When ever I make sharp turns there is grinding sound coming form the rear end. I was going to change the gear oil in the rear end but just wondering if anyone has experienced this sound and has any idea what this could be?

 

Did it just start doing this? If you have recently changed the rear diff fluid and didn't put trac-lok additive in, it will make grinding noises...that is if you have track-lok anyways.

 

It has been doing this for a couple of weeks but i really just started to notice it now. When I do change the oil, is it just half gear oil and the other half the additive?

 

The additive comes in a small bottle (4 oz?) and the rest gear oil.

 

make sure that you have a track lock before you go buying that crap its expensive and you dont need it unless you have traclock

 

Yeah, if you look in your glove box it should say something about trac-lok...if not, then it should be on the axle on the info tag.
