Amsoil Gear Lube

[ROCK KRIES]

About two months ago I changed the rear lube to Amsoil series 2000 75-140. I did the figure eights and all was quiet from the limited slip. Now I am hearing a slight popping or chatter in left hand turns and when I hook up my 8000 lb boat with 600 lb tounge weight a loud chatter in left turns. Does this sound like I need to add a little additive? Right now the limited slip hooks up great,I do not even have to use 4 wheel on the ramps. How much wear will a little chatter do on the clutches? I am thinking of adding maybe 1/2 bottle of Mopar friction modifier, but hate to give up my good hook up.

I run Amsoil Series 2000 75-140 in my rear axle, and after about 10,000 miles, I had to add a couple of bottles of the Mopar Additive to quiet it down. It took more because of the Mag-Hytec cover. I have nearly 28,000 miles on the oil now and no more noise. I checked the fluid level yesterday and oil looks just like it did when I poured it in.

Rock, I too am using Amsoil Series 2000 75W-140. So far I haven't had to add any additional friction modifier however, I've only had it in the rear diff. for about a week and a half (I switched over from Amsoil Series 2000 75W-90). I would caution the amount of friction modifier you add... at least all at once. Start out by adding 2 oz. and drive around with that for several days to see if that works, adding 2 oz. more as the situation dictates. I know it's more time consuming however, it has proven to me to be a more accurate method of tuning the LSD characteristics than driving in circles (I mean figure eights). If you add too much friction modifier you will have reduced to no LSD performance depending upon the amount added.

I just changed my rear diff and put in Valvoline 75W-90. I added no friction modifier and everything sounds fine. I would have used Amsoil but i needed it in a hurry.
