Re: Trouble turning in 4WD
I have changed both of my diffs fluids with Royal Purple 75W90 and I have added a bottle of Gm Posi Additive to both and the lurching that my truck was suffering from has improved greatly. She only really jerks in corners on dry pavement now but in the sand and slick surfaces the problem has gone away until she reaches full lock in either direction and now there is just a little bit. I am happy to say that I no longer skid through turns! I hope that this helps you if you go the same route.
