Took the Yukon to work today instead of the company truck. Smelled of warm brakes on the back passenger. Upon further inspection the slide pins were bound. Looking closer the stupid little rubber boots are darn near disintegrated! I think I redid these brakes 2-3 years ago completely with new...

Dug further into the Hayden fan controller option. The main reason I wiped this off at the moment was I intended for all speeds to be completely automatic. To do this I would need 2 Hayden 3653 units. See unit here...

Finally tackled the drivers heated seat. It was the upper that burned out. We got hot buns now, will see how long the Amazon seat elements last! Such a sad world we live in. Id rather rest my luck with junkyard used OEM parts over brand new aftermarket garbage. Local stores are loosing my...

You are correct. I did think about this, and ultimately may do it as well. Only reason I was going to do the switch for now is I plan to add some A-Pillar lights to aid with plowing at night. I had hoped to get those done before this winter, but it got cold fast as it always does....

Normally I don't like doing stuff like this, but with my only other option being to "re-tune" the computer, its just not worth it. I have been having issues towing and plowing with temps mainly due to the electric fan setup and its "triggering" parameters in the computer. By the time fans are...

Picked up 3 of the best looking junkyard OEM coils yesterday. Put another on last night, so far a total of 3 I have replaced with the junkyard units. All have great arc now when pulling the boot except for 1 remaining gray one. Will swap that one out too but the Yukon made the 2 hour trip with...

I too was sucked into the dud steering box and pump debacle from crap local stores and Rock Auto. I've swapped gearboxes twice and both rebuilds have IMO excessive play. I've swapped steering pumps as my original rotted out (should have done more to save it). Both pumps I installed struggled to...

I'm sure, I would like to know what manufacturer the gray ones are from. It would be very tough to relocate, would need coil harness extensions, plus longer plug wires as they mount directly on the valve covers themselves. So you can still get AC Delco units, issue is when in a bind, nobody has...

The 4.8 is a good engine just as the 5.3 and 6.0 of that era, would be a reliable rig if maintenance has been done. Check warm oil pressure, common the pickup tube O-ring gets brittle and cracks resulting in lower oil pressures. Some of the earlier GMT800s have what they call piston slap on cold...

Our small diesel fleet at work is still running all compliant emissions equipment, with our oldest truck being a 2012 Silverado 2500HD Duramax with approximately 250K-miles. Others are newer 6.7L Powerstrokes. Just not worth the potential issues for a business in my eyes to remove them. If I had...

Spent some time last weekend with my annual Fluid Film undercoating. Yukon is coated and ready for its 6-month salt bath: I also spent some time checking spark plugs to see if a visual identified could be seen. Even my newer scanner doesn't have cylinder balance or misfire checks. I would...

With a solid week of constant rain or the threat of looming it decided to tackle the trans filter swap and flush. My initial plan was to just flush it since I had a shop do a filter back when I got it. But I just needed to look inside for piece of mind at just shy of 202K on the clock. Getting...

I agree, always gave me PMD heat soak fears, but to be honest I have only had a single GMT800 coil fail in my experience with them. One thing I didn't realize was there are 2 types of coils for these engines square and round. I guess that is where the difference in wire length comes from...

Very clean. I wrapped mine on the '94, unfortunately being my plow truck it vastly expedited the rot and I ended up replacing the downpipe barely 2 winters after.

Nice on the little Duramax. We have 2 of the 4-cyl turbomax half-ton trucks here at work. Both around 60-80K in miles and bought used at the same time. We did have a valvetrain failure in one this past summer, and a fuel pump failure in the other. Both were not cheap outcomes!

Nearing 202K-miles this past weekend. The idle seems to have a miss or shake to it every so often, but to be honest has been this way for a couple months now. Got a new issue arising from the Yukon that started about 3 days ago. During cruise and TCC locked, I can feel a "buck" that at first...

Finally bought the amazon element set, its been sitting in my mudroom for a few weeks now. Need to get some time over the next week or so to get it installed with the weather turning here!

I'll get a set off Amazon, worth the risk I guess!

Anyone have any experience with eBay or Amazon aftermarket replacement heated seat elements? How about the Seat Shop? My drivers seat in the 05 Yukon will trip out almost immediately. It has a dual button (back only, or back and butt). No matter the selection it trips off leading me to think the...

Had an issue with the Yukon yesterday. A bit late to a golf tournament, part way there the CEL began flashing. Could tell we had a miss and down on power. Ended up parking it and caught a ride with a friend. Codes retrieved were P0306, so cylinder 6 misfire. Today I went to Napa and got a coil...
