Many thanks for all the feedback. I’ve been looking at other sources of the oil leak and agree it is probably the rear main seal. A minor drip at this point but will keep an eye on it.

I noticed some oil drips from my 2008 Yukon Denali over the weekend. Crawling underneath I noticed oil coming from the seal between what looks like the engine and transmission. Then I looked again and noticed what looks like a small chunk of the housing missing. I can shine light in this hole so...
My 08 Yukon Denali is doing something strange with its TPMS sensors. I switched from winter to summer tires a month or so ago, but since the TPMS has only been intermittently working. Sometimes the dash shows up numbers and all seems fine. Other times it flashes the TPMS warning light and then...
Hi,
My '08 Yukon Denali has developed quite a bit of sagging in the rear suspension (1-2"). I'm a bit of a noob, but believe this trunk has air springs. I notice that I hear a pump run for a short while when the engine is run, but even with this it's sagging. Both sides appear to sag by around...
I noticed today that I get a short hiss/white noise sound for a few seconds after I shut off the engine. Only noticed because I had the hood open and it stops within a few seconds. Everything works fine (including AC) so I'm wondering if it is normal??
Otherwise I assume I've a vacuum or...
My 08 Denali has had the common no start GM gremlins for some time, perhaps occurring every few months. But now on the holiday weekend I've had it twice in 24hrs. No start but other electrics worked.
I had the battery, connections and alternator checked at Autozone. No problems. It's going...
I've looked and looked but can't find the factory ride height for the Yukon Denali (2008)? I'm trying to determine if my 08 (recently brought) has been lifted at all.
Anyone know the measurement is on the 4x4 Denali? Perhaps height to the center of the wheel arch?
I have a 6.2L Yukon. It has low MPG, around 9.6 city. I checked the fuel rail pressure via OBDII and got 300kPa/43PSI. Does anyone have what it is supposed to be? Seems low to me.
I'm the proud owner of a 08 Yukon Denali. Great truck, but have few questions:
1) under mild acceleration there is a chirping noise from under the hood. No birds stuck there ;-). Is this normal or is some bearing going? Only got 26k miles on the truck!!
2) I'm looking to apply a tune to get...
