I have a '93 LS400 with 145k mile. When I was making a u-turn the other day I had the steering wheel turned all the way to the stop. After this I noticed it was very hard to steer at low speed (parallel parking is almost impossible). I took it to my mechanic who ran through the diagnostic manual and came up with the problem as being the Pressure Control Valve which is attached to the P/S rack.
It sounds easiest to replace both the rack and PCV but it is rather expensive.
The request for help that I have is:
1. Does it sound like a PCV valve ?
2. Is it possible to buy a replacement PCV and not replace the rack (for less $$$)?
Thank you in advance,
Randy
