    Oil pressure on 07 Tahoe?

    That is scary. My one experience like yours was with a 78 Buick. The difference was I ended up pulling the pan and installing a new oil pump afterward as that mess that came out also clogged my oil pickup and resulted in low oil pressure a week after the oil treatment/flush. Turned out the...

    BW4485 Transfer Case Rebuild - Questions..

    I haven't rebuilt a transfer case yet but studied it on my last generation Escalade. I don't think you need a chain/sprockets unless you suspect chain stretch. From what I understand though there is a viscous coupler in these transfer cases. I would think that is the part you'd want to replace...

    Changing break fluid.

    I flush mine about every 2 years, I run about a gallon of fluid through the system to get all the snot looking fluid out of it. I don't worry so much about calipers or master cylinders getting corroded, my main concern is keeping the ABS module corrosion free. That is an expensive...

    07 08 calipers different part numbers?

    Yup, I did it on my 05 and it was pretty substantial in the stopping department. Now I just need to see if I can upgrade the rears on my 07 to the 06 brakes. The 07+ models went to a single piston caliper and smaller rotor. Not sure why they did that. My 05 felt like it stops faster than my...

    Bad lower control arm ball joint?

    Glad you figured it out. I rebuild the entire suspension on my 05 before I got rid of it for my 07 and I'm about to start over again. Ball joints are a PITA but doable if you have a ball joint tool. I ended up on the 05 just getting whole new LCAs based on how the UCAs looked (bushing shot)...

    Left rear Brake

    I noticed this too. Never had this happen to me before moving to a snow/salt use area. It sure is rough on everything under the hood and body.

    I need to change cooler lines. Need Advise

    I'm thinking of doing the same. I've had factory lines leak before but never had the cheaper hose alternative let me down yet. Just some barbed adapters and high pressure hydraulic hose and you're set. From what I understand the factory lines all seem to leak from the crimps where the...

    Pre detonation knock.

    You sure you're experiencing detonation? Maybe an exhaust leak instead? If you had detonation the PCM either stock or aftermarket would retard the timing and you'd see some horrible fuel economy compared to what you're used to. Have you seen a noticeable drop in mpg?

    Another new owner!

    Welcome aboard. I miss those two door Tahoes from the past. Several years ago I was shopping for a 99 but couldn't find one that wasn't beat up or rusted out, I gave up and wound up with a Trailblazer LTZ as my first SUV. I miss that SUV at times.

    New to me 11 denali.

    Very nice. I also just joined the club last week when I upgraded from an 05 Escalade to an 07. Fully loaded. I almost bought a 2010 Escalade in that gray color of your Denali, it was a beautiful vehicle but was missing some must-have-for-me options. No moonroof, no heated steering wheel, and...

    wonders and rides rough

    I just finished rebuilding the entire suspension on my Escalade. The part that made the most difference in my ride was the upper control arms. The bushings were pretty shot after only 90K miles. Lower control arm bushings still looked pretty solid compared to the UCAs but I replaced them anyway...

    Hey guys question about emissions

    I had the same issue with my old winter beater, a 98 Oldsmobile. Had a dead battery and changed it, then drove it around for about 150 miles and still had 3 monitors not ready. Probably needed to sit overnight to cool off to ambient temperature to get the remaining monitors to run through the...

    New 2013 Yukon Denali-thoughts?

    Congratulations. Seemed like a pretty good deal to me.

    what is the best fuel injector cleaner?

    I've been using TC-W3 marine oil in my gas for a couple of years now, it's pretty cheap at $13/gallon at Walmart and you use around a 1:500 ratio, roughly 1 oz per 4 gallons. Found this thread a couple years back and decided to give it a try. I used to use MMO several years ago and always...

    Installed Flowmaster 70 Muffler

    I'm running the Magnaflow cat-back on my 6.0L Escalade, zero improvement in fuel economy. The stock system seems to flow pretty well on these trucks despite how heavy the muffler is. I generally replace the exhaust system on every vehicle I buy, mostly for a little volume and small economy...

    07 Brakes Screeching

    Considering these are brakes from the dealership I'm surprised. I had this problem on my 05 after I performed a brake job as part of upgrading the brake system, new calipers, rotors, and pads that came with the rotors. They were supposed to be quality ceramic pads but I have to wonder when they...

    New to me 2010 Escalade with some things I had to fix

    Seems like a great deal to me. I'm starting to shop 09-10 models and a clean one at that price is hard to come by here in the mid-atlantic area.

    New 2013 Yukon Denali-thoughts?

    I don't know that the dealer will go that low in price, but you can always look at gap insurance if you're financing it. I bought gap insurance once on a vehicle and it was actually cheaper to get the gap insurance than not get it. The bank gave an extra half point off the loan if I bought the...

    New head unit with Bose

    The easiest option would be putting a factory nav in. No interfaces needed, plug and play. Only a Tech2 to program the VIN re-learn for the theft deterrent system and a $20 eBay GPS antenna to mount under the dash cover. The dealer should be able to reset the theft lock for around $100 if you...

    Advice wanted on replacement transmission

    The 4L65 should be in any truck/suv that has the 6.0L engine, Escalade, Denali, the 6.0L equipped trucks. It is the same trans case so bolting up shouldn't be an issue. Also the RPO code. It should be M30 for the 4L60 and M32 for the 4L65 transmission.

    I hate winter

    You live in salt, ugh. Think you hate it now, wait till you start working under a 13 year old truck that lived in salt country.

    Fan won't blow on speed 1

    And I've always gotten my blower motor resistors from the salvage yard. Replaced the one on my 98 Aurora last year, $115 from the local parts stores, not much cheaper on-line. Not sure what the truck version of this part costs new. One hour of my time at the salvage yard and $7 was what I...

    Max 4lo speed

    I can't tell you for sure as I'm in an AWD now so no 4-Lo. When I did have a GM 4WD SUV though I don't remember getting it much above 20 mph before I was up around 4000 RPM in OD. The gear reduction is pretty substantial.

    Windshied Washer Fluid Disappeared??

    I thought the fluid reservoir was on the driver side, might be wrong though. Did you look at the hose where it attaches to the wiper arm? It seems to be a mild stress point that would move/pull when you open the hood. Outside of that I'm thinking that frozen fluid ruptured a rigid plastic line...

    03 Denali Front Differential carrier bearing going bad

    I've researched it a bit on the net and it doesn't appear there is anything that can be done other than a normal rebuild. One of the common failures is the tab that holds the adjusters where you set the lash, surprisingly I came across no improved pieces.
