    Most additives allow the clutches to slip to avoid chatter.
    If your rear end is howling than an additive is not going to help . Most likely the Gov-Loc is dying a slow death and the small part are wearing down and getting caught in the bearings and wearing them out with every turn.
    If you need it to last as long as possible than put some 140 weight gear oil in along with the GM additive and drive easy when turning sharp corners ( as in little to no throttle ).

    Gov loks take no additive. Do not use a friction modifier.. Just put in 140 wt oil and change reguarly.

    Very true ! Just wanted to give him advise on making it last, if it is possible . If the G/L is wearing out than the additive might help the clutches slip instead of grip like a functional G/L.

    Ahh yes I see the method to your fix. The care and feeding of a gov bomb:D
    They have to be carefully prepared so they will detonate properly.:laugh:

    Ha ,ha !
    I would say that GM/Eaton should be ashamed of such a creation but the designer probably got a bonus due to the amount of additional Gov-Bombs sold throughout the years ......

    na looked good few months ago. when at speed if you load and unload the drive line with the gas pedal it makes the noise more under load. and its a 96 cc long bed 350/4l80-e/14ff

    Sounds like your pinion bearings. They are just getting worn. Not bad. 140 wt will quiet it down a little. There is a little slop and the gears are making a little noise. Should last quite a while with care. When it quits howling and makes growling noises then its time to worry.

    Yeah bad beairngs. A rebearing is an easy job, espically on a 14 bolt. DO a pattern and backlash check to make sure the R&P are good. Then take it apart, change the carrier beairngs, and pinion bearings ( I reccomend taking the pinion sub carrier to a shop where they can crush the sleeve for you), put it back together and set the backlash to what it was before you took it apart.
