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 😭🙌🏻🙏🏻

Hello, I have a 2012 granite dump truck and I'm in Houston Texas. (Very hot here) I would like to know what type of oil you recommend based on your past experiences. The transmission is a 13-speed maxitorque. I'm not looking to skimp on price. I just want to have the best oil to extend the life of my engine thanks a lot 🙏🏻👍🏻

Hello, good morning. I recently bought a truck. I changed his injectors and turbo. I started working on Monday and when the truck is loaded and I step on the accelerator so that it responds quickly, the message appears "check fuel filter" on the board no check engine light new fuel filters mack gu 713 mp8 Some ideas of what to review?

You are the best… problem solved. Thanks

Will you have any photos of the sensor that I should disconnect?

Mack mp8 2012 gu713 granite. I have a 2012 mack granite that had flaws at the time of doing the regeneration, we decided to clean certain things and change the turbo for an original mack one and it continued to give problems of def. We decided to eliminate the DEF and the truck was left with RPM failures, attached link to the video https://vimeo.com/987828534?share=copy This fault lasts a few seconds and then it is removed and the truck remains calm. If I touch the accelerator or the clutch, the fault occurs again. We thought it was problems with injectors and they were changed with their cup. And even the fault still exists. I don’t have any associated codes, I’m attaching a photo. The programmer tells me that that failure has nothing to do with the elimination. In addition to this, when the road test I feel the truck without strength until it reaches 1600rpm that I feel that the turbo has its effect and the truck grabs some speed I really don’t know what to do anymore, I’ve invested a lot of money and I still can’t work
