    Spacers

    That's weird. My 01 had the 35s on it and I beat the bejebus out of that poor thing for a couple seasons with those tires on it. Got it to rub a few times out in the woods but never ever driving down the highway. I'd break out a tape measure and start checking stuff. I'd bet the offset of...

    Spacers

    Need to get rid of the wheels. The offset is wrong for that truck, spacers will be a band-aid on a stab wound. I had 35x12.5 pro comps on my 01 with just keys and spacers.

    Engine noise - like a pressure cooker - some coolant loss

    Almost impossible to diagnose over the interwebz. Gotta get some more info from you. Having a little coolant missing after changing out parts is normal in my experience. Motor runs through a few heat cycles and works all the air out, coolant level drops. Now, is it still leaking anywhere...

    2004 Tahoe rough start up

    How long after the new plugs and wires did it start doing this? Make sure all the boots are on securely with no cracks or splits. May even want to make sure the porcelain on the plugs isn't damaged. Check engine light on? If so pull the codes. How does it run once it starts? I can't...

    Transfer case problem?

    I've searched the web for about a week now, and had another mechanic look at it and we both say there's something not right here. When I say I used a pry bar to turn it, I used a 3 foot pry bar and a good amount oomph. Once the driveshaft was out, the front yoke spins by hand no issue...

    Transfer case problem?

    Picked up another 2001 Tahoe with 88k on her. Decided to swap all fluids. Then had this happen, while doing the transmission filter, I went to remove the front driveshaft and to my surprise, I couldn't move it. I put the trans in neutral, still nothing. Put the t-case and trans in neutral...

    Tcase took a dump?

    rockola1971,,,I believe you nailed it...no pump rub, still has the "anti rattle" clip...no shiny spots...nothin...BUT, i placed the two halves back together with no chain installed...front output sounds like its filled with sand...sure enough, roller bearing fell apart as soon as i seperated the...

    Tcase took a dump?

    So, I got under there and pulled it out. Then tore it down, checking and bagging stuff as I went...only things that jump out at me are the clutch housing is all burned (different blues, yellows, and blacks)...the needle bearing in the case had a roller or two fall out as soon as I touched it...

    Noticed a rusty orange color inside oil cap and down filler tube.

    As long as your truck doesnt have a brand new motor or very low miles...completely normal. Especially if you dont get up on the highway often, or up to running temp often Engine gets hot, then cools off, moisture inside the crankcase condenses into water, mixes with oil, and then vents off once...

    Won't start, replaced fuel pump, still won't, Code P1626 - new owner with dead truck

    Bypass the passkey system and be done with it. 10 minutes on google and you'll learn exactly how to do it. Done it about 30 times now...and the worst side effect is the security light will stay on or flash...but the truck starts everytime.

    won't go into gear right away

    Sounds to me like a fluid issue.... I'm not a transmission guy, but Ive blown enough of em up and messed with em long enough to have a decent idea of what makes what work. Before anything else, is it the factory unit? Maintenance schedule? Reason I ask, is because as transmission fluid ages...

    Tcase took a dump?

    So, long story short, took truck for a test ride after readjusting some stereo stuff...noticed that it had a real bad stumble/rumble but only when I got into it a little bit. Get the truck home, back and forth in the driveway and get a god awful squeaking sound from under the truck. Put it in...

    Cam and stock exhaust

    ..Throwing a cam in and leaving the exhaust stock is essentially eating 6 viagra and watching golf... You will want something better flowing...stock stuff isn't actually tooooo bad, but not good enough, plus, a little roar/rasp is a nice thing with a little cam talk. BIGGEST thing, not sure if...

    862 heads

    I know a few guys who have done it...mixed results. The 862 heads are smaller on all fronts and dont flow as well as the factory 6.0 heads. If it were me, spend the money on getting the factory head reworked. Just feel like its the 305 heads on a 350 thing again every time I hear about it...

    01 Tahoe bogs randomly

    So, not sure if anyone cares...but I figured it out. Cleaned MAF didn't help, removed and cleaned throttle body, didn't help. Filled up with Mobil gas and drove the wheels off her, didn't help. Changed fuel filter, didn't help. Whole time there were no codes mind you...what a pita. Finally...

    01 Tahoe bogs randomly

    So, driving the tahoe around the other night with the wife...leave a red light, get up to about 15mph and the truck falls on its face...It never stalled, never had a wicked drop in rpm, just a real noticeable loss of power for about 20 feet then back to normal...Tried for about 20 minutes to get...

    2003 Yukon losing ~3 quarts oil over 3k miles

    Before you go panicking over a rear main seal job, check you oil pressure sender at the back of the intake manifold...lots of guys have gotten the trans out only to realize that their weekend was wasted because of a $25 part...I replaced 2 on my truck...and about 40 on other tahoes/yukons. the...

    2000 Tahoe Water Pump Replacement

    If the hoses arent spongy Ide leave em alone...definitely get a new thermostat...buy a good one, seen lots of issues arise because somebody wanted to save $4...as far as coolant goes, pull the petcock on the radiator, drain it all the way out, do the water pump job, fill with 50/50 when all...

    Service 4wd help

    Code 42? What year is the truck? My 4wd has always been touchy. Had similar problems with mine and ended up throwing a new encoder motor and the front axle 4x4 actuator. Both were really easy jobs in the driveway. Truck goes in and out of 4hi real easy, 4lo is still touchy but hey, I RARELY...

    02 Tahoe Heavy Misfire P0300

    Couple of questions. Any smoke out the exhaust? Any coolant in the oil? What do you fuel trims look like? Any vacuum leaks? Multiple reasons for it to run like that. If the p/o has done all that work and still didnt fix it, its either deeper in or really simple...funny how things work like...

    erratic voltage gauge in 03 yukon xl

    How was the battery tested? Just because it shows 12v doesnt mean its good. Pull the alternator and have it tested too. Check your cables for tightness, make sure the alternator cable is tight and the plug on the back is too. Takes 10 minutes for a first timer and if it ends up being bad...

    A/C Always On?

    Not sure what you mean by the compressor is on even when the truck is off...even if it has power to it, its not doing anything, so not sure how it would've drained the battery...secondly, do you have your air set to the windshield at all? if your running the truck with air on the dash at all the...
