Help with my steering shaft

[Leonardob]

Hello, good morning.

I have a Mack gu713 2012

My gearbox was leaking oil and I sent it to be repaired.

Take advantage of the time and my truck mechanic the u-joints of the steering shaft.

When I reinstall the gear box, and the steering shaft I notice the steering wheel direction harder than normal.

I assumed that the gear box didn't look good. I down  the gear box again, I send it to check and they tell me that everything is fine with it..

Doing and asking someone tell me that the problem may be that my mechanic did not replace the u-joints as the previous ones were.

And the truth is that I would like opinions.

(I already changed the steering pump)

(I also took the air out of the pump with the tires in the air)

 

if you help me I send you a tip . I need my truck back 😭🙌🏻🙏🏻

The  u joints must be phased properly,someone will chime in and explain it I’m sure..
