while driving the steering wheel would lockup and I would have to force it two hands to break loose. Any recommendations on what it may be…thanks

 

I'm not aware of a failure mode that can cause the steering to "lock up". More likely you are intermittently losing pressure from the pump, causing the steering to default to manual, non-assisted steering. I've had this happen to me and it ended up being the flow control valve underneath the outlet port on the back of the pump. The nut on the valve came loose (the part labeled "plug" in the second drawing below), causing intermittent loss of pressure in the hydraulics. Once I tightened the nut, it was fine.

 

Consider that it could also be the steering column lock malfunctioning.

There will be a difference in feel between that failure mode and the one Joe described.

With a column lock, the wheel will move slightly between two HARD stops and you may also hear a click at each stop. With a power steering failure, the stops will be more resilient and won't make noise.

 

The steering column lock means you can't turn the wheel, period, and you wouldn't be able to overcome it, even with two hands. That's a very low likelihood.

 

I wasn't clear. Yes, there's an extremely low likelihood that the lock goes full-on. If the lock pawl were barely engaged for whatever reason, it could be muscled out of the way. I had a problem like that once.

Not saying your diagnosis is unlikely, but wanted the OP to read about the different feel between those two problems to know immediately which would need further investigation.

 

One of the things I've found over the years is the people who have never driven a car with manual steering (or worse, a PS car where the power fails) immediately think that the steering is "locked up" as opposed to just much higher effort.

 

I’ll check thanks
