XLT hesitates on acceleration
I just picked up an 06 XLT w/ 4L SOHC and 38K miles. I haven't put alot of miles on it yet but I have two issues/questions.
During light to medium acceleration, first gear seems to hesitate, almost like it's ratcheting into gear. I don't notice this under hard acceleration. All other shifts, up and down, seem fine.
Also, at highway speeds I'm feeling a vibration from the rear, like a tire out of balance. I'm wondering if it could be a U joint causing both problems?
