I have a 2000 camry that has become very hard to steer. I have had a couple people tell me that it is my rack and pinion while others say its the rack and pinion u-joint.
I is hard to turn in both directions and if you listen you can hear a click when it turns.
anyone have any help on how i can determine what to replace?
Put it up on jack stands and get someone to turn the wheel back and forth. See if you can isolate that click. I believe that you can see the U-joint that you mentioned right above the rack & pinion. If you squirted it with WD40 and it fixed it that's probably your problem. However, if the U joint turns out not to be the problem the WD40 might wash away some of its grease and shorten its life span.
