    2007 5.3 year compatibility

    I too did a lot of stupid stunts in my youth and somehow came away unscathed :) My fastest drag car (see my Firebird avatar) 7.50 @ 182mph in the 1/4 mile, 1.08 sixty foot time, 4.85 @ 143mph in the eighth mile. This equates to a 0 to 60 mph time of .85 seconds. And, I piloted 4 different jet...

    2007 5.3 year compatibility

    I've often thought if our 2007 6.2 L92 gave up I'd find a 2010-2014 4.8 L20 to replace it. We have no need for the L92 power and would like to run 87 octane with its lower compression. L20 doesn't have AFM, does have VVT(good), is FlexFuel compatible(good), and an iron block(good). I think we...

    BW4485 (NR3) awd Transfer Case Rebuild?

    Yeah, like when I did the RMS job, I'll lower the vehicle close to the floor and use my HF lawnmower jack to pull it and install it. https://www.tahoeyukonforum.com/threads/rear-main-seal-job-pan-etc-07-yukon-denali-6-2.108334/page-2#post-1291151

    BW4485 (NR3) awd Transfer Case Rebuild?

    No, after watching some utube vids and seeing how easy it is too do, I'd do it myself for sure (I have a 2 post lift).

    BW4485 (NR3) awd Transfer Case Rebuild?

    07 awd Denali w/193k miles. No leaks but I think the chain is stretched. Has anybody rebuilt their Borg Warner BW4485 (rpo code NR3) awd transfer case? and did it reduce the Clunk? I've watched some videos and the job looks easy enough and parts cost is about $300. TIA

    Battery Suggestions

    Yes, and all things being equal, AGM batteries charge faster (less resistance) than wet cell batts.

    Low Oil Pressure when hot

    What @B-train said above. The VLOM or valley cover has O-rings that can get old and cause oil pressure loss. I'm changing mine (193k miles) soon as preventative mx.

    Oil pressure help

    Maybe a cracked oil pickup tube o-ring? Overfill the engine by 2 qts. With engine fully warmed up, park it nose down or raise the rear. If the problem goes away you've found the problem. If not, use 20-50 oil and see what results you get. In case you didn't know? The first # of an oil is an...

    My turn at front end rebuild...2013 Escalade ESV AWD

    @skpyle my control arms w/bushings and w/ball joints came with nuts, cotter pins, grease zerks. Yours don't? Our Denali is pretty much rust free. So, in hind sight I really didn't need the bearing hub bolts, or the camber/caster hardware kits. I could have easily reused the originals, but I...
