    Water when raining

    Clean out the sunroof drains. Very common.. Or sometimes the drains tubes separate from each other where there is a "fitting" like a T or a 90* You'll have to remove enough stuff to inspect them thoroughly

    Issue After Brake Rotor & Pad Replacement

    I always replace the hoses when I do calipers.... It's good practice as it's hard to diagnose a collapsed hose/line

    Battery dying over night

    I know it sounds simple, but make SURE your battery is good. Load test it ! Double check both battery grounds and positive cable to starter & fuse block. If the cables are original they may be corroded internally

    Would it make any sense to install a 1-2-BOTH-OFF switch for a dual batt setup?

    The one note about the Detroit TrueTrac that I don't like is that you can't use synthetic gear oil. The synthetic additive act like a "posi additive" and screw it up. You have to use old fashioned 80-90w mineral gear oil without any additive. I own 3 detroits in my ford aftermarket built...

    C0590 Suspension Code Help - SOLVED

    That happened to me on my 2014 several years ago !!! Went out for my test drive. No more suspension codes. Was just a bad shock Rides much better. The 20" rims are better too. More rubber !!!

    C0590 Suspension Code Help - SOLVED

    Thank you for that info. It's the electrical side of these sensors that I'm just not that versed in (body junk) I did stay up most of the night working on this 2013 REAR Put new powerstop tow brakes/rotors/pads The M'fr caliper bracket bolts were about welded into the rear though.. And no way...

    Aftermarket HD Rear Coil Springs - My Experience

    Looks Good ! I'm actually taking off my 22" wheels that came on my 2013 denali and putting on the 20" wheels that were stock on my 2014 denali Big difference with less sidewall on the 22's.. I'd think if you carry quite a bit of weight (enough to need better springs) you would really hate...

    Would like to address slightly soft shifts with HPT

    It take a while for the adaptives to learn... Sometimes up to 200 miles. Best to change filter/fluid and then to an adaptive reset procedure OR with HPT you can do a "clean/purge" procedure so the trans knows to RElearn the adaptives due to a service

    [SOLVED] 2012 6.2L Yukon Denali XL 172000 miles? Need help and cannot figure this very random problem out.

    Probably a good idea to replace the thermostat as well. A lot of temp codes can show up with a goofy thermostat.. Just not overheating, but "underheating"

    Front Axle Seals replaced...still leaking

    This is probably the problem as you've stated how careful you were. I'm ocd too about stuff... Been proven time and time again that alot of branded parts are counterfeit on Amazon. I bet if you bought them local or on rockauto, you'd get ones that are packaged "similar" but not exact .. and...

    I forgot what a PITA it is to drop the transmission pan NEED HELP w 2 Manifold Nuts

    Well, I tried a different stud extractor after I had to cut the nut/stud combo off. And it worked. So I don't have to pull the whole manifold. I was able to install a new stud on that crazy one. Then all new nuts of course. Pulling the driveshaft, Oil filter, sway bar and heat shield gave me...

    I forgot what a PITA it is to drop the transmission pan NEED HELP w 2 Manifold Nuts

    Crazy thing is this Yukon is spot free/ rust free in and out !!! I wonder if some tech was mad and tightened it to 140 lb ft when it was serviced last !!!!

    I forgot what a PITA it is to drop the transmission pan NEED HELP w 2 Manifold Nuts

    Well... The problem of the trans pan removal/install is done I had to remove the driveshaft, sway bar, oil filter to get access to the 1 remaining nut on the left side... Had to cut/grind it off including the stud to get the exhaust down. The 1 remaining nut on the right side I was able to...

    I forgot what a PITA it is to drop the transmission pan NEED HELP w 2 Manifold Nuts

    Its the 3 manifold nuts at the flange that have to be removed... Not the back part of the exhaust When you pull down the Y pipe with cats, it gives you enough room to remove the pan.. My 2014 was definitely not this frickin difficult.. But I suppose that was over 6 years ago. Then I did...

    I forgot what a PITA it is to drop the transmission pan NEED HELP w 2 Manifold Nuts

    I tried getting the trans itself up a bit.. I even removed the mount hoping to be able to wiggle stuff around... The trans just tilts the motor with it... Only gives about another 1/2" at most. Not quite enough... Maybe on a RWD it would give enough ? So I soaked the 2 remaining nuts again...
