Zebvance Posted February 22, 2014 Share Posted February 22, 2014 1988 mj 4.0 auto. About 5-6 months ago and maybe 2000 miles ago I replaced the power steering pump, lines, pully, resivor, and gear box. Replaced the gear box with a 99 Durango box. I noticed the steering would get stuff to the point to where it would feel like it was not working after prolonged periods driving on the highway. I would say 3 miles or more. When I would exit I would notice very stiff or no power steering and then after I would give it some gas it would come back. However I could be idling in park or cruising around town and never have a problem with it. So I replaced the power steering pump. This is the third one in 2 months. Same story with all the pumps. Also put another gear box in. Every thing is the same nothing is changed. Can some one explain this for me? I'm at a complete loss. Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted February 22, 2014 Share Posted February 22, 2014 Perhaps it has something to do with the steering linkages themselves or ball joints... I can't see how anything with the power steering system could be causing it considering you've replaced everything at least two times. Linkages and ball joints is where I'd start.

Zebvance Posted February 22, 2014 Author Share Posted February 22, 2014 All the linkages are new. Put serious offroads 1 ton steering in about 6 months ago. Ball joints however have not been replaced. But got a d30 I am building in the garage. Everything new, I plan on putting it in, in about a month or two.

onlyinajeep726 Posted February 22, 2014 Share Posted February 22, 2014 Could be those then, but I don't know. Is your draglink at an extreme angle from the pitman arm down to the knuckle or is it good? I can't think of what else it really could be but I feel like based on what's been replaced, it really can't be the power steering stuff itself. I know on my '96 XJ (stock everything) it was sticking just like you said. Around town fine, but on long stretches of highway/interstate, it would feel like it was locked in to place and I really had to jerk the wheel to get it to turn (almost wrecked several times like that). Turns on my passenger-side, bottom ball joint was worn out. I wouldn't have thought it would have that bad of an influence on turning but it did, frighteningly enough.

Jeep Driver Posted February 22, 2014 Share Posted February 22, 2014 Are you sure your belt is not slipping? We has a 4.0 that had a HB go bad and the pulley would spin on it intermittently........thus not driving the accessories. Link to comment Share on other sites More sharing options...
Zebvance Posted February 22, 2014 Author Share Posted February 22, 2014 Brand new belt and hub bearing as of this week. Not slipping. Link to comment Share on other sites More sharing options...
mvusse Posted March 1, 2014 Share Posted March 1, 2014 I wonder if for some reason the fluid is getting too hot and cavitating? That would pretty much shut down the pump. Link to comment Share on other sites More sharing options...
dasbulliwagen Posted March 1, 2014 Share Posted March 1, 2014 HB is Harmonic Balancer. If it is slipping around the rubber isolator, it will cause this loss of turning for all the accessories. Link to comment Share on other sites More sharing options...
