ahix1427 Posted January 18, 2018 Share Posted January 18, 2018 Brought truck into shop and was replacing ujoints at gear box do to having a little play in them and truck was real loose/wondering wile driving down the road. after replacing joints and getting truck back together I noticed steering would feel like it would grab and also would steer on its own. just slowly turn. made sure steering shaft was timed correctly. Called Mack their thought was gear box. replaced gear box with re-man Mack... still having the same issue.. Where to go from here???

hatcity Posted January 18, 2018 Share Posted January 18, 2018 low air in one tire? bad springs? King pins? tie rod?

Hobert62 Posted January 19, 2018 Share Posted January 19, 2018 (edited) Would it steer by itself sitting still or driving? Always the same direction?

Mackpro Posted January 19, 2018 Share Posted January 19, 2018 If it has the double U-joints on top of the gear box. Loosen the bearing retaining plate between the U-joints a little and drive it around the yard and see if that helps. The Bearing might be bound up on the shaft. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/52252-07-mack-granite-cv713-dump-truck/#findComment-390054 Share on other sites More sharing options...
Mack Technician Posted January 21, 2018 Share Posted January 21, 2018 10-4 to what mackpro said......Those little pilot bearings in steering shafts are the root of all kinds of evil.
