Well I just got the truck back from installing (again a TrueTrac and 4.10). The guy said that the guy who installed it before was way off on the adjustments. Thats where my previous noise was coming from. Now that everything was installed by 20 year experinced person I am hoping my noise is something else. Anyways when you get going and are at any speed (Ive kept it at around 30-50mph since they are new gears) if you let of the gas the noise stops but here is the weird part. You slightly press the throtle and the noise comes back you let of the throtle and the noise takes about 3-4 secs. to go away almost like if there is a solenoid or something that is opening and closing. What do you guys think still gear noise or maybe something in the trans. I have not recalibrated my computer to the new 33inch tire and 4.10s. I bought Genuine Gear. I have read that richmond gears make noise even if adjusted right. Can it be the same for genuine gear or my noise is something else maybe in the tranny or driveline. Thanks
