2way diff problems!!

[ep82lunacy]

I purchased a second hand 2way last week for the s14 and installed it with fresh oil and done everything right I hope!!
Other than the odd clunk clunk when turning in a tight circle everything was good!! Now the 2way is very clunky and almost vibrates the car when going round a corner or roundabout!! Their seems to be a bit of play were the propshaft bolts into the diff?? Anyone experience this before?? Any help appreciated cheers

I used 75-90 Valvoline LSD oil!! this was the only oil i could get on the day!!

Did ya open it.you sure it is a two way and not a welded diff

Ya i checked the internals before i bought it!! Old oil was very good aswell!! Forgot to add that the diff was perfect for 2days until the knockin started happening
