    Throttle Body Issues

    Was just looking at the TPS the other day and its riveted onto the throttle body. I would imagine replacement throttle bodies come with the TPS attached... this would then include the IAC

    2005 Yukon Denali No Drive Gear?

    Well shit the bed... tested the TPS and flushed the tranny to no avail. No codes and didn’t see any PCM problems. Took it to a good AAMCO shop here. They looked at it and determined it needs a rebuild. $2100-$2500 bones.... I really hope this sets me up for at least 2 more years without...

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

    Installed some Rockford Punch tweeters in the rear pillars. Had to bolt directly to the metal, but otherwise no other modification needed.

    rear noise help

    Recently been hearing a noise from the rear end during low speed turns both right and left, and even when backing out of the driveway. Not really loud but a noticeable “clunk clunk” to almost “creeeeek”. The kicker is that it only seems to do it after I’ve been driving it a bit, won’t do it...
