that on my original spark plugs on my 01. That still ain't high mileage. To the moon and back plus a couple of trips around the globe is where that club starts.

The "new" site has issues with the search feature at times. On the left side of the search bar there is a drop down that says "this forum". I check the box above it that says "all content". Makes for a little more searching on my side, but it does find most of what I need. I call it the new site because they upgraded the software about 4 months ago.

There a numerous threads on the exact same topic. The search bar is on the top right side and just about any question can be answered from there. Here is the first one I found and it has several others buried inside of it.

Make that 3 of us recommending an old one. Let me add one to look at -Snapper. If you can find an old one with the handle bar steering wheel and a 33 deck, grab it. If you can't find old iron, buy a Murray from Wal-mart. Run it for 5 or so years and toss it. They are cheap, disposable mowers.

PVC valve will NOT cause low oil pressure. Using synthetic oil will not cause oil pressure gauges to read a lower oil pressure than is actually present. Delco filters are not what they use to be, run a good filter like the Mobil 1. If the dealer did use 5w-20 oil by mistake, your oil pressure would be reduced.

What oil filter are you suing?

I have about a dozen Ryobi 18v tools and I wish I never would have went that route. The batteries don't last, I typically get about a year before they quit taking a charge. With that said, buy Ridgid from Home Depot. They have a LIFETIME WARRANTY on the tools AND the batteries! Here is a kit for $250.00 https://www.homedepot.com/p/RIDGID-18-Volt-Cordless-Lithium-ion-5-Tool-Combo-Kit-w-Drill-Impact-Driver-Circular-Saw-Reciprocating-Saw-Light-R9623N/300146409?cm_mmc=Shopping|THD|google|&mid=sXhADCnEW|dc_mtid_8903tb925190_pcrid_195274179091_pkw__pmt__product_300146409_slid_&gclid=CjwKCAiAt8TUBRAKEiwAOI9pAEBH4Bo9hMa_4x5SfcIz_ZKKzldJ5VmQ5LmH6-DEMp71fFbAxKx9whoChfUQAvD_BwE

I just read through the essay Chris and didn't see where you stated the year model. I would suggest that before you get all set on changing the oil pump that you do an oil and filter change (you failed to mention what weight oil you are using and what filter). If that does not change your numbers, then buy a mechanical oil gauge and see what the real pressures are. It could be a bad stepper motor, bad sending unit, etc.

I would contact https://www.texas-speed.com/ and get the delete kit and a tune. Here is the delete kit: https://www.texas-speed.com/p-7379-dod-afm-delete-kit-for-536062-engines.aspx

Many years ago I had this happen to the back seat side window of a 1979 Ford Super Cab. I drove up in front of my business, with the window facing the west. I was out of the truck about 45 seconds to a minute at most. I heard the pop of the glass and when I got back to the truck the glass was so hot it was smoking. I figured that the sun was at just the right angle, glass had just the right contour that made it act like a magnifying glass and it shattered from heat build up.

When I was a small child, I was playing with a marble on the dash of my grandmothers new 1970 Impala. Well eventually it found its way down the defroster duct. That damn thing rolled from one side to the other every time you turned a curve for the next 18 years...... You might get lucky and try accessing it through the cabin air filter and /or blower motor. I would adjust the defrost/heat/ac location settings hoping it would work its way to the bottom. If that doesn't work then you will have to start pulling the dash....

I would suggest installing termite shields between the concrete blocks and the floor sills. This will give you an idea of what they should look like: https://www.lowes.com/pd/CMI-8-x-8-Galvanized-Termite-Shield-Flashing/3014597

If you are scratching the paint when washing it, you are not washing it the right way. Washing it using the 2 bucket method will prevent scratches.

When my 01 started slipping while shifting, I changed the fluid and filter without any type of flushing and it corrected the issue for nearly 100,000 miles.

That would be the Florida Edition.
