Calling all GLP mechanics--gmt400 (Diesel_Tech where are you?) | |

 User ID: 85148208  United States02/01/2023 08:21 PM Report Abusive Post Report Copyright Violation | So, we get our health advice from GLP why not health advice of sorts for our vehicles. Quoting: Just Passing Through..... My old buddy Diesel_Tech who I normally asked has either changed his name or is no longer here. Ok, so here are the bullet points 1997 Tahoe Z71 2 door Obviously has 4wd and all the offroad goodies offered by GM. Now here is my problem. Whine/hum that starts around 20 and stays constant under load. The hum/whine disappears when I let off the gas. I feel a slight vibration in the gas pedal as well and it does seem to change pitch when I slalom the truck side to side at speed. Now, I know most will say its my rear end pinion or carrier bearings. I thought this too and it still very well may be but I emptied the fluid and no shavings or glitter indicating a rear end about to grenade. I changed the rear axle bearings and seals to rule them out and no avail. Basically my symptoms are a blend of wheel bearing and rear end. How the f--- do I pinpoint what it is? I can figure out how to repair just about anything on this truck but when symptoms match 2 or 3 possible problems....that's when things get a little iffy for me. I really hope its a bearing and I'm not stuck rebuilding, shimming, and correcting backlash on a new rear end. The rear end is RPO code GT4 which is the 30 spline 10-bolt with 3.73 gears and posi/locker Sort of reads like a bad front hub bearing. When you slalom the truck the noise changes. So if it changes, gets more quiet, when swerving left, check the left front hub bearing. If it gets quieter swerving right, check the right. thinking same....front hub bearing 48Panhead |

Quoting: Anonymous Coward 78809261 It wasn't supposed to be, we got past the algo. I hope he's doing well, that was a fun project. They mad about this. Caused SBF to be compromised. Wonder what they'd do if they knew we were responsible for manipulating the coin on black Sunday as well. 60k down to 28k haha. Exposing the truth, defeating the beast AI. Threw a major major wrench in their plans. Y'all don't even have a clue. They do though. Here's a hint at what's coming, God wins. |

User ID: 66609223 United States02/01/2023 10:57 PM Report Abusive Post Report Copyright Violation | since it hasnt been mentioned, check your motor/trans mounts too. ive had cars that had odd vibrations stop after changing the motor mounts.. the whole drive train can be out of alignment due to bad motor/trans mounts. Quoting: Anonymous Coward 80531705 Agree. Check if the noise changes going uphill vs. flat. Just exhausted my mechanical knowledge. A leak in my flex pipe also caused a humming sound until it blew a bigger opening. ...Loving souls, starving trolls... |

The rear end is RPO code GT4 which is the 30 spline 10-bolt with 3.73 gears and posi/locker obtain a cheap go pro clone with a strong mount and target the suspect areas successively with the mic opening not the lens aperture so much then drive until you deduce it This is actually sound advice(no pun intended) 40 bux and a roll of duct tape sure beat having your friend hang out the window with a screwdriver in his ear. best idea given in this thread, probably pinpoint it in an hour or two |
