Leonardob Posted October 22 Share Posted October 22 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 😭🙌🏻🙏🏻 Quote Link to comment https://www.bigmacktrucks.com/topic/74666-help-with-my-steering-shaft/ Share on other sites More sharing options...

topo Posted October 22 Share Posted October 22 I once replaced the u joints on a DM and lined up the U joints like I would on a drive line and it was not right then the slip joint out and turned it a quarter turn and it was right . 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74666-help-with-my-steering-shaft/#findComment-560575 Share on other sites More sharing options...
