Hello everyone, we have been a jeep family for a long time. We love our 2000 cherokee but with 3 growing kids we went and got a 2008 4.7
qudra drive 2 Commander limited and we love it. Here is my issue it needed the top front diff bushing replaced. You know the one everybody else has replaced. So I did the work at my job and one of our mechanics gave me a hand. Since we were doing one I did all 3. The diff cover was leaking so we took care of that as well. All I could find around here was the mobile 1 with the additive already in it says. I did order and had the mopar fm also the mechanic said we should go ahead and put it in also which I did agree with may have been incorrect. But for done and everything seems fixed and great no more clunk when shifting. Skip forward 2 days to last night it was raining and as I pulled into a parking spot I heard a sound like tire rub but I checked and no rub. This continued the rest of the night left and right turns more so on the right turns. From about half turn to full ****. All help is greatly appreciated. Could to much FM the additive already in Mobil 1 plus the mopar FM be causing to much slip and being exaggerated by the wet pavement?
Welcome to the forum Chy3280;
I'm no mechanic - not even close.
I can tell you in general, that Commanders are pretty finicky about the types of fluids you put in them.
More often than not - if you use anything other than fluids that meet what the factory specs call for, in any component, you could potentially end up having issues.
Your message is a little confusing, but if I'm reading it right, you are saying you put Mobil 1 in your differetial when you fixed the leak and topped it off?
I can't say for sure that's what's causing your problem but whatever differential you put that Mobil 1 in I would drain it and then in put in the factory recommended differential gear oil - or have it done at the dealership, whichever you prefer.
If nothing else, at least you will be eliminating that Mobil 1 with the additive you put in your differential, as a potential cause of your problem.
