hello i have a 02 wrx and i have no power steering in slow tight turns. i checked my fluid and its not leaking. i got under the car to look at the rack and pinion and they were no obvious signs of wear or fluid leaks. i looked at the hydraulic pump and again no leaks or signs of obvious wear so im at a loos as far as what to do. the car has about 115k on it. what do u guys thinks it cud be or wat shud i be looking for? wat kind of tests can i do to try to figure this problem out? if its the rack i want to be sure before i go spending 300 and not fix the problem. so if anyone has some expertise on this id great appreciate it thanks.
