SammyG Posted November 13, 2013 Share Posted November 13, 2013 Good day-I have a problem with my 07 Mack CXN613. I have recently developed a shake in the front end. I brought the truck in and had it checked over. The tires were chopped on the inside edges. The king pins had some play and were replaced. One the rear spring pins/shackles had some movement and both side were replaced right away. At the time there was a very noticable leak from the steering gear box. After the king pins, spring pins, and shackles were replaced the truck seems to want to wonder- steer right and correct to the left- then steer left and correct to the right- constantly fighting with the wheel. The leaking gear box was replaced and the problem went away for awhile. Now after 30 miles the fight with the steering wheel is back. Any ideas?Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/33491-2007-mack-w-steering-issues/ Share on other sites More sharing options...

SammyG Posted November 14, 2013 Author Share Posted November 14, 2013 The truck was aligned after front suspension work. After the issue developed the alignment was rechecked. The thing I don't understand is it was good for 30 miles after the gear box was installed.

SammyG Posted November 14, 2013 Author Share Posted November 14, 2013 Dry 5th wheel- I will check that. I did notice it could use some grease and it started again after attaching trailer!

felicello122 Posted November 15, 2013 Share Posted November 15, 2013 The nut at the bottom of the king pin may be too tight. Quote Link to comment https://www.bigmacktrucks.com/topic/33491-2007-mack-w-steering-issues/#findComment-216815 Share on other sites More sharing options...
SammyG Posted November 19, 2013 Author Share Posted November 19, 2013 The 5th wheel is well greased. Stil has what seems to be slight memory steer- lifted the front axle and all parts move smoothly. I worse with trailer attached. Quote Link to comment https://www.bigmacktrucks.com/topic/33491-2007-mack-w-steering-issues/#findComment-217534 Share on other sites More sharing options...
SammyG Posted November 20, 2013 Author Share Posted November 20, 2013 We lifted the front tires off the ground. We tried turning the steer tires by hand and it was stiffer then usual. They did move but seemed tight. We disconnected the drag link and the tires moved nice and smooth. We then disconnected the steering shaft and tried turning that. It seemed nice and smooth also. When we hooked up the new/reman steering gear it felt tight again.
