Ain't Got a Clue

When it comes to mechanics I am the one person not to turn to for advice. Which leaves me asking a lot if mechanical related questions. Which has lead to this thread being created.

Here's my deal......

I have a 2010 Ford F-150 4.6L V8......yea yea I know, some of you will say "Thats your first mistake".....blah blah blah.....

Say I am approaching an incline which has a slight to moderate left or right turn to it. As I slow down to make the turn, going uphill, when I press the acclerator something in the back end of the truck jolts. It only does this on inclines to which I have to slow down and acclerate up. Driving down the highway is fine, uphills, downhills, around hills.....it drives smooth and has no jolting at all.

What could this be?

Do you have a limited slip in the rear axle? If you have no idea, read your manual or call the dealership, with your VIN number handy, and ask them if your truck has one.

If yes, then just deal with that, its engaging or disengaging with power and let off on a turn. Remember when you turn your tires, on the same axle, spin at different speeds. With an open carrier you spider gears work to allow the tires to spin at the speeds they need to to not 'chirp' or skid a tire. If your rear end is locked up (I would eat more fiber) and is not disengaging one of your tires is trying to spin to fast or too slow and causing force on the gears. Drive it till you hear a loud bang and pop and you dont go anywhere when you give it gas. Then take it in for a new rear axle. Until then, be a man and give it some gas when taking those turns. It will not jolt.

Your lack of driveshaft and u-joint grease could also cause this feeling. If you dont have a grease gun, swing by an auto shop and ask the guys to grease the driveshaft and u-joints for you. Give them a 10-20 dollar bill or a case of Natural light and be on your way.
