Rear Differential

[Tim Quigley]

Has anyone ever had their rear differential go? i had some loud tire hum in the rear end for a little bit then the other day it felt like my axle wasn't releasing. Took it to my local garage and he said all the internals need to be replaced... anyone else?!

My MIL had one lock up on an old Ford LTD. It was nothing nice. But I digress, no I got rid of my 99 Burb before my rear differential "hum" turned into a nightmare.

Def try to find a used one if possible. Much cheaper.

Now would also be the perfect time to do a ratio change if you wanted too.

Sounds like the typical Gov-Bomb "soft" failure. This type of failure is common to the rear ends that haven't had the fluid replaced like it should. Some people luck up and have it survive well enough by just cleaning the diff really well and replacing the fluid (can't forget the friction modifier). If it's toast, now's the time to upgrade. There are far better designs than the Gov-Lock for not much more cost.

I grenaded one on my OBS. Was not pretty, or quiet. I bought a used rear end for $400.

Had the internal case crack on my 2006.
