    upgrade air intake tube

    I'm liking the homemade option! I was already thinking about that but the pic and description helped a lot. Finding some good stuff on Google, including the full post this pic came from. I was also thinking about buying one of the cheapies on ebay and just using the tube, but I think there'd...

    upgrade air intake tube

    2009 Tahoe, 5.3. I want to get rid of the accordian section of the intake tube, but I want to keep the factory air box and flat filter. I just want a smooth tube and to get rid of the resonator. I've been looking at Airaid, but $150-$200 for a plastic tube seems like a lot. Are there any...

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

    Stripped clear coat, sanded, and polished front two wheels. Did the same treatment to the rears months ago. They still look good so I wanted to do it all around. I stupidly don't have a before pic, but the clear coat was all blotchy and mottled. Faded and cloudy in some spots, but not...

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

    Been adding some lights over the last few weeks. Small light bar in front, surface mounted to top of bumper. Then in back I first did two flush mounts inside the bumper - they shine out from center quite a bit so I added a third surface mount just to the right of the receiver. Switch mounted...

    Ignition-hot source from a fuse?

    I’m trying to find an ignition hot source for the pink wire hanging out in the pic. It’s for the lighting circuit for an aux light switch I installed. (The relay for the lights is powered direct from the batt, so I can run them with key off). My plan was to use a fuse tap in one of the fuses in...

    Body side molding peeling back

    I got mine all off and tape remnants removed over the weekend. Everything came off clean except it took a small strip of paint off on PS front. I like the look off of it WO moldings so I think I’m going to leave them off. (Plus the thinner end of one of the moldings broke in removal). I...

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

    Brakes! Not today, but last two weeks I replaced front pads with semi-metallic and did a full fluid replacement. For pads, I'm a firm believer in semi-metallic over ceramic. Ceramics last longer sure, but I believe it's at the expense of rotors, at least on some vehicles. (In particular the...

    Body side molding peeling back

    Thanks guys. I'm going to remove them now. If we have sun in Feb in the PNW it's still not enough to get them warm, so I'll wait till summer IF I want them back on. But I may decide I like it without them. Good comment about taking careful notes and pics so I can locate them properly later...

    Body side molding peeling back

    I know this has been discussed in older threads, but I didn’t see anything recent for NNBS. I’m thinking about just removing all four of the door moldings. This is the worst one, but all four are doing it. I’m worried that they’re warping and putting them back with new 3M tape will just be a...

    Me too. '91 V2500, 383 that I built and OBD-1 tuned myself, 4L80e

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

    I did replace it. When I noticed this my first thought was, crap, fluid level is probably wrong. But after the fix, fluid level was less than 1/2 quart low. Fluid is very clear and light pink. I think I will still do a pan drop in the near future though

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

    Weird one for you guys - I had to replace my trans dipstick tube. Apparently I bought the truck like this. I knew it was loose, but I just assumed the bracket wasn't attached to the back of the engine block. I can't figure out a break like this would have occurred. Any thoughts? In other...

    MP3023 Transfer Case Grinding/Chattering

    "New" T-case from LKQ is in and rig is running and driving - no noise! $275, from a silverado with 119K. Install went pretty well except for the fact that exactly .5 seconds after I got it seated on the adapter I remembered I needed to install the gasket. Back down to the ground on the trans...

    MP3023 Transfer Case Grinding/Chattering

    Thanks for the info and vid link. seems like a plausible explanation. Do these problems continue to the MP t-cases of late 2000s? I think your 2002 would have been an NP261? Just trying to figure out if this is a systemic problem with the MP3023. I purchased a used one from LKQ today - 120K...

    Transfer case removal question

    no, exhaust wouldn't budge at at all. Yep, I cut the inside one. Then it just pivoted down so I didn't have to cut the other one. Got the case out no problem after that. I'll go to u-pull and see if I can find one on the ground. :cool: Thanks!

    MP3023 Transfer Case Grinding/Chattering

    Got the T-case out tonight and split it apart. I'm pretty sure the problem is with the planetary set itself. Everything looks good on the output half and spins nicely. But spinning the planetary by itself I hear the same grinding I heard when it was running. And there are ribs on the inside...

    Transfer case removal question

    My shot transfer case is coming out. I posted a couple days ago about severe grinding - further diagnosis just confirms that the noise is coming from the t-case. I started the removal tonight, but I've hit a snag. Main question: does the trans cross member have to be removed? I can't see how...

    MP3023 Transfer Case Grinding/Chattering

    Thanks, guys. I think that’s what I’ll do. I like rebuilding stuff when I don’t have to worry about trying to get it back together because I need to use it in two days. I’ve done engines, steering gear, alternators, starters, etc - time to try my hand at a T-case.

    MP3023 Transfer Case Grinding/Chattering

    Only the front wheels off the ground (by about six inches). And “shooting out” was a poor choice of words - put the plug back in right away when I saw there was fluid at the fill plug level. It would be an easy fix if that were the problem, but I don’t think that’s it.

    MP3023 Transfer Case Grinding/Chattering

    I was in 2wd. I did try auto and 4-hi while diagnosing on the road. - no change to the noise. But it went into all modes without issue. I can get all four wheels off the ground safely. I think I’ll do what you suggest. I’m beginning to suspect I don’t have 4wd. Front suspension needs...

    MP3023 Transfer Case Grinding/Chattering

    2800 mile family road trip over Thanksgiving week in the Tahoe. Ran great, really no major issues until about mile 2300 on the way home. Felt a hard shift from the trans (at least that's what it felt like) and from then on had a significant, impossible to ignore, metal-on-metal sound from the...

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

    Removed the tiny screen below the oil pressure sender. In the two months I've owned it I've never gotten a low oil pressure notice or any codes, but pressure was showing below 20 at idle and not even quite 30 at speed. Definitely a challenge getting the sender out with just removing the two...

    Slow cranking due to battery cable?

    I'm pretty convinced it was the cable to batt terminal connection that I showed at the end of the video. Many broken strands that weren't making contact at all, and the terminal used a set screw to hold secure, instead of strong crimp. The engine block terminal end looked totally fine, and no...

    Silverado Rims on Tahoe

    I love those 18s. When I got my Tahoe a couple months ago I was looking for a set of takeoffs with good rubber, that exact style. Didn't find exactly what I was looking for so I just got some nice, 90% new Coopers to fit my stock 17s. Next time I do tires, I'm gonna hunt a set of those down.
