Does anyone have any suggestions to help get rid of the terrible drone noise that my Tahoe is experiencing after I installed a K&N fipk and Magnaflow cat-back kit? Right around 2000-2400 rpms it has a terribly loud in-cabin drone and quite frankly I cant tell for sure if its the muffler or the...

2003 Z71, 191,000 miles, no major issues yet (where is the wood to knock on?)

Does anyone know of a website/source for lq4 engine rebuild parts? I would love to find a comprehensive supplier for these parts.

Just re-read your post and since it sat for a long time (having plenty of time for the contaminated fluid to spread throughout he system), it sounds like your vehicle will need pretty much all of the rubber compnents replaced like I mentioned.

Sounds to me exactly like a contaminated brake fluid scenario, (contaminated meaning any fluid other than DOT 3 or 4 brake fluid). The most common culprit of contaminated brake fluid is power steering fluid being added to the brake master cylinder reservoir. Unfortunatley just a little bit of...

Thanks. Do you happen to know of any suppliers for slightly lifted coil springs for the rear. Like 1.5 inches is all I'm looking for. I would like to fing a coil spring replacement that is 1.5 inches taller and a little stiffer too so when I put a trailer with 200 lb tongue weight it doesnt...

Sorry for the fast add-on but if anyone knows of any 1.5" lifted coil springs available for my 2003 Z71 I would rather do that of course I would still need the lifted/extended shocks for the rear. THX

Don't know if anyone is still checking out this thread or not but here goes. I have a 2003 Z71 with front keys and Nitto 285's 188k miles and still running awesome (knock on wood). It looks ok, but I want to lift the rear up slightly, like 1.5 inches or so. Right now it looks like a prerunner a...

P.S. not trying to call anyone out, but these vehicles have "dry" intakes, not "wet" intakes like back in the good oil "R" motor days, so, leaking intake gaskets would NOT cause any coolant in the oil or any coolant loss at all, but rather a lean condition and usually sets off the SES light when...

What does the longer pin do for you? I have a 150k tahoe z71 and I am looking into getting the servo kit, but wondering if i shoul get the longer pin? Will it help hold the band tighter? Will it cause the band to constantly touch the drum and subsequently wear it out early? Any advice would be...

OK, I have done a lot of reading on the servo upgrade, I am almost ready to order a kit from oregonperformancetransmission but I dont know if I need the one that comes with a longer pin or just should get one without the pin at all? What arethe pros and cons of the longer pin? From what I...

OK, I will look into it, right now money is very tight/non-existant but I will start doing some research, thanks a lot.

What does the corvette 1/2 servo do for you? How do I get one and what servo do i use from a corvette and what is involved in installing it? My tahoe seems to forget what its doing when it tries to shift from 1st to 2nd, its seems like it tries but it hesitates to actually shift to 2nd, I have a...

I have pretty much the same questions, I am curious about upgrades to prolong logevity. If anyone finds anything out I would appreciate it. Thanks

At this point Im not sure if I need to replace the engine. When I start it up in the mornings it puffs out blue smoke from the tailpipe and clatters very loudly and briefly. I know about the "carbon knock" and how it doesnt affect anything. I dont think that what I hear is the carbon knock. I...

thanks, i have been doing research lately because I am at home sick from work. I would love to have michelins but the cost outweighs the benefits for me, does anyone know much about bridgestone dueler AT RH-S?

I have a 2003 Tahoe Z71 with a "Z" motor and it has 150k miles, I was wondering what motor would fit in my tahoe and what designation the 5.3 "Z" motor is anyway? I am new here to this forum and I have posted 3 times and have yet to see any responses, is it normal for not may people to respond...

Hi all, Im new to this site because I just bough a used 03 z71 tahoe and it could use some tires soon, should i just go back with the same wrangler at/s or try some new ones? Ive been looking at genral grabber a/t but they are a heavier load range and im not sure if that would mean a harsh ride...

Pressure testing the coolant system may reveal a leak or may not, these tahoes and trucks with the 4.8, 5.3, 6.0 V8's have a bad habit of leaking heads causing coolant to enter the oil system and sometimes burn it thru the cylinders. Pull your oil fill cap and see if there is a lot of...
