No issues at all, feels very smooth and stiff / notchy feeling.

 

what brand & weight front differential gear oil would you recommend ?

 

as noted in this thread. 75/90 gear oil is what to use in the trans and front diff.. many use delvac 75/90 and i used to use redline 75/90 but switched upon install of an LSD to the delvac. for cars using an lsd ( modified ) there are strong admonitions against using any gear oil that has friction modifiers. but this is again only applicable if running an lsd.

this is the redline 75/90.

here's the mobil 1 delvac. remember to ensure it's gl5 type which the synthetic 75/90 is.
