I have a 1991 LS 400 with 207k, I have the stiff steering problem. I found a leak in the power steering high pressure hose. Changed the hose thinking that was the problem. Day 1 it drove smooth, then back to the same ole stuff. checked the power steering resuvoir its has the same level. Has anyone ran into that, or know what the problem is, I would greatly appreciate it. Thanks

 

Well, most likely it wasn't the hose, it was probably the air valve in the pump, it kind of drips right onto the hose, so it does indeed look like the hose. Search the forum, there's tons of info on that repair.
