I've just been phoned by my pal's son who cured a severe differential chatter in his '05 Explorer by replacing his fluid with some treated with Ford's XL-3 FM. He had used another kind earlier.
I have the same rear in my '05 Ranger (8.8" limited slip, 4.10) and want to change my fluid.
I bought RedLine brand FM thinking RedLine was king on all fronts.
I did a search here and read many posts from members who just included it on their "supplies bought/used" list. Nobody mentioned having had chattering etc.
What should I do for my middle aged girl?
