    Loose Seat Back

    Yes, I have a 2005 Tahoe and both seat backs move significantly. I can pull on the headrest from back to front and the uprights move about 2 or so inches. On the surface it appears that the problem might be wear in the upright gears or bushings. I will inspect and see if I can find anything.

    Buzzing Woosh noize behind IPC

    I found out what it was. The noise is the brake booster pump doing a self test at 10 mph after first start. I happened to stumble upon the information on alldata.

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Check these people!. I REPLACED CORRODED TAILIGHT HARNESS ON LEFT SIDE that connect to bulbs. connectors burnt! Check them people! I also decided to replace the cracked air filter housing on my 05 Tahoe but the crappy Dorman one that came in the mail was made of thin weak plastic. I returned to...

    Brake pedal slow return

    Hey Mike. Are you saying that you have experienced my exact issues in the past as well? it really seems that it may come down to the proper procedure for bleeding the brakes. I know, it seems dumb. I have done the gravity bleed as well. I will keep at it but it seems unnecessarily repetitive and...

    Cold air intake? Yea or nay?

    Dude, your link is bum. Save your money for an aftermarket catback or header and after exhaust made in Michigan. http://www.dynomax.com When you got the spare change then look to the flashy intake.

    Cold air intake? Yea or nay?

    To me it is not worth it from a cost to benefit standpoint. Oil contamination of the MAF and poor particulate filtration evidence is real. Also restrictions in airflow almost always happen only near WOT. Usually these systems are not needed. Therefore its mostly show. But its your money. In my...

    Missing Bose components?

    I would have to check the RPO code to verify if I have BOSE from the factory. Anyone have the code off the top of their head?

    Brake pedal slow return

    I tested the hydroboost accumulator and I get several brake applications with engine off before the brake pedal becomes stiff. I also have replaced the power steering pump twice. Each time I replaced the powere steering pump I have gotten a slight whine. But even after both power steering pump...

    Brake pedal slow return

    Hey everyone. I seem to have a series of rather challenging brake problems. My system is hydroboost on a 2005 Tahoe. I am having the following problems with my brakes: 1) little to no brakg action until the pedal is pressed about the halfway point. 2) Brake pedal is noticeably slow to return...

    Random thud noise from front of engine

    I got out to check the tranny fluid today and I noticed a rather odd thud noise. it is definitely coming from the front of the engine around the water pump /pulley area. but hard to say if it is those items. Its very random in nature and I don't see any rpm variation. I will remove the belts...

    Missing Bose components?

    I noticed yesterday that I got the Bose speakers as evident by the label on the door grill. However there does not appear to be a "BOSE" label on the radio head unit. Nor is there a subwoofer at the left drivers side rear speaker location in the back. I also looked under the cup holder and don't...

    Vehicle wandering - Thinking maybe control arm?

    Looking for some suspension advice here on the forums . My Tahoe's been aligned but every time I go back to the shop they say it's out of alignment a bit. Also the truck wanders a bit. So I looked at the bushings and they all look dry rotted. I have a 2005 so I guess its time to replace all...

    Clear Condensate Under Oil Cap

    Thank you for your input sparky! Would sending in a Blackstone oil sample be of any additional benefit? They test for trace amounts of antifreeze in the oil. This, and checking for the Castech logo would be the preverbial nail in the coffin if you will. What say you guys? Any other tips before...

    Clear Condensate Under Oil Cap

    Hello. I have a 2005 Tahoe with 5.3T engine. I have what I believe is the infamous missing coolant issue. Coolant recovery canister always empties over time. I have to keep adding 50/50 Dexcool to fill canister to the halfway point. I also can't find any drips or smell of coolant exterior to the...

    Intermittent rough idle and performance

    Hey everyone. For the most part the 5.3 liter engine runs great. However at times more often than not the engine has a very noticeable rough idle. Not so much rough on a consistent per revolution but rather a definite hard stumble or as of someone injected water into the engine at random and...
