DIRECTION DIE PLAYS TO THE RIGHT SIDE

Hi everyone, my problem is this: I have a 1993 Citroen ZX 1.9D. I changed the brake discs and pads because the steering wheel was shaking when braking (actually, the mechanic did it). It's perfect now, it brakes like a glove box. The mechanic told me I should change the left control arm, where a new ball joint had already been installed. Now the problem is that when going 60 km/h or higher in a straight line, it suddenly pulls sharply to the right. It happens every now and then and it scares me terribly because I feel like the car is going to go haywire. I don't know if anyone can give me any ideas what it could be, so I don't kick the mechanic in the ass... because it didn't do this before. Since I plan to change the shock absorbers later, he told me it's not worth getting an alignment because it would have to be done again soon after changing the shocks. But I can't drive like this. Thanks...

Hello, the information you give to give you a correct diagnosis is very little, but the pull scares me a little without warning, I would review the semi -pile to verify that it is not a homocetic,
