2007 Z71....I am starting to notice a thumping noise which seems like it is coming from my front passenger wheel. It is most noticable at low speeds while coasting to a stop or braking. I'm planning on rotating my tires to see if that helps. My research says it may be a broken belt in the...

When I am backing up and get within range of something, my parking sensors will beep once and the yellow light will come on. As I get closer, the second yellow and then red. I will still only get that one original beep though. After parallel parking for a bit, I got back in, put it in reverse...

Temps here are now dipping into the 20's and 30's. About 3 days ago my drivers side window makes this horrible squeaking noise when I roll it up and down. More when going up. It sounds like it is the glass rubbing against the weather strips and not a motor (I hope). Anyone else have this...

OK, just sold my 99 tahoe and bought a used 07 Z71 from dealer that is still under factory warranty...but this morning, no cruise control or steering wheel stereo functions at all. The light on the steering won't light up or nothing on dash to indicate it is on. I checked what I thought was...

Well, I have traded in my beloved 99 tahoe for a newer version. I will be moving into the 07+ catagory. Snagged an 07 LTZ z71. PS...they are giving them away right now. I thank all of you who gave me all the great tips and insight for the time I've been here. Keep up the great work.

What a way to start the morning. I made a morning run to the local Wal-mart. When restarting my truck, I heard a clacking noise. I noticed that my idler pulley seemed to be wobbling a bit. Took a chance to get to my office and did, but the serpentine belt broke 1/2 way there, but made it...

Went on a trip about 2 weeks ago of about 400 miles, so I had my front 2 tires balanced before hand. Balance was good, but once I got home, it seems as if my right front is out of balance again. No pot hole hits, tire pressure good, recent alignment. I have had this problem a few times...

I attempted to try and get my bank 1 downstream 02 sensor off yesterday. Of course, Chevy decided to make it hard on us and put the sensor on the top of the pipe, next to the frame and heat shield, making it nearly impossible to get a wrench in there. Has anyone replaced these and is there a...

Does anyone know which side of the engine is the bank one (#1 cylinder). Going to get my cat replaced and that is the one throwing the P0420 code. Just want to make sure they replace the right one. I plan on doing both, but not at the same time.

It looks like I am the first with an a/c problem this summer. What is wrong...End of last summer, my a/c started to fade away. I assumed I may have had a small leak somewhere, so yesterday I put in 1 can of leak finder/sealer. I do not see any leaks. Ran it for about 15 minutes and still...

I am in the process of deciding upon replacing my cats with a direct fit system. The one I've been finding is magnaflow. I guess I'm wondering if these things really bolt on to the existing headers/muffler as described. I got under it the other day and there seems to be quite a bit of stuff...

I've been dumping money into my 99 about every week to keep her running smooth instead of spending the cash on a new car payment. It has been running great, but all the sudden, my SES light came on again. It happened as soon as I drove about 200 miles and fueled up. Gas cap is on tight. I've...

Does anyone know about how much gas is wasted due to Catalytic converters? I just read that it can be around 30%!! Can anyone confirm this? I would never have mine removed, of course.:shhh:

I installed a new head unit and all the sudden, the lights on my headlight switch cluster doesn't work. The harness behind the dash seems to be correctly connected. Is there a fuse on this or did I possibly break a bulb when removing my dash piece. Is there any kind of wiring to the stereo...

Is this a waste of money? I have 161,500 on my 99 4x4 LT. I was considering taking it to Aamco and having them completely flush the fluid, change filter and gasket and replace with synthetic. I have a very slight slip when shifting and was hoping this could help a bit. Plus it's never been...

Does anyone have any idea if the mounting holes on the '97 spare tire bracket/carrier are the same as the '99? I would assume so, but you never know.

I am going to install a new amplified sub in the rear cargo area against the back seats. I'm not sure of the best place to run the power supply cable through the firewall. Any suggestions? Easist place prefered, but I want to do it right though too. I'd like NOT to have to take too much of...

I just installed a new stereo yesterday, and just noticed that my rear door speakers are not working. I connected all wires, except for the blue amp wire (no amp yet). All other wires are accounted for and have been hooked up to the aftermarket harnesses. There is discussion of a stock amp...

I just installed a new stereo yesterday, and just noticed that my rear door speakers are not working. I connected all wires, except for the blue amp wire (no amp yet). All other wires are accounted for and have been hooked up to the aftermarket harnesses. I have found no settings on my radio...

99 Tahoe LT 4x4 5.7L I've just turned 160K miles and have recently been hearing a whining noise coming from what seems to be the front of the engine. I replaced my alternator about 30K ago, so I don't think it is that. The noise seems to be coming from lower in the engine. It seems to be...
