I just put in a pinion seal becasue my old one was leaking. I made sure that I tightened it back up and I added more gear oil, but I did not have time to take the diff. cover off and put the gm additive and gear oil, instead I just added gear oil. Now I am hearing a clicking noise somtimes when I go for drive to reverse and or reverse to drive, and if you start to break torque it a little. I know I sould change the gear oil and put the additive in, but will that stop it? or is there more to it ?



Thanks Dan

 

When I use the additive,the clunk goes away.About$7.00 at the dealer.

 

Put some posi additive in it. Also did you remember to torque the pinion nut to proper specs?

 

What are the torque specs. off hand ? Does anyone know ?


Thanks Dan

 

Anyone?
