Groaning sound when turning

[hgeranium]

I was finally able to get the site to cooperate so I could ask about this. For the past few weeks, I’ve noticed that the Jeep has started to make some groaning noises when I steer. It’s not the fluid, it’s properly topped off and looks/smells fine. I’ve yet to experiment to see if things change when the fluid warms up (will test when I’m off work in about an hour). I had a remanufactured gearbox with a high pressure PS hose put in about 10,000 miles ago.

 

Even with the groaning, steering is still effortless, it’s mostly just that annoying sound and feeling in the wheel. With that, I am guessing that it’s either the pump itself or air trapped in the system. For the latter it seems less likely since this problem just came up recently and I wouldn’t have done anything to introduce air in the past 10k miles. I’ll have to double check the belt tension when I get home just in case but I don’t think that’s the problem either.

 

I’m also assuming it’s not the gearbox because I would either be leaking or feeling some serious steering woes.
 

I think starting with bleeding the air would be good. I’m curious if there’s any special techniques for the Renix or it’s like any other car.

leaning on air in system...   is my guess

mine did it when cold,  I suctioned some fluid off and put some lucas PS treat in it..  seemed to have helped... this was before a pressure line replacement by shop when doing other work,  has not done it since... there was a line leaking....  so maybe allowing air into system?

 

had similar issue on a dodge 3500 cummins,  suctioned out fluid multiple times and replaced to effect a fluid change over time..  helped it a bunch...

was some fancy arsed $$ fluid also...

Could be the pump dying too, but I’d start with looking for air in the system.
