after doing few more tests today i come to conclusion that maybe my lower joint assembly is bad ,i guess,
here what i did:
i did test first,the
inside cab ,and nothing is moving,i put my dear wife to turn left/right the steering wheel and me i put my hands on the steering shaft to see if any movement up and down when turning,but was none!,
then i did the same test under the hood,and when i put my hands on the double joint and go up and down i can see little movement ,not much but is there and my wife said that she was feel it to the steering wheel when i was going up and down,,
so now question remains can the lower joint assembly here be changed,,is there a bearing or..?
thank you friends!
