power steering pump
You probabley did, I had a problem with mine last year and when I had it replaced the analysis was tha it had been run dry causing it to fail. the symptoms were not responding to turns and spotty reactons like delayed responses. when I had mine replaced I used a reputiable shop but they made a mistake and did not remove the vacuum pump and by doing so the seal in the vac pump failed and the job had to done over. so when replacing the
P S pump remove the vac pump and replace together. most parts stores have good prices on rebuilds, also make sure that the surface that the seal rides on is not groved , if so the vac pump seal will fail. Depending on the miles it might be a good time to get a seal kit for the vac pump from cummings, not expensive. Stormy
