Vibration while turning from stop
Hello new to forum
Have a question, I have a 2001 f-150 supercrew 4x4 57000 mi. When I start from a stop and make a turn it vibrates feels like it may be from the back I have replaced both u-joints and have new tires. It is worse when I turn to the right vs. left also when I tow a trailer it is real bad even if turn is graduale. Seems to be worse if I do a slow turn vs. a more agresive turn. I bought the truck used it looked like some one was in the rear diff cover so I changed gear oil. When I changed the oil the oil was almost black I wonder if they did not use the right oil it has a limited slip if that could be the problem.
Thanks

I have the same issue with my 98. It feels like slip diferential...or what I think that would be. I don't know enough to be certain but it's real pervasive when the road is wet too. Hope someone knows what the issue is!

I have the same exact problem with my '99 SCab 4x4. You can view the thread "1/4 turn shudder" in this forum to see what everybody else has written. Some thought it was not-engaged front hubs, and I still haven't recieved any more info on that - if anybody knows how to check that please let me know. Also, ck1404, could you go into more detail about this "friction modifier", ie: does it need to be added to the front diff also? I'm assuming no because there's no front limited slip, but where can I get it, any way to tell if it's already in there, etc. thanks
