no but i dont think mine is very healthy. When i first put it in it was noisy and weaps oil from one of the shaft seals. Its not noisy now. I did a couple of oil changes on it got quite a bit of metal swarf out on the magnetic plug. It didnt look good. Handling wise at speed its awful compared to the standard Ford diff. It doesnt hold a line and wobbles about all over the place.

Anyway i like to do a job properly. So ive got a 6 degree adjustable rear beam modified to take the supra diff. Ive got a nice set of billet gold anodised rear hubs from anembo engineering. I will treat myself to a set of coilovers for christmas and when everything is being swapped over get the diff rebuilt. Then with a bit of setting up it will hopefully handle as well as an old sierra can. Then see mr Martin at reyland for some top notch ap brakes and with sticky tyres it should be a bit of a weapon.
