    Stay chrome or Fade to Black?

    I like your chrome ones. I personally would only do black if you are going black out most of your trim as well.

    Lifter tick when cold? Berryman B12?

    So my 5.3L Tahoe with 170k miles has developed a loud lifter tick when the engine is cold. Once warmed up it is totally gone. This has been going on the past few thousand miles, so it may be related to my oil (I had just switched to Lubri-Moly Molygen 5w30). I've run Kreen through the oil...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I agree with you, just can't bring myself to lose the ground clearance (I bought the truck to drive in the snow). Thanks! I guess you are right about that! The clunk is definitely gone, I've been driving it all week and not a single noise.

    Best octane fuel for fuel eceonomy? (5.3L only)

    Well gentlemen I have enjoyed reading this thread and its responses, and I hope it continues. While a few of you dispute any changes to fuel economy when increasing octane, most people who have actually done it report an increase. To me 1-2mpg consistent improvement is fantastic. I have...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Gave her a wash. Solved my front suspension clunk, one of the upper control arm bolts was only torqued to 70-80ftlbs. I wouldn't have though that torque would let it clunk, but once I got it up to 130ftlbs the noise disappeared.

    22” CK375 285/45/22

    I paid A LOT more than this for a similar setup 3 months ago. Wish this was available then -- great deal, GLWS!!!

    Fuel pump rusted apart? Been there. Leaked gas for a week before I figured it out.

    Best octane fuel for fuel eceonomy? (5.3L only)

    This is exactly the discussion I was looking for guys. Unfortunately I do not have E-85 readily available near me (Maryland). Wish I did. Also because there are so few stations with it in my state the price is unreasonably high. I will try running 89-octane for a few tanks and see how I do...

    Best octane fuel for fuel eceonomy? (5.3L only)

    The owner's manual recommended a minimum of 87-octane. BlackBear performance is a pretty reputable company (especially on this board) that disputes that - they recommend 89 or higher.

    Best octane fuel for fuel eceonomy? (5.3L only)

    I've searched and read many posts, but I'm looking for more peoples' experiences. What octane gas yields you the best mpg in your Burb / Tahoe / Yukon? Which grades have you tried? Please only respond if you have a the 5.3L since the 6.2L requires premium. BlackBear recommends 89-octane due...

    FYI the tensioner is cheap and easy to install. I’d recommend most 2010+ owners going this route if they anticipate difficulty with the stretch-to-fit belt.

    New wheels

    I have these rims on my black Tahoe and I love them. But I have seen them on a white Tahoe, and it looked even better!!!

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Thank you for bringing that up! I actually read about that in an old post of yours, and got under and checked them myself. While they were not as tight as I'd like them to be, they weren't loose enough to cause a clunk.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    So I've been paying close attention to my "clunk" and I have noted that it only happens when letting off the brake when the suspension goes from loaded to unloaded. I've narrowed it down to my caliper (like my mechanic thinks) or my strut (likely the mount but I'd just replace the whole thing)...

    NNBS Cargo space?

    The NNBS second row seats do NOT fold flat with the cargo floor. They do fold flat with the third row seats, but this is not a continuous floor.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Thank you to everyone for the help. So to summarize... Light clunk noise when coming off the brakes (sounds like the front left). Both in forward and reverse. Don't have to touch the accelerator to hear it. Caliper sliders are lubed up and in great shape. Rotors and pads have plenty of...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Sway bar bushings are new. Struts and mounts are original with 170k on them... could be the culprit, but how to test??

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I checked them today and re-greased them. No issues.

    No tears, the look good, and I don’t hear any noises when spinning the wheels in the air.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    So paying real close attention, the clunk is when I let off the brakes after moderate-hard braking. Before I even touch the accelerator. Makes the engine mounts a less likely source right?

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    So the front diff mounts look solid - not sure how to test them. The motor mount on the other hand, seems like my driver's side is gone. Could that be the source of this strange clunking on acceleration?

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Will do. I took the front right tire off and everything on the suspension looked tight. Rotors and pads have tons of life left - I greased the sliders but everything was in good condition. What the heck am I chasing!!

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Good shape. They’re Delco replacements with I’m guessing around 50k miles on them.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Now that the skid plates are ordered, I'm hoping you guys can help me with the next problem. I have a clunk from my front left suspension area. It is obvious when hitting the brakes hard, then letting up. I have greased my slip yolk, but I can feel and hear this along the front left...
