Hello out there, I recently bought a 2000 E250 with a 4.2l engine. I am detecting a bit of a rear end howl and was thinking of replacing with a trac loc?, posi trac? rear end.
Question did the E series come with this as an option, if so I will start looking for one and hopefully change it out. Oh, one more question, my van has an OD trans. what would be the ideal rear axle ratio for highway driving and still leave some torque for towing ligh stuff. Thanks all...Kewl
