Hey guys!!! Long time no post. I have been enjoying my 2005 F-150 FX4 a lot!

I have had 3 oil changes in 9000+ miles and all else has been trouble free!

For the past 1000 miles, when I am stopped at a traffic light and turn right, it almost feels like the transmission slips between 1st and 2nd, but I know it's the rear end locked up, then it thumps and frees up and is fine. It is only when I turn right and never straight or left.

Any suggestions on getting this diagnosed correctly or fixed???

Thanks All!!!

 

If you have a limited slip try taking it in to the dealer. They will probably replace the clutch packs. Could also be slip yolk, if you have a 4x4.
