Hi
I recently took my diff out and replaced radial drive shaft seals
to do this i sat it on its side and knocked the seal in - both sides
now when i try and turn it by hand it turns then seems to jam ?? turn it back and rotates but then also jams later ?

could i have knocked something loose inside causing it to jam?
its a sierra diff
thanks

 

Send it off to Bara motorsport

 

I have replayed to this post in general . And sorry Toby Barra would be the last place I would send it into . any trasmichon place can check it out and replace any parts that might be needed for a 1/4 of the price
