    130k miles require valve ajustment?

    So what was the issue? Are the lifters bad? Maybe alternator noise?

    Good price! Now you have peace of mind knowing your systems are clean and in good working order. Good for many more happy miles.

    2016 Tahoe 45K Mile Service

    I flushed my brake system at 45k (3 years) and it was pretty dark. Brake fluid gets nasty as it absorbs water and from a lot of heat. I posted a pic: https://www.tahoeyukonforum.com/threads/don’t-forget-to-flush-your-brake-system-3yrs-or-45k.101226/ Trans fluid I had changed (dealer dropped...

    Time for brakes

    Flush the fluid at all 4 for sure. It might look ‘good’ but it’s not after all those miles.

    Time for brakes

    I flushed system and used OEM rotors and Wagner Quietstop pads. The orig pads were still fine for all but 1 of 4 pads, which was worn to nothing- must have been a sticking slide. If that wasn’t there pads still had a ton of life left. This was at 60k

    2015 Yukon XL brake bolt torque specs

    Nobody can confirm? I did front rotors and pads today-ended up using 74 ft/lb for caliper pin bolts and ‘as hard as I can’ for the caliper bracket bolts. My torque wrench does not go up to 170, but they are on tight ....had 60k on them. One of the four front pads was worn to 1mm rest maybe 4mm.

    Looking to upgrade brakes

    Just did my fronts today. Got OEM rotors and Wagner ThermoQuiet pads. They work fine. Had truck in dealer for trans pan drop and filter change (60k on truck) and they said front pads had 1-2mm left.... must be dragging calipers cause only 1 of the four front pads was that low. Rest had a...

    New here - 2015 Tahoe Question Re: Sound during acceleration

    I had this on my 2015 Yukon Denali and they replaced my transmission . Early 8l90 units had some kind of clutch clearance issues. No longer does this for me. Changed trans at 15k miles.

    2015 Yukon XL brake bolt torque specs

    With online searches I am seeing different torque setting numbers for caliper bracket, caliper guide pins etc to replace all 4 brakes. Does anyone have 100% correct brake component torque specs for a 2015 model. Example below does not seem ‘for certain’...

    2016 Tahoe - transmission fluid change?

    I’ll Had it done today. Pan drop, clean pan/ magnet, filter and 7 qts fluid. They used Mobil1 LV HP. Tech gave me couple pics. He says the magnets look spot on from the other 8 speeds he’s serviced . Also said fluid was a little dark, so I think this was a good decision to have it done -...

    Looking to upgrade brakes

    I think the stock brakes are pretty great. You guys really think there will be that dramatic of brake feel increase? Is have a 2015 Denali - not sure if regular Yukon has lesser components. Just seems like a lot of expense to change calipers and lines with a solid stock system. I don’t...

    2016 Tahoe - transmission fluid change?

    Update Dealer called me after being contacted by GM. They will do pan drop, filter change and fill for about $370. Will take couple hours due to detailed procedure needed - fluid has to be in designated temp range. It’s about 7- 8qts replaced. Guy from dealer says he’s personally a fan of...

    2016 Tahoe - transmission fluid change?

    I’m sure it’s safe, but dealer won’t do it. They will only do drain and fill . I don’t get how GM has a service schedule and then dealers won’t do it. I get the 8l90 is troubled... I used online chat with GM to ask what do the GM factory techs say.... They said to do filter and fluid...

    2016 Tahoe - transmission fluid change?

    So get this- I’m taking my 2015 Yukon in for trans fluid exchange. It has the 8l90, so no pan drop. They won’t do full fluid exchange (dealer). Just a drain and fill. I don’t think dealers want to touch these 8l90’s...though 45k is severe fluid interval, tech said dealer won’t do filter...

    Rear diff- 2015 Tahoe

    I did the job on my stomach/back without lifting truck. Yes you can remove cover without removing that crossmember. Used 75/90 Amsoil in both. https://www.tahoeyukonforum.com/threads/2015-yukon-change-both-diffs-oil-and-transfer-case-fluid-early-on.94453/#post-1128531

    Totally disgusted with my 15 Denali

    I’ve glued all appliqués back on with either gorilla glue or epoxy. Yes , it’s a joke they use shitty double sided tape. My gps antenna failed as well. Replaced under warranty .

    Odd noise. Transmission?

    When I’m in Auto or 4WD there is a slight hum when I accelerate as well. I hear the transfer case working . I think this is normal. If it’s loud or grinding, you have issues.

    Don’t forget to flush your brake system - 3yrs or 45k

    That sucks , sorry to hear they rounded off and were frozen. Next time spray some PB Blaster or other penetrant on them the week before you plan to do it and that will help dissolve any corrosion locking them up. I noticed they were really tight - was first time they were cracked open. I...

    . Be careful with open end wrenches and bleeder valves. Can round them off easily. I cracked it with the box end, put Mity Vac or tubing on bleeder, then open rest of way with open end . It’s easy to round bleeders, so I would recommend use/ start with box end.

    There are tons of descriptions online. Basically suck old fluid out of reservoir. Refill with new. Bleed brakes starting with caliper farthest from reservoir- bleed until fluid runs clean. Several ways to bleed - helper pumping pedal,vacuum bleeder, pressure bleeder. Search - how to flush...

    The fluid breaks down from heat. Brakes get Hot! Plus, I think air does deep from the reservior cap- minute amount over time.
