So I just changed both of my o2 sensor, and the car drives great but once I got on the highway I got a really bad vibration from around 40 to 60 mph . I mainly felt it in the rear of the car . Now here the part I don't understand , the vibration come and gose , after I run it for a while the vibration gose away . Now if this help my differential has gone bad so I hear that plus the vibration , feel like my drive shafe going come off.

So my question is the on and off vibration have to do with my differental being bad ?

Maybe the tran bushing / support bearing on drive shalf need to be changed ?

When changing the differental should I change the bushing too ?

Thanks for the help

I'm having the same issue. I'm going to change the transmission mount and go from there. you should try it too. Maybe you can get yours first and keep us posted!

Well I found out what my problem was , it wasn't my diff, it was my calipers , one in the front and one in the rear. Both were frozen. I found this out by doing two thing first I changed the line that goes from the calipers to the brake line once I did that the nose that I thought was the diff went away but I still had the 40-60 noise so we re looked at the breaks and saw that the calipers were frozen . Easiest way to find out if it froazn just drrive the crazy for 20 to 30 mins on the highway and then take it to a shop who was a heat gun , the heat gun tell you the temperature of your breaks if it over 200 then that where your problem is . Sorry if I miss spelled anyone I am at work
