Pulls right on hard acceleration

[mf1026]

Has anyone experienced this?

Whenever I accelerate pretty hard (passing or getting up with traffic), it would pull to the right very hard and i could hear the tires kind of skidding somehow while it is this way until i have to slam on the brakes and then the ABS would go crazy while there is a big bang, then everything would be back to normal.

I am just not sure if the rear axle is twisted out of alignment or its the front wheel pointing into the wrong direction until the hard brake.

It could be one of the sway bars or any other bars that is loose/sliding in and out.

Any ideas or solutions you might have would be greatly appreciated.

could ya have a friend drive behind you and do a bit of looking at the wheels and leveling of the truck. in the old days i'd have suspected a broken leaf spring or your right front tire is still engaged to the xfer case.

Not sure but, check the ball joints & wheel bearings. This doesn't sound good.

Ok I will try that again. I have had the front end jacked up a couple of times and checked for free plays. I do know that my Pitman arm is worn and I am looking into replacing it soon.

I was hoping to see if someone has experienced the same thing I did. I have 170,000 miles, all stock and original parts except for the first fuel pump replacement 2 weeks ago.

So far, i did alot of inspecting last night. All motor mounts are intact, a little dry rotten but no movement at all. same with transmission mount.

We tried to make it happen again but it was harder to get it to happen this time. I realized it does it especially when it is colder out (like one raining morning to work when it was abt 48 out, it did that easily as i accelerated onto the freeway).

I got it to happen again when I accelerated hard making a right turn and then drive straight. It just pulled right and then slowly went back to normal without bang or anything.

I am starting to think its the front halfshafts or cv joints? When the front lifts a little, I would think it would slide out (extend as the front lifts) and then gets stuck for a second before it slides back in due to old grease. I would guess when its colder, the grease is harder which makes it more likely to happen. Does this make sense? It feels like it is the problem. I am not sure which side, maybe passenger side. I have inspected the boots but it looks sealed but grease could be dry inside.
