Erratic steering wheel 08 ranger

[Yamaharx-1]

Hi, I replaced the rack and pinion in my 08 4wd ranger. When it was completed I filled the fluid reservoir and started the truck. The steering wheel went crazy erratic side to side jumping back and forth. It's so strong it's hard to hold straight. Any ideas?
Thanks

full of air you need to drive it around in circles in a big parking lot to remove the air.

The steering wheel bangs back and forth so bad you can't even drive it. Can it be a bad rack or no?

Did you center the rack before installing it?

I believe so but what is the procedure for it? Once in I made sure that there was equal length threads on each side before the tie rods.

To center a steering gear you lock some vice-grips onto the input, turn it all the way to one side, turn it all the way back to the other side while counting the number of turns, then turn it back the first direction half the number of your count.

So an example would be turn it to the left as far as it goes, turn it back right while counting, say it goes 4 turns, then turn it back to the left 2 turns.

Thanks, I will try that and see what happens. Imagine I should just pull it out and start from the beginning again?
